This tendency of the units ng o to become shorter with decreasing age might reflect le ri e c increasing rates of faunal turnover, but alternatively The accelera on of faunal change might reflect a greater effort or need for stratigraphic sa du th towards the end of the Pleistocene precision or an increased abundance of the fossil record.

The fact that also in African localities in faunal turnover from about 1,2 Ma onward, be- op er species longevity decreases, suggests that the rates coming more pronounced within the Middle and of evolution and faunal change increased in more re- still more in the Late Pleistocene.

Company XYZ will turn out to be your ally when the mob comes with pitchforks, torches and the Channel 4 news crew. At least I hope the company down the street will recognize the need to be your ally before the mob turns on it.

My hope is this note will cause company owners to think on the ways proactive community relations campaigns can set the business up for continued success.

For example, at a marketing conference about a decade ago, I learned that Ford Motor Co. Nobody cared about engine faults in their Jag. In fact, owners made excuses for their Jag being in the shop all the time because they loved their cars so much. What the marketing folks at Ford figured out was they needed a campaign that touted the awesomeness of being a Jaguar owner. Just to be clear, I do not own a Jag. But the positive campaign spoke to car owners like nothing else could.

The award recognizes individuals for outstanding contributions that have advanced broad goals of the association. The organizers expect more than attendees from different countries.

The company has 12 divisions and two affiliated companies in Washington, Oregon and Idaho. Lakeside has approximately employees and operates 17 hot mix plants and a rock crushing facility. Lakeside Industries has a long history of safety. Over the past several years, the company has been promoting an exceptional safety culture based on engagement and empowerment of employees for safety awareness, hazard recognition, voluntary compliance and improved decision-making.

We not only want our employees to go home safe from work each day, but also return to work safely each day as well. Each task is extremely important to making our company safe and successful. Foister and Markwald are friends on and off work.

They both are proud of how they have provided a gift for Lakesiders of all ages that has been well received already throughout the company, the communities it serves and the construction industry. Melanie, previously a middle school teacher and mother of two, joined Lakeside in Jaylynn is a second-generation Lakeside employee beginning her career in She has worked in various capacities, including traffic control supervisor, assistant superintendent and superintendent.

We also employ the option of tanks that allow the specific heating and agitating requirements that facilitate the storage and use of these modified ACs. One of the more recent technological developments comes in the form of a testing device to extract asphalt binder from hot-mix asphalt HMA mixes and automatically separate the components for analysis.

Rather than devoting days to traditional reflux extraction to determine binder content from an HMA sample, or relying on ignition ovens and correction factors, technicians at S.

The Asphalt Analyzer manufactured by infraTest USA, Walpole, Massachusetts, avoids technician exposure to highly flammable and dangerous solvents such as trichloroethylene and can provide results in about 90 minutes.

According to infraTest USA, the new PG model is equipped with a second solvent circuit allowing for the extraction of rubber modified asphalt mixes as a stand-alone procedure. This becomes more critical as rubber use in pavements increases, and as new processes are implemented for incorporation of the rubber.

Testing is a division of State Materials Engineering, and is an independent professional engineering firm specializing in consultation and testing of construction materials. President Jay Behnke, P. The technicians continue to upgrade their training, with many of them maintaining the highest degree recognized in Illinois.

In first quarter , the firm added the PG model Asphalt Analyzer. Also, as we work on specification development for binder grading of AC from field samples—including both virgin and recycled AC components—it really improves our ability to get samples over to the binder testing lab with minimal effort and minimizes the exposure to solvent.

Left: Here you can see the extracted and captured ground tire rubber from a hot-mix asphalt sample. Photos courtesy S. Right: One of S. Behnke concurred that the testing company has been running tests at full tilt since adding the equipment in early March.

Behnke explained that getting timely results on the pricy material of liquid AC in a mix design is a driving factor in design and control of HMA projects. GTR offers the advantage that it makes pavements less prone to both cracking and rutting. An HMA pavement needs to be strong enough to resist rutting under traffic but flexible enough to resist cracking caused by thermal and other stresses. Each property, rutting on one side and cracking on the other, can be assessed by S.

The net effect of rubber, when used properly, is to stiffen the mix without sacrificing flexibility. In my opinion, the one that correlates to field conditions the most and is the most repeatable is the DCT.

Behnke explained that the Asphalt Analyzer PG model is important to the use of these new mixes because of the ability to separate out the rubber and confirm contents. Every process is a little bit different. Technicians can assess the new performance grade and the percentage of the mix the binder comprises with confidence. For example, the binder trapped inside absorptive aggregate or aged fractionated RAP gets pulled out of the aggregate during the combination of centrifuge and reflux process of the analyzer.

Using vacuum pressure, rather than heat to dry back the aggregate speeds the process without the potential to break down aggregate. Testing is forging a path to assist agencies in obtaining high quality, high performing pavements. Testing performs verification testing for several agencies in the state including the Illinois Department of Transportation, the City of Chicago and the Illinois Tollway.

Testing is constantly involved in initiatives to improve quality such as the one with the National Highway Institute NHI on revamping its Transportation Construction Quality Assurance class. Whether a sample to be tested comes from a S. Proper lab accreditation and adherence to test standards are critical. American Asphalt Co. One is a 5-ton Stansteel batch plant. The other is a TPH Dillman duo-drum.

Putting the two on the same property made perfect sense from a permitting, footprint and cost standpoint, and inspired the intriguing idea of feeding both plants from one cold feed system. Serve the Customer American Asphalt Owner and President Bob Brown has performed the various jobs at the asphalt plant that his employees are required to do, thus he is aware of what his employees need when it comes to getting the job done right.

When I started, the previous owner stayed on and showed me how to operate the plant. So I have a real appreciation after running the plant, running the loaders, charging the bins, welding, wiring, fixing. I know how hard it is. I know how hot it is…. Jennings made a point of stressing that the team added the 5-ton batch plant with tons of storage capacity to the Burlington site and modified it to include a fifth hot bin to accommodate additional mix designs for larger customers while still providing commercial mixes that smaller and mid-size customers request.

The bins are supported by formed legs and have double structural stiffeners to support the walls against the extra weight and pressure from the aggregates. Each side of the bin has a custom designed, heavy duty radial gate to allow for consistent flow.

The feeders are equipped with a direct drive 5 horsepower motor and gearbox to deliver consistent power to the feeder without having to deal with belts, sheaves and pulleys. All the feeders are equipped with variable frequency drives for optimal performance on all the mix requirements. The Dual Bin System is outfitted with two inch by foot collecting conveyors, which feed the materials to both plants you see here.

By adding a fifth hot bin, we can accommodate intermediate and top mix designs for our larger customers as well. Reliable Asphalt Products also re-engineered the dust entry points and added a custom flop chute under the tower to feed the asphalt into the. We also upgraded the hot oil system and added two additional AC tanks.

We also added a new control system, which allows the plant team to take advantage of the latest plant operating technology. To make their luxury product available to more customers, the team at American Asphalt looked at adding another plant to its assets.

It came back to where it would be more financially responsible to stay here [Burlington site]. We would also add only a couple more personnel instead of adding the five or more people another full plant and site would require. The American team went with a dual feed system that allows both plants to use one set of bins. The RAP Dual Bin System is comprised of eight foot by foot cold feed bins that are partitioned in the middle to allow for two feed conveyors on the bottom of each bin.

Jennings said that also gives them room to have an extra bin or two in the event of emergencies. American Asphalt recently added the 5-ton batch plant with tons of storage capacity to the Burlington site and modified it to include a fifth hot bin to accommodate additional mix designs for larger customers while still providing commercial mixes that smaller and mid-size customers request.

Plant Manager Chris Jennings shared that they use a single Komatsu loader to feed the system for the two plants, which also lowers their cost to produce. Decisions are focused on keeping costs down for production and the customer. With the dual feeds, each stacked bin holds a total of tons. Fifty tons go to the feeder for the drum plant; 50 go to the batch. At this time, they use a single Komatsu loader to feed the system.

One loader for two plants lowers their cost to produce, making them a low-cost provider. The ideal situation is they feed to the center of the bins. We are always looking for the latest advancements and technologies available to keep us one step ahead of our competition.

Respect, Integrity, God honoring, Honesty, Trust. Every employee is empowered to be able to make our customers feel not only important, but a vital part of our team by treating them RIGHT. By maintaining constant contact with the customer, we keep our production teams informed of the status of every job, even while the job is in progress. The more we communicate, the better we and the customers become. We want American Asphalt Company to be the producer of choice.

Under the direction of Bob Brown and management of Chris Jennings, the American Asphalt team has created a unique plant layout that will greatly. American overcame issues with both permitting and plant layout space with such an innovative design. The fact that they were able to add a 5-ton batch plant and silo system without rearranging the existing facility is amazing. From start to finish on this project, the American Asphalt team has done a tremendous job in both planning and execution.

By focusing on a plan to better serve their customers, American Asphalt has set itself up to be a leading organization in the industry both locally and nationally.

Add the optional V-Pack stack temperature control system to operate in the most efficient way possible. With new engine emissions regulations and electronic data logging rules out there, advanced technology can either help or hinder the regular maintenance regimen. Producers have streamlined processes at the plant; contractors have nailed down best practices in the work zone. Operating a commercial vehicle means a state or federal inspector can stop you if they notice something that appears unsafe.

This behooves you to perform routine maintenance for best and safest operation in between your mandatory periodic inspections.

One of the most important items to ensure is working on your truck is the backup alarm. Many companies have instituted the policy that a haul truck with an inoperative backup alarm will not be allowed on a job.

This means an independent driver could show up with a load of material and get kicked off the job, making him financially responsible for 18 or so tons of cooling mix. To track maintenance activities, drivers and mechanics have the help of modern technology.

Even before large original equipment manufacturers OEMs joined forces to standardize data points, they were developing telematics to gather information on the way engines run, to detect faults in equipment, to schedule maintenance actions, to streamline machine safety, to monitor emissions controls, and to gather data for fleet management. For instance, the team at Volvo Construction Equipment has telematics packages standard on 7 articulated haulers, 23 excavators, 11 wheel loaders, and as an option on two pavers, 2 soil compactors, 4 asphalt compactors, 4 compact wheel loaders and 8 compact excavators.

Then the Volvo Trucks team has the Gateway telematics system to monitor and gather data for commercial vehicles. Other OEMs have recently released telematics solutions for on-highway trucks. In March, Caterpillar announced its on-highway truck fleet solution complementing telematics that are already standard on their construction equipment. Back in the mids, OEMs recognized that many contractors have mixed fleets, which meant the end user had mixed data coming in on different types of screens.

Different machines were failing to talk to one another in different languages. That had to be reconciled some way. By Feb. Fleet managers know there are more data points than the six listed in this paragraph, and OEMs kept working to make the standard more robust for the end user. This gives contractors and fleet managers confidence that the data-monitoring across the fleet is gathering, interpreting and delivering information in a uniform manner.

No matter what tier level your engine is, you are responsible for keeping it, and the components surrounding it, in top working condition. Check the belts and hoses on a regular basis, too. Make sure the air cleaner indicator gives you a good reading. Consider the new after treatment systems available now. You want to monitor whichever system your engine manufacturer uses and perform basic maintenance as the OEM recommends.

While you can take care of routine cleaning and checks on your own, error codes indicate problems that may require professional help. He mentioned onboard diagnostics OBD and liability.

If you receive a warning light or fault code from your OBD regarding your Tier 4 engine, you may be breaking the law if you make the repair yourself. Piech explained that changing the way an engine runs has both safety and environmental impacts. Additionally, if there is an error code flashing on the display, your best bet is to call the nearest servicing dealer so they can diagnose and fix the problem.

Think about oil changes for a moment, because even this. If you pick up the FA-4, it is designed to work optimally for the engines. Some of the goals of upgrading from the former CJ-4 oils to the PC category are to protect engines no matter what level of shear stress the oil will undergo in the engine, to protect against oil breakdown due to oxidation under higher operating temperatures, and to safeguard fuel economy.

This will require changes in engine oil composition, so they can withstand more heat without sacrificing engine protection. The new FA-4 engine oils will be offered in lower viscosity grades and are designed primarily for next-generation engines to help maximize fuel economy without sacrificing engine protection.

These FA-4 oils may have limited backwards compatibility, and would be labeled as such. If you feel the need to spend seven or eight minutes on this, Chevron has prepared a series of short videos at www. Part of your daily, pre-shift walkaround should include looking at this sign to ensure it is clean, legible and in good repair.

Keeping the haul truck in top notch condition does more than keep you in compliance with the DOT. Each piece requires maintenance for optimum performance. Start at the top. You want to inspect the tarp—or canopy— each day to ensure it has no rips or tears.

Look at the mechanism that lowers and raises the canvas to ensure it moves smoothly and completely. This leaves room for wind to whip in and cool the top of the material into a segregated shell while you drive from the plant to the job site.

This system runs on two cables that unroll and retract the canvas along rails, forming a lid on the truck body when closed. Telematics is, at its core, machines talking to machines. Photo courtesy Roadtec, Chattanooga. While inspecting the tarp before your shift begins, look into the truck bed. Take the time to pick out plastic wrappers, soda cans and anything else that has gotten in.

Anything you see in the bed of the haul truck will get covered with mix and then will get carried into the hopper of the paver. As the haul truck driver, you can stop that financial loss with just a few minutes of cleanup during your preshift walk-around.

Another way you can make your vehicle appealing to the paving crew is to make it com-. That leads to a potential mess each time trucks charge the hopper—giving laborers extra shoveling to do and an extra repair for the mechanic. Your truck will be more compatible with the paver if you can get the mud flaps out of the way, as well. Each individual state department of transportation DOT has different requirements of haul truck mud flaps— splash guards. Then look into systems for easily lifting the flaps out of the way.

When you back the truck to the paver, you stop before making contact. When the paver operator moves the paver forward and brings the push rollers into contact with your vehicle, the push rollers are to touch the back wheels of the haul truck. If the mud flap is in the way, the push rollers now have the opportunity to deliver a jerking motion as the tractor moves forward. This will cause segregation in the mat. The push rollers also have the opportunity to tear the mud flaps. This means a repair for you later and possibly a chunk of polyurethane in the mat, which is another quality control problem.

The push rollers also have the opportunity to leave asphalt mix on the mud flaps, which means more cleaning for you at the end of your shift. None of those scenarios is an efficient use of time or materials. Instead, look for a system that will let you press a button in the cab to hydraulically lift the mud flaps when you enter the paving work zone. Or use this idea from Murray. He has extended the outer flaps of his rig from heavy duty chain. The chains keep the flaps hanging at the proper height for his DOT regs, and allow him to physically place the flaps on the fenders to keep them out of the way while he discharges the load.

As you can see, haul truck maintenance goes beyond changing fluids and filters on a regular basis. It goes beyond handling the big emergency repairs that crop up. By performing daily inspections and regular maintenance, you keep your vehicle in compliance and enhance your ability to contribute to a quality paving team.

Today, Coastal Bridge employs between and people in the asphalt division of the company, which also has bridge, industrial and commercial divisions. Its four asphalt plants—all Astec double drums running tons per hour—are located in Baton Rouge, Convent and Lafayette, Louisiana, and in Tampa, Florida.

Roughly 70 percent of the , tons of mix it makes annually gets laid by its four laydown crews on projects ranging from parking lots to interstate highways. In the spirit of expansion, Coastal Bridge bought the Tampa plant just two and a half years ago, hoping to add another , to its annual tonnage.

And, in the near future,. Coastal Bridge also expects to add a fifth crew, based in Tampa. And, in , Coastal Bridge purchased its first Stansteel Accu-Shear Blending System to continue its history of continuous growth and improvement.

After experiencing a slew of unexpected benefits, in addition to the ability to foam its mixes, Coastal Bridge purchased a second Accu-Shear for one of its other plants. But, the road to this point was paved with plenty of issues—no pun intended. When Coastal Bridge first began foaming its material eight or nine years ago, their foaming gun was a pain. The AC going through would often clog the water ports.

These conversations just so happened to occur around the time Louisiana agreed to allow latex-modified asphalt cement AC to replace PG polymer modified AC. But, it would still be a while before Langley would get the equipment he now knew he wanted. Instead, Coastal Bridge purchased an inline blender. So, the company tried a different, fluted blender and placed it on its Lafayette plant.

Although it worked much better, it would use more latex to obtain the same values—1. So, finally, the company purchased the Accu-Shear. The tests were consistent, the whole nine yards. It was great. Its Tampa plant uses the foaming system that came with its Astec plant.

Langley estimates that foaming has saved Coastal Bridge between 8 and 10 percent a year in fuel costs and has substantially reduced its carbon footprint. By using the Accu-Shear, Coastal Bridge also saw the amperage draw on its slat conveyors decrease when running a dynamically foamed mix.

Langley also discovered he could keep foamed mixes in the silo longer and that the material released and flowed better. Generally, Coastal Bridge limits the range it hauls mix to 80 to miles away from the plant. But, with properly foamed mix allowed to be made at a lower temperature, Langley reports they can go up to 30 percent further without reductions in temperature. Langley reports seeing increased compaction on foamed mix, even when the crew uses the same roller, in the same manner, with the same number of passes.

That means the crew can reduce its compaction effort by up to three passes, in some cases. That means the crew is moving faster with fewer passes, an increased paver speed, and is laying more in terms of total tons by the end of the day. Coastal Bridge is one of only a few companies using liquids modified with ground tire rubber GTR.

Coastal Bridge acquired the plant in Tampa, seen here, only two years ago. It plans to significantly ramp up production at the plant and establish a fifth paving crew in Tampa. After noticing its many benefits, the company purchased a second Accu-Shear for another of its plants. In Louisiana, Langley said, the state wants to see a reduction in temperature if a plant is foaming its mix. However, the lower limit is typically degrees. Coastal Bridge runs at degrees, for a bit of added flexibility.

That extra bit of heat also had a positive impact on the mix quality. That requires suppliers to write a letter confirming their materials can achieve those standards, but Langley said suppliers are often hesitant to do so. Rouge plant. Coastal Bridge performs nearly every type of test for virtually any specification, Langley said.

It has labs in each of its plants, but its main lab is in the Baton Rouge plant. The fancier tests we ship out to private testing labs. Improve Asphalt Quality: Low-watt density heaters dissipate consistent, controlled heat on the sheath. PHCo has been supplying customers with a cleaner, safer and more reliable heat source since To learn more, call us at or email info processheating.

With the Accu-Shear, users can buy them with a handful of ports to inject several different liquids at the same time, or simply as a water foamer. Langley is even thinking about getting a second Accu-Shear for the Baton Rouge.

First, he wants to better integrate antistrip into his mix. Louisiana requires plants to use a minimum of. Langley said most plants use an amino-based antistrip. Web Services is an exciting new interface available for your Libra Generation3 systems, opening the path to critical data sharing from anywhere.

The Accu-Shear comes with a gallon water tote with a fill valve with auto shutoff, mounted water and electrical enclosures, and lifting eyes and forklift pads. Second, he wants to do some experiments with rejuvenators and expand the variety of products he may want to add, especially as he continues his RAS and RAP experiments. Operating this drum results in real savings that add up.

Operate in the most efficient way possible and save fuel with the V-Pack TM stack temperature control system 2. Producers have streamlined processes. This installment looks at the roof of the haul truck cab. The paver operator, dump man and screed operators are tasked with watch-. Their attention is typically focused downward, not up.

If the paving train moves forward at 20 feet per minute, the paver may push the truck, with its body in the air, right into a mature tree branch or—worse—into live wires. The downtime involved when a truck gets tangled up in wires amounts to thousands of dollars at best, serious injuries at worst.

Other crew members should not approach the truck and should not attempt to untangle wires. A member of the crew will contact the utility company, of course, but will also contact emergency responders to assist.

Trying to exit the cab before the utility company has ensured power has been cut off to the affected wires can result in serious injury or even death. Truck drivers still need to be on the lookout for dangers overhead.

When independent haul truck driver Steve Murray wanted extra safety, he in-. Construction Angels Inc. Our goal is to assist the family at the beginning of their grieving process with hopes to provide them with a sense of comfort, both financially and emotionally.

Construction Angels wants to make an everlasting impression and impact within the industry, one family at a time. The third annual event was held at the Bergeron Rodeo Grounds in Davie, Florida, April 15, and featured an all-day battle of the best chicken wings and sauces from at least 14 of the best restaurants in the area with celebrity judging.

Live rock and country bands entertained a record-setting audience. Because Construction Angels is a national organization, Ronyak seeks ways to expand its good work beyond the headquarters of Florida. A Michigan contractor, Giannetti Contracting Corporation in Sterling Heights, is fundamental to that recent piece of success.

Construction Angels also provides grief counseling to those families who have lost loved ones in our industry. We have partnered with various organizations and charities to ensure Construction Angels is able to assist these families during tragic times. Our goal is to operate in every state and to assist these families around the United States.

To help the organization help more families in their most dire time, everyday workers can get involved without traveling to Davie, Florida, for the annual WingsFest.

Ronyak has another, easy way workers can pay it forward to help one another. By providing the form to your human resources department, you authorize the payroll department to deduct a dollar or two—or whatever you are comfortable donating—from each of your paychecks. The way Ronyak explained it makes perfect sense. That may not seem like much to the person doing the donating, but it adds up for the Construction Angels and for the families who suffer a tragedy down the road. At press time, Construction Angels was hard at work preparing for the next fundraising events in the four regions in which it operates, and working to incorporate offices in additional states.

AsphaltPro magazine is honored to bring attention to this good work and to increase awareness of construction safety.

Other electrical fires result from improper operations and maintenance practices. Mechanical causes are primarily a result of hydraulic brake systems and main shaft bearings that overheat; this tends to occur in high winds, during stormy weather, when the blades spin out of control and the brakes overheat and fail. Lightning strikes are a well-documented fire hazard. Not all lightning strikes ignite turbine fires.

The sparking with flammable fluids or vapor clearly poses a fire risk. With more than 80, turbines currently in operation5, turbine fires will continue to increase. The industry has a long way to go in preventing, tracking, and reporting turbine fires. Everyone who lives in the shadows of these giant machines deserves protection to property, livestock, the wildlife, and surrounding fields and meadows.

Burned out and rusting turbines not only mar the landscape, but also the reputation of a growing industry. She is also Executive Member of the group Turbines on Fire. Wind guarantees can be notoriously difficult to understand and navigate; as the industry moves forward with increasing technological and financial sophistication, the guarantees that back the projects need to keep pace.

Ultimately, each project contract is unique, and requires a granular-level understanding of its fine print. Nevertheless, with a general framework for understanding the different types of risks that underlie a project, and the guarantees that are available to mitigate those risks, owners can make informed decisions in this increasingly sophisticated environment.

A breakdown of these risks helps an owner determine which they are positioned to take on themselves, and which require guarantee coverage. Perhaps the most obvious is Resource Risk: will the wind blow? However, this is likely to change as certain service providers are able to leverage internal or external resource assessment expertise. Even more complex is Market and Regulatory Risk. Market risk can include basis risk, curtailment, and anything that may impact project cash flow.

Regulatory risk includes the ever-present particularities around taxes and tax credits, environmental issues, NERC regulations, and a whole host of others. Failure risk refers to unexpected, and generally catastrophic events that can bring down a plant, or at least a significant portion of it.

This includes major component and substation failures, as well as serial defects that have the same impact. Degradation can include power curve issues and blade deterioration. Another way to view the framework is to visualize which risks an Owner is still exposed to under each type of guarantee, as shown in Figure 1. With a time-based guarantee, an Owner is still exposed to most performance risk, all resource risk, and all market risk.

On the other end of the spectrum, with a revenue guarantee, the guarantee provider holds almost all of the risk. As guarantees become more sophisticated, the service provider will need to be supported by additional subject matter experts. Service providers specialize in performance; resource risk is typically well understood by a resource assessment group; and market and regulatory risk is handled by asset managers or a finance team.

Unfortunately, guarantee structures and terms and conditions have not been standardized across the industry. Here are a few helpful hints to think about as you review your guarantee. Guarantee Target and Calculation: The target generally expressed as a percentage is what your guarantee provider is obligated to hit or pay damages. Guarantees are typically in the mid to high 90s for utility-scale plants, but can be lower, depending on how.

Figure 2: Tracking Performance and Exclusions Wind averse your guarantee provider is to taking on additional risk. The calculation compares actuals to expected uptime hours, production, revenue , with adjustments for any exclusions. Exclusions: Understanding what events are excluded is key to understanding how much risk is being passed on to the guarantee provider.

Some categories of exclusions are straightforward, such as Force Majeure or curtailment; others are more questionable, such as scheduled maintenance, major component replacements, or degradation. In addition to defining exclusions, the guarantee provider should also explain how they will track excluded events.

If this is not defined upfront, the guarantee could become an administrative burden. An example of tracking performance and exclusions is provided in Figure 2. Owners might also want to incentivize the guarantee provider to increase performance with bonus payments. Helpful hint: be wary of step calculations e. A better bet is linear calculations, where each additional unit of production is equally incentivized.

As the industry continues to advance, so too will the guarantees that backstop performance. However, beyond the guaranteed performance levels, it is important to understand the risks that are being mitigated, and to structure the guarantee so as to avoid administrative burden, and provide true and transparent coverage. Prior to joining EDF, Shuckerow worked in economic consulting for the energy industry.

It is assembled on the ground and then raised into place utilizing its own apparatus. Large, horizontal axis wind turbines are becoming a ubiquitous aspect of the landscape — both onshore, as well as offshore. Designs and efficiencies continue to improve, and costs keep coming down. As the wind market matures, more and more players drive market efficiencies, which helps to lower the price per kilowatt-hour.

By , total worldwide wind power capacity is expected to double over levels. Dimming visibility You may wonder, what has saved vertical axis units from the history books? Weight: 9lb 4. Where efficiencies used to be in the 7 percent range, new generation vertical axis wind turbines are seeing efficiencies of greater than 60 percent. Unlike horizontal axis based wind farms that have a very rigid cost and placement structure, vertical axis units offer a refreshing degree of freedom.

Vertical axis wind turbines can be placed wherever there is wind. This includes the rooftops of buildings in. Power per acre is still greater than 1. There are many places around the world that are hesitant to embrace wind power for fear of having infrastructure destroyed during hurricanes and typhoons. Vertical axis units are robust and heavy, and have been tested in winds to mph. Vertical axis units can effectively power micro grids and buildings. They work well on manned and unmanned offshore oil and gas platforms.

Through innovative engineering, vertical axis wind turbines have come into their own, and provide a viable and cost-effective solution to the 10kW — 2. With new and highly efficient scalable designs, and the ability to be placed in unconventional locations, vertical axis turbines can extract power where nothing else is suitable. Windy but environmentally sensitive locations – near migratory bird routes or bat roosts – can now be safely addressed.

Areas where discreteness is desirable can now be serviced, while still maintaining the visual appeal. Reliable, scalable, and long lived, vertical axis wind turbines have earned their place in the burgeoning renewable energy and wind power marketplace.

Doug has spent a career working with leading edge electronics and control systems. Since , Doug has focused his efforts on the burgeoning renewables market, with a focus on wind power and power grid monitoring big cities, or areas with height restrictions due to municipal ordinances or nearby airports. Vertical turbines are silent.

Bats and birds see them, and avoid them. Vertical turbines can grow with need as opposed to need attracting use. Vertical axis wind turbines are omni-directional. This means that, regardless of the direction the wind is coming from, a vertical axis system will capture that wind and turn it into energy.

Large, horizontal axis units can pivot at the head, but responding quickly and repeatedly is tricky for these designs. A common criticism faced by vertical axis wind turbines is that, regardless of how efficient the design may be, they will never be able to produce the same power as a taller, traditional unit of equal capacity.

At a given height, wind power is related to the friction coefficient associated with the terrain characteristics around the location being measured. Flat prairie or bodies of water have very low friction coefficients around 0. Under such circumstances, power generated will be similar. For high friction coefficient areas around 0. If a horizontal axis design is inherently better at capturing the greater wind power contained in the more laminar airflow at altitude, why have this discussion?

The cut in speed for new vertical axis design units is lower, and optimal power can be generated at much lower wind speeds.

ROI is in the range of 7 — 8 years; with a design life of greater than 60 years, vertical axis units offer tremendous. John Selby has been a manufacturers representative for the last 25 years. These kits answer the needs of operators who are looking for cost-effective digital solutions that can impact their business operations from Day 1. This saves significant diagnosis time, results in higher energy output, and lets operators fix the problem themselves quickly or inform the OEM to address the problem.

As a result, engineers can configure, change, and build any other type of analytics inside NarrativeWave for maximizing productivity and assessing performance. Instead, every night I had to settle for watching my favorite television meteorologist use his magic marker to draw fronts on the weather map, and listening to the constant recorded weather loop on my NOAA weather radio.

How far the weather industry has come! Technological advancements in the industry are truly a significant boon to the renewable energy professional especially during a time when volatile and extreme weather has become the norm, and will be for the foreseeable future. More targeted and useful weather information is available for decision making purposes.

The general public was first introduced to weather models by their weatherman, during the local on-air forecasts. Compared to those early days, the current data dump can seem overwhelming especially when you try to make sense of the spaghetti plot of 15 different hurricane tracks, each depicting a different solution. A major tool for renewable wind energy professionals is the prediction of the lightning threat. Updated every hour, and extending to 18 hours into the future, this forecast depicts the coverage and intensity of lightning events.

For example, an expected afternoon of high lightning activity may warrant a reschedule of the planned gear box job. Additionally, smarter planning through review of lightning predictions can result in safer work conditions for your employees. Commercial solution providers are introducing intelligent displays of these forecasts, making it easier and faster for renewable energy professionals to leverage this information, and make smarter decisions.

Additional value from the HRRR model forecasts include radar reflectivity and hub height wind forecasts; these variables are produced every hour. You know the radar gun that state trooper used to pull you over for speeding? The same technology is used in all National Weather Service Doppler radars.

The upgrade – Dual Polarization radar – produces horizontal and vertical pulses, which gives meteorologists a better handle on the size and shape of the target the radar is seeing.

Ice and snow are major concerns to the industry because both can have a significant impact on wind production; ice and wet snow can accumulate on turbine blades, creating extra load and cutting generation.

Heavy loads can cause turbines to shut down, leading to complete production loss. Dual Polarization radars can even detect very light precipitation like freezing drizzle and freezing mist which, when present over a prolonged period, can also impact turbine performance. These satellites can collect three times more data, at four times improved resolution, and cover the planet five times faster than their predecessors.

Both satellites will allow meteorologists to deliver more accurate forecasts and analysis, and allow turbine owners to better access hazards impacting their operation. Because these satellites update as frequently as every 5 minutes – hurricane hunters can only fly into the storm a limited number of times per day, to collect information. Most of you reading this article are not meteorologists; you need to check what the experts say. Similarly, renewable energy professionals need to rely on their commercial providers to deliver the latest technology in clear, easy to digest formats in order to make fast, accurate decisions that benefit the bottom line.

Marty has 30 years of weather industry experience, including roles as a Meteorologist, Product Manager, and Sales Professional. In Houston, we will take the next steps forward to powering that future, together!

Wind farm operators make every effort to maximize turbine production, but they often face maintenance issues that disrupt operations. Battery-based emergency pitch control systems can be a leading contributor to turbine downtime and maintenance cost. Site managers often spend additional budget dollars performing unscheduled maintenance to address the issues associated with batteries, including degraded performance in cold and hot weather conditions, battery voltage faults, and additional turbine climbs to replace failed battery components.

Retrofitting existing pitch systems with ultracapacitors, however, will translate into higher reliability, longer life, less maintenance, and overall improved turbine operation. Ultracapacitors, also called supercapacitors, are high-power energy storage devices that store charge electrostatically as opposed to the electrochemical process in lead-acid batteries.

As a result, ultracapacitor technology provides higher reliability; systems do not require scheduled maintenance for 10 years or more, pitch battery maintenance is eliminated, and wind farm operating efficiency improves. For remote turbines exposed to extreme heat or cold environments, the electrostatic energy storage method of ultracapacitors make them an excellent choice. As a result, continual operation at frigid temperatures can render the battery ineffective in executing an emergency pitch.

Even with environmental conditioning heaters and fans , battery-based systems still www. Batteries perform best when applied for long-term energy storage requirements in more mild environments. In addition to vulnerability in extreme temperatures, batteries are often the source of pitch faults reported by the SCADA supervisory control and data acquisition system. This fault may appear during a battery load test, during battery charger failure, or when cold weather affects battery system performance and the battery fails to charge.

If a fault cannot be resolved remotely, wind technicians must climb the turbine to perform diagnostic inspections. Climbs uptower present safety risks to the technician, and are costly in terms of maintenance hours, complexity of the process, and lost energy revenue due to downtime. To overcome the challenges with lead-acid batteries, wind farm operators are retrofitting wind turbines with ultracapacitors as a much more reliable energy storage alternative.

Existing batteries are replaced with ultracapacitor storage modules, considerably simplifying the backup system. Once the ultracapacitors are installed and fully charged, subsequent recharges are completed in a few minutes. Often, site personnel must wait for batteries to recharge for approximately 20 to 30 minutes before the pitch process can complete. The fast-responding power and charging capability of the ultracapacitors recovers valuable time. In addition, ultracapacitors provide quick, high power, even after long stretches of non-use.

This is a performance advantage compared to batteries, which often have failures after stretches of idle time. Ultracapacitors are available as form-fit-functional replacements for battery pitch systems, and do not require modifications to the turbine hardware.

Current ultracapacitor-based retrofit systems include an integrated charger and communication interface, so that initiation of ultracapacitor system check, voltage, and temperature are reported to the turbine SCADA system.

Ultracapacitor retrofits do not require extensive technician training for installation. Ultracapacitor-based energy storage reduces the high number of hours spent maintaining and troubleshooting batterybased systems; this reduces the cost of additional turbine climbs performed to address battery system issues.

Technician hours are saved, and turbine availability and operational efficiency are increased. Further, consumable lead-acid battery and charger replacement parts are no longer needed, nor are the complicated battery storage and disposal processes. In order to remain competitive with other power generation sources, wind farms must harness the most efficient technologies. While batteries are the traditional energy storage technology for pitch control systems, they present challenges with cycle life, reliability, and flexibility in extreme temperature conditions.

Replacing end-of-life or failed battery parts is a time-consuming and costly process that can be avoided with ultracapacitor energy storage systems. Wind farms that have retrofitted existing turbines with ultracapacitor energy storage experience streamlined operations, more turbine uptime, and greater overall efficiency. Joshua Hitt is senior product line manager at Maxwell Technologies, a manufacturer of ultracapacitor energy storage solutions for pitch control, with over 67, wind turbine installations worldwide.

Enerpac announces the availability of its LG-Series Lock-Grip Pullers for a simple, safe, and cost-effective way to remove shaft-mounted parts. Both mechanical and hydraulic pullers are offered to suit application requirements.

The LGH-Series Hydraulic Lock-Grip Pullers provide the same safety and ease of use as their mechanical counterparts, but the pulling force is applied by a standard 10, psi hydraulic cylinder. The convenient adjustment handle simplifies the position of jaws on application and increases speed of operation, while the locking mechanism helps prevent jaws from slipping off application while pulling.

The spreading width on jaws enables use on thicker objects. The LGH-Series Pullers are also available as master sets: complete kits which include accessories designed for pulling limited access applications. Hybrid towers for high hub heights With its Hybrid Tower 2. The optimized tower concept enables hub heights of up to m and makes the wind energy plants even more cost-effective. Thanks to mobile manufacturing, the production of concrete elements is possible at almost any location in the world.

Within that sphere, upward streamers are eliminated, excess current is drained to the Earth and the development of lightning is prevented. Clir Renewables has released a new software feature which detects icing on turbine blades and measures its impact on performance. Clir developed a solution to automatically detect icing and quantify the associated losses.

The algorithm uses a probability analysis approach to flag deviations from historical, turbine-specific power curves, based on site-specific climatic conditions and historical icing events. The icing events are automatically flagged to the user as a part of their standard system, including the losses related to the events, which enables users to make informed decisions on how to proceed. Based on the results from the algorithm, Clir can make recommendations for optimization when the wind farm is experiencing icing.

As part of this optimization work, an evaluation of any installed ice detection and mitigation system is undertaken, and the results are also useful for the evaluation of available third-party alternatives.

Make your condition monitoring data work for you Smart automation not only increases turbine efficiency, but also helps to structure and connect the ever-increasing masses of data involved. Regain control over your turbines with CMS and start planning for your tomorrow. Condition monitoring systems CMS equip turbines with sensors that continuously monitor vibrations across the drivetrain at key locations from the main bearing to the generator. As components begin to wear and degrade, very specific patterns appear within the vibrations which are acquired by the sensors and identified by the CMS unit.

In near real-time, these patterns are analysed to localize the defect, diagnose the issue, and assess the severity. With this knowledge, operators can then plan targeted maintenance activities around an optimal schedule low wind speeds, multiple repairs, etc. They are easy to retrofit, control integrated and userfriendly.

Behnke concurred that the testing company has been running tests at full tilt since adding the equipment in early March. Behnke explained that getting timely results on the pricy material of liquid AC in a mix design is a driving factor in design and control of HMA projects.

GTR offers the advantage that it makes pavements less prone to both cracking and rutting. An HMA pavement needs to be strong enough to resist rutting under traffic but flexible enough to resist cracking caused by thermal and other stresses. Each property, rutting on one side and cracking on the other, can be assessed by S. The net effect of rubber, when used properly, is to stiffen the mix without sacrificing flexibility. In my opinion, the one that correlates to field conditions the most and is the most repeatable is the DCT.

Behnke explained that the Asphalt Analyzer PG model is important to the use of these new mixes because of the ability to separate out the rubber and confirm contents. Every process is a little bit different. Technicians can assess the new performance grade and the percentage of the mix the binder comprises with confidence. For example, the binder trapped inside absorptive aggregate or aged fractionated RAP gets pulled out of the aggregate during the combination of centrifuge and reflux process of the analyzer.

Using vacuum pressure, rather than heat to dry back the aggregate speeds the process without the potential to break down aggregate. Testing is forging a path to assist agencies in obtaining high quality, high performing pavements.

Whether a sample to be tested comes from a S. Proper lab accreditation and adherence to test standards are critical. American Asphalt Co. One is a 5-ton Stansteel batch plant. The other is a TPH Dillman duo-drum.

Putting the two on the same property made perfect sense from a permitting, footprint and cost standpoint, and inspired the intriguing idea of feeding both plants from one cold feed system. Serve the Customer American Asphalt Owner and President Bob Brown has performed the various jobs at the asphalt plant that his employees are required to do, thus he is aware of what his employees need when it comes to getting the job done right.

When I started, the previous owner stayed on and showed me how to operate the plant. So I have a real appreciation after running the plant, running the loaders, charging the bins, welding, wiring, fixing. I know how hard it is. I know how hot it is….

Jennings made a point of stressing that the team added the 5-ton batch plant with tons of storage capacity to the Burlington site and modified it to include a fifth hot bin to accommodate additional mix designs for larger customers while still providing commercial mixes that smaller and mid-size customers request.

The bins are supported by formed legs and have double structural stiffeners to support the walls against the extra weight and pressure from the aggregates. Each side of the bin has a custom designed, heavy duty radial gate to allow for consistent flow. The feeders are equipped with a direct drive 5 horsepower motor and gearbox to deliver consistent power to the feeder without having to deal with belts, sheaves and pulleys.

All the feeders are equipped with variable frequency drives for optimal performance on all the mix requirements. The Dual Bin System is outfitted with two inch by foot collecting conveyors, which feed the materials to both plants you see here. By adding a fifth hot bin, we can accommodate intermediate and top mix designs for our larger customers as well. Reliable Asphalt Products also re-engineered the dust entry points and added a custom flop chute under the tower to feed the asphalt into the.

We also upgraded the hot oil system and added two additional AC tanks. We also added a new control system, which allows the plant team to take advantage of the latest plant operating technology. To make their luxury product available to more customers, the team at American Asphalt looked at adding another plant to its assets.

It came back to where it would be more financially responsible to stay here [Burlington site]. We would also add only a couple more personnel instead of adding the five or more people another full plant and site would require.

The American team went with a dual feed system that allows both plants to use one set of bins. The RAP Dual Bin System is comprised of eight foot by foot cold feed bins that are partitioned in the middle to allow for two feed conveyors on the bottom of each bin.

Jennings said that also gives them room to have an extra bin or two in the event of emergencies. American Asphalt recently added the 5-ton batch plant with tons of storage capacity to the Burlington site and modified it to include a fifth hot bin to accommodate additional mix designs for larger customers while still providing commercial mixes that smaller and mid-size customers request.

Plant Manager Chris Jennings shared that they use a single Komatsu loader to feed the system for the two plants, which also lowers their cost to produce. Decisions are focused on keeping costs down for production and the customer. With the dual feeds, each stacked bin holds a total of tons.

Fifty tons go to the feeder for the drum plant; 50 go to the batch. At this time, they use a single Komatsu loader to feed the system. One loader for two plants lowers their cost to produce, making them a low-cost provider. The ideal situation is they feed to the center of the bins. We are always looking for the latest advancements and technologies available to keep us one step ahead of our competition.

Respect, Integrity, God honoring, Honesty, Trust. Every employee is empowered to be able to make our customers feel not only important, but a vital part of our team by treating them RIGHT. By maintaining constant contact with the customer, we keep our production teams informed of the status of every job, even while the job is in progress.

The more we communicate, the better we and the customers become. We want American Asphalt Company to be the producer of choice. Under the direction of Bob Brown and management of Chris Jennings, the American Asphalt team has created a unique plant layout that will greatly. American overcame issues with both permitting and plant layout space with such an innovative design. The fact that they were able to add a 5-ton batch plant and silo system without rearranging the existing facility is amazing.

From start to finish on this project, the American Asphalt team has done a tremendous job in both planning and execution. By focusing on a plan to better serve their customers, American Asphalt has set itself up to be a leading organization in the industry both locally and nationally. Add the optional V-Pack stack temperature control system to operate in the most efficient way possible.

With new engine emissions regulations and electronic data logging rules out there, advanced technology can either help or hinder the regular maintenance regimen. Producers have streamlined processes at the plant; contractors have nailed down best practices in the work zone. Operating a commercial vehicle means a state or federal inspector can stop you if they notice something that appears unsafe.

This behooves you to perform routine maintenance for best and safest operation in between your mandatory periodic inspections. One of the most important items to ensure is working on your truck is the backup alarm. Many companies have instituted the policy that a haul truck with an inoperative backup alarm will not be allowed on a job. This means an independent driver could show up with a load of material and get kicked off the job, making him financially responsible for 18 or so tons of cooling mix.

To track maintenance activities, drivers and mechanics have the help of modern technology. Even before large original equipment manufacturers OEMs joined forces to standardize data points, they were developing telematics to gather information on the way engines run, to detect faults in equipment, to schedule maintenance actions, to streamline machine safety, to monitor emissions controls, and to gather data for fleet management. For instance, the team at Volvo Construction Equipment has telematics packages standard on 7 articulated haulers, 23 excavators, 11 wheel loaders, and as an option on two pavers, 2 soil compactors, 4 asphalt compactors, 4 compact wheel loaders and 8 compact excavators.

Then the Volvo Trucks team has the Gateway telematics system to monitor and gather data for commercial vehicles. Other OEMs have recently released telematics solutions for on-highway trucks. In March, Caterpillar announced its on-highway truck fleet solution complementing telematics that are already standard on their construction equipment. Back in the mids, OEMs recognized that many contractors have mixed fleets, which meant the end user had mixed data coming in on different types of screens.

Different machines were failing to talk to one another in different languages. That had to be reconciled some way. By Feb. Fleet managers know there are more data points than the six listed in this paragraph, and OEMs kept working to make the standard more robust for the end user. This gives contractors and fleet managers confidence that the data-monitoring across the fleet is gathering, interpreting and delivering information in a uniform manner.

No matter what tier level your engine is, you are responsible for keeping it, and the components surrounding it, in top working condition. Check the belts and hoses on a regular basis, too. Make sure the air cleaner indicator gives you a good reading. Consider the new after treatment systems available now. You want to monitor whichever system your engine manufacturer uses and perform basic maintenance as the OEM recommends. While you can take care of routine cleaning and checks on your own, error codes indicate problems that may require professional help.

He mentioned onboard diagnostics OBD and liability. If you receive a warning light or fault code from your OBD regarding your Tier 4 engine, you may be breaking the law if you make the repair yourself. Piech explained that changing the way an engine runs has both safety and environmental impacts.

Additionally, if there is an error code flashing on the display, your best bet is to call the nearest servicing dealer so they can diagnose and fix the problem. Think about oil changes for a moment, because even this. If you pick up the FA-4, it is designed to work optimally for the engines. Some of the goals of upgrading from the former CJ-4 oils to the PC category are to protect engines no matter what level of shear stress the oil will undergo in the engine, to protect against oil breakdown due to oxidation under higher operating temperatures, and to safeguard fuel economy.

This will require changes in engine oil composition, so they can withstand more heat without sacrificing engine protection. The new FA-4 engine oils will be offered in lower viscosity grades and are designed primarily for next-generation engines to help maximize fuel economy without sacrificing engine protection.

These FA-4 oils may have limited backwards compatibility, and would be labeled as such. If you feel the need to spend seven or eight minutes on this, Chevron has prepared a series of short videos at www. Part of your daily, pre-shift walkaround should include looking at this sign to ensure it is clean, legible and in good repair. Keeping the haul truck in top notch condition does more than keep you in compliance with the DOT.

Each piece requires maintenance for optimum performance. Start at the top. You want to inspect the tarp—or canopy— each day to ensure it has no rips or tears. Look at the mechanism that lowers and raises the canvas to ensure it moves smoothly and completely.

This leaves room for wind to whip in and cool the top of the material into a segregated shell while you drive from the plant to the job site. This system runs on two cables that unroll and retract the canvas along rails, forming a lid on the truck body when closed.

Telematics is, at its core, machines talking to machines. Photo courtesy Roadtec, Chattanooga. While inspecting the tarp before your shift begins, look into the truck bed.

Take the time to pick out plastic wrappers, soda cans and anything else that has gotten in. Anything you see in the bed of the haul truck will get covered with mix and then will get carried into the hopper of the paver. As the haul truck driver, you can stop that financial loss with just a few minutes of cleanup during your preshift walk-around. Another way you can make your vehicle appealing to the paving crew is to make it com-. That leads to a potential mess each time trucks charge the hopper—giving laborers extra shoveling to do and an extra repair for the mechanic.

Your truck will be more compatible with the paver if you can get the mud flaps out of the way, as well. Each individual state department of transportation DOT has different requirements of haul truck mud flaps— splash guards.

Then look into systems for easily lifting the flaps out of the way. When you back the truck to the paver, you stop before making contact. When the paver operator moves the paver forward and brings the push rollers into contact with your vehicle, the push rollers are to touch the back wheels of the haul truck. If the mud flap is in the way, the push rollers now have the opportunity to deliver a jerking motion as the tractor moves forward.

This will cause segregation in the mat. The push rollers also have the opportunity to tear the mud flaps. This means a repair for you later and possibly a chunk of polyurethane in the mat, which is another quality control problem.

The push rollers also have the opportunity to leave asphalt mix on the mud flaps, which means more cleaning for you at the end of your shift. None of those scenarios is an efficient use of time or materials. Instead, look for a system that will let you press a button in the cab to hydraulically lift the mud flaps when you enter the paving work zone.

Or use this idea from Murray. He has extended the outer flaps of his rig from heavy duty chain. The chains keep the flaps hanging at the proper height for his DOT regs, and allow him to physically place the flaps on the fenders to keep them out of the way while he discharges the load. As you can see, haul truck maintenance goes beyond changing fluids and filters on a regular basis.

It goes beyond handling the big emergency repairs that crop up. By performing daily inspections and regular maintenance, you keep your vehicle in compliance and enhance your ability to contribute to a quality paving team.

Today, Coastal Bridge employs between and people in the asphalt division of the company, which also has bridge, industrial and commercial divisions. Its four asphalt plants—all Astec double drums running tons per hour—are located in Baton Rouge, Convent and Lafayette, Louisiana, and in Tampa, Florida.

Roughly 70 percent of the , tons of mix it makes annually gets laid by its four laydown crews on projects ranging from parking lots to interstate highways.

In the spirit of expansion, Coastal Bridge bought the Tampa plant just two and a half years ago, hoping to add another , to its annual tonnage.

And, in the near future,. Coastal Bridge also expects to add a fifth crew, based in Tampa. And, in , Coastal Bridge purchased its first Stansteel Accu-Shear Blending System to continue its history of continuous growth and improvement. After experiencing a slew of unexpected benefits, in addition to the ability to foam its mixes, Coastal Bridge purchased a second Accu-Shear for one of its other plants. But, the road to this point was paved with plenty of issues—no pun intended. When Coastal Bridge first began foaming its material eight or nine years ago, their foaming gun was a pain.

The AC going through would often clog the water ports. These conversations just so happened to occur around the time Louisiana agreed to allow latex-modified asphalt cement AC to replace PG polymer modified AC.

But, it would still be a while before Langley would get the equipment he now knew he wanted. Instead, Coastal Bridge purchased an inline blender.

So, the company tried a different, fluted blender and placed it on its Lafayette plant. Although it worked much better, it would use more latex to obtain the same values—1. So, finally, the company purchased the Accu-Shear. The tests were consistent, the whole nine yards. It was great. Its Tampa plant uses the foaming system that came with its Astec plant. Langley estimates that foaming has saved Coastal Bridge between 8 and 10 percent a year in fuel costs and has substantially reduced its carbon footprint.

By using the Accu-Shear, Coastal Bridge also saw the amperage draw on its slat conveyors decrease when running a dynamically foamed mix. Langley also discovered he could keep foamed mixes in the silo longer and that the material released and flowed better. Generally, Coastal Bridge limits the range it hauls mix to 80 to miles away from the plant. But, with properly foamed mix allowed to be made at a lower temperature, Langley reports they can go up to 30 percent further without reductions in temperature.

Langley reports seeing increased compaction on foamed mix, even when the crew uses the same roller, in the same manner, with the same number of passes. That means the crew can reduce its compaction effort by up to three passes, in some cases.

That means the crew is moving faster with fewer passes, an increased paver speed, and is laying more in terms of total tons by the end of the day. Coastal Bridge is one of only a few companies using liquids modified with ground tire rubber GTR. Coastal Bridge acquired the plant in Tampa, seen here, only two years ago. It plans to significantly ramp up production at the plant and establish a fifth paving crew in Tampa.

After noticing its many benefits, the company purchased a second Accu-Shear for another of its plants. In Louisiana, Langley said, the state wants to see a reduction in temperature if a plant is foaming its mix. However, the lower limit is typically degrees. Coastal Bridge runs at degrees, for a bit of added flexibility. That extra bit of heat also had a positive impact on the mix quality. That requires suppliers to write a letter confirming their materials can achieve those standards, but Langley said suppliers are often hesitant to do so.

Rouge plant. Coastal Bridge performs nearly every type of test for virtually any specification, Langley said. It has labs in each of its plants, but its main lab is in the Baton Rouge plant.

With the Accu-Shear, users can buy them with a handful of ports to inject several different liquids at the same time, or simply as a water foamer. Langley is even thinking about getting a second Accu-Shear for the Baton Rouge. First, he wants to better integrate antistrip into his mix. Louisiana requires plants to use a minimum of. Langley said most plants use an amino-based antistrip.

This installment looks at the roof of the haul truck cab. The paver operator, dump man and screed operators are tasked with watch-. Their attention is typically focused downward, not up. If the paving train moves forward at 20 feet per minute, the paver may push the truck, with its body in the air, right into a mature tree branch or—worse—into live wires. The downtime involved when a truck gets tangled up in wires amounts to thousands of dollars at best, serious injuries at worst.

Other crew members should not approach the truck and should not attempt to untangle wires. A member of the crew will contact the utility company, of course, but will also contact emergency responders to assist. Trying to exit the cab before the utility company has ensured power has been cut off to the affected wires can result in serious injury or even death. Truck drivers still need to be on the lookout for dangers overhead. When independent haul truck driver Steve Murray wanted extra safety, he in-.

Construction Angels Inc. Our goal is to assist the family at the beginning of their grieving process with hopes to provide them with a sense of comfort, both financially and emotionally. Construction Angels wants to make an everlasting impression and impact within the industry, one family at a time. The third annual event was held at the Bergeron Rodeo Grounds in Davie, Florida, April 15, and featured an all-day battle of the best chicken wings and sauces from at least 14 of the best restaurants in the area with celebrity judging.

Live rock and country bands entertained a record-setting audience. Because Construction Angels is a national organization, Ronyak seeks ways to expand its good work beyond the headquarters of Florida. A Michigan contractor, Giannetti Contracting Corporation in Sterling Heights, is fundamental to that recent piece of success.

Construction Angels also provides grief counseling to those families who have lost loved ones in our industry. We have partnered with various organizations and charities to ensure Construction Angels is able to assist these families during tragic times. Our goal is to operate in every state and to assist these families around the United States. To help the organization help more families in their most dire time, everyday workers can get involved without traveling to Davie, Florida, for the annual WingsFest.

Ronyak has another, easy way workers can pay it forward to help one another. By providing the form to your human resources department, you authorize the payroll department to deduct a dollar or two—or whatever you are comfortable donating—from each of your paychecks.

The way Ronyak explained it makes perfect sense. That may not seem like much to the person doing the donating, but it adds up for the Construction Angels and for the families who suffer a tragedy down the road. At press time, Construction Angels was hard at work preparing for the next fundraising events in the four regions in which it operates, and working to incorporate offices in additional states.

Eight years later, what was once an interesting idea is now a standard practice across most of the nation. The construction season survey results were released in March , and NAPA is currently surveying the industry about use of these technologies and materials during The first survey found that barely 43 percent of U.

Since that time, growth in warm-mix production has increased dramatically, although the adoption curve has begun to plateau See Figure 1.

During the construction season, some Seventy-eight per-. IS is now available. To download a full copy of the survey, visit www. The numbers are a dramatic percent increase in WMA tonnage and a percent increase in the use of WMA when considered as a percent of total tons since It is also a greater than 5 percent increase in tonnage over the construction season and a 1.

State departments of transportation remain the biggest customers for WMA. Nearly For other public agencies, such as cities and counties, 34 percent of the tonnage was WMA. For commercial and residential customers, the percentage was slightly higher at Figure 2 shows WMA use as a percent of total asphalt mixture production in each state.

For additional product information and services please visit : www. Figure 2. Of the available WMA technologies, plant foaming remains the most common, being used for 72 percent of the WMA produced in The use of chemical additive technologies reached an all-time high. Additive foaming and organic additives make up the remainder of the market. The percent of WMA produced with additive technologies has grown significantly since when they made up less than 5 percent of the WMA technologies used.

In total, companies representing 1, plants participated in the survey. Responses came from 48 U. Kent Hansen, P. Audrey Copeland, Ph. Carter Ross handles communications for the association. For over 30 years, Hotmix Parts has supplied all types of equal to or better than original equipment parts in equipment. Most important, we have the experienced personnel and technical know-how to help support and improve your plant and make it run better.

Every brand and every type of asphalt plant can be improved and upgraded. Innovative employees know how to make a job flow more smoothly for a company. For Lindy Paving Inc. Project Engineer Kyle Monceaux and Senior IT Business Analyst Steve van Vliet reached out to Robert Carroll, the vice president of commercial initiatives for Nearmap, a location content provider specializing in high-resolution, aerial imagery, to set up a mapping technology within the app.

Now the new app helps Lindy Paving lower expenses while increasing revenue. The field data collection app is browser-based and designed to increase efficiencies in communication and project management of its plus paving projects conducted each season. Created for both field and office use, the browser app replaces reams of paper maps, spreadsheets and PDF files, while allowing planners and estimators to prepare for projects without physically going to the site.

In the past, the company had to send a field engineer to walk the site and take pictures of problem areas. General consumer grade technology such as Google Earth could not provide them the detail that project managers need-. We developed our own camera and data collection system. In future versions of the app, Lindy plans to build in tools allowing calculations and drawing directly on the Nearmap imagery to determine exactly where objects will go on any given project.

For example, one of their clients — a large utility company — works with Lindy to repave roads and sidewalks of the hundreds of infrastructure repair locations they work on each year. The aerial images show Lindy crews the exact locations of their projects. Planning is something Nearmap can assist clients with thanks to the regularity and frequency of flights and image collection. Carroll said the flights take place several times a year, which means pictures are updated on a regular basis, keeping images current.

So we can see and track changes over time. Lindy Paving Inc. Lindy has consistently delivered award-winning asphalt paving and product manufacturing. Hayes awards and has continued to attain Quality in Construction awards since then. The company boasts five asphalt plants and a terminal in the state to serve its own paving crews as well as customers.

The drum mix plants are set up to produce any mix design for commercial, municipal or state projects, including warm-mix asphalt when needed.

You can approach any one of their executives and sit down to discuss an idea.
