Employee Engagement is Vital to Retaining Workers

T

he labor shortage in the road building industry keeps many asphalt contractors awake at night. Because it’s so hard enough to find good workers, it’s vitally important to keep the ones you already have happy and engaged.

According to the article, “Why is Employee Recognition Important?” at Bonusly (bonus.ly on the web), disengaged employees cost businesses an estimated $550 billion last year in the United States.

Staff recognition is a highly effective and proven strategy for improving employee engagement. A well-implemented staff appreciation program has the power to impact many aspects of your business from morale to productivity to retention. After all, employees whose work is recognized and appreciated are more apt to stick around.

There are many ways to recognize employee contributions. According to Bonusly, there are two main divisions: Top-Down and Peer-to-Peer.

Top-Down recognition involves a supervisor witnessing and recognizing the contribution. It can take many forms: • Years of Service Awards can be given at specific intervals or milestones.

• Employee Appreciation Days can be celebrated with cookouts or small office parties.

• Bonuses can be awarded annually, quarterly or “on the spot.” An “on the spot” bonus — usually $50 or less — is used to thank workers and recognize

8

exceptional productivity, safety or efficiency.

Peer-to-Peer involves both managers and coworkers. These might include: • “Gold stars” or other mementos that can be traded in for real-life items/ prizes, including extra vacation days • Microbonuses, like “on the spot” bonuses, can be given the moment a valuable contribution is made by an employee. These are typically small financial amounts and can recognize an employee without drastically altering the employee’s compensation.

The types of awards are important, but it’s also important to be timely.

Don’t wait to recognize an employee for being exceptionally productive that one day months ago.

Consistency is important as well. If Joe gets a microbonus for wearing all his safety gear every day for a week, Fred should get it too.

Customize rewards to highlight your unique company culture.

Employee recognition is crucial to retaining workers. Let me know if your company has some exceptional employee engagement strategies by emailing me at lcleaver@acbusinessmedia.com.

TECHNOLOGY MATTERS |

BY JESSICA STOIKES, ASSOCIATE EDITOR

Finding SMARTER Ways to

Monitor Roads New technology in our vehicles and smartphones can help cities better manage trouble spots on roadways

W

e all know that one potholeridden roadway in our neighborhood that we try to avoid at all costs. Your local municipality, however, may not even know that street has issues that need to be addressed.

Because of this, cities are looking for ways to direct street improvement resources more effectively, given the limited resources to monitor streets and lack of funding for repairs.

16

Cities are starting to invest in digital monitoring to replace traditional laborintensive techniques, enabling more frequent and accurate assessment of infrastructure quality. These digital methods primarily fall into one of two categories: vehicle-based monitoring systems, which collect data via an array of sensors attached to a vehicle (usually very expensive and owned or contracted by the city), and smartphone-based monitoring

Land Rover is researching a new connected car technology that will allow a vehicle to identify the location and severity of potholes. It will then share this data in real time with other vehicles and with road authorities to help them prioritize repairs.

TECHNOLOGY MATTERS systems, which leverage built-in smartphone functionality to gather road data.

VEHICLE-BASED MONITORING Vehicle-based monitoring systems outfit vehicles with a variety of sensors to continually track the path they travel and provide a profile of the street conditions encountered, creating more consistent and objective data than is collected in traditional road surveys.

The StreetScan system, developed

by Northeastern University, is just one example of these scanners that can be mounted on any city vehicle. Using GPS, radar, microphones, cameras, tire pressure sensors and an accelerometer, StreetScan collects a wealth of data about street condition, material and points of concern.

“Researchers are experimenting with the built-in GPS, camera and accelerometer functionality in smartphones to help monitor roads.”

The downside is this equipment can cost over $50,000 per vehicle, a cost most municipalities can’t justify given that they can’t even afford to repair the roads they monitor.

So city officials in Cincinnati had an idea. They partnered with local firm INFRAME to compile a comprehensive picture of their street conditions using a PaCE (Pavement Condition Evaluator) van equipped with cameras, lasers and other monitors – similar to the StreetScan setup – which identifies road surface issues and provides georeferenced images with a one millimeter resolution for the city to use to direct its efforts.

Using funding from their flexible Capital Acceleration Plan, the city hopes to improve consistency in their process,

18

build a safer road network and to save money in the long run by proactively addressing road needs without requiring the city to purchase the equipment itself.

AUTOMAKERS HATE POTHOLES TOO Besides ruining your driving experience, potholes are also responsible for many accidents and costly repair bills. This is why automakers are even starting to get into the pothole monitoring game.

Today, research vehicles at Land Rover are being installed with technology that allows them to identify the location and severity of potholes and broken manhole covers and subsequently adjust the suspension in milliseconds.

Researchers working on the technology say it will be possible to share this data with other cars via the cloud so all drivers will get a warning about dangerous potholes, allowing them to slow down and avoid the danger. This could mean the potential for punctures, wheel and vehicle damage, as well as road accidents could be reduced. The system would also alert road authorities about the potholes.

CROWDSHARING DATA VIA SMARTPHONES While in-vehicle based monitoring may be a few years in the future for most of us, drivers today likely already have one piece of equipment in their vehicles that can already keep track of potholes, their smartphone.

Other cities and researchers have experimented with monitoring street quality using the built-in GPS, camera and accelerometer functionality of smartphones. These monitoring systems are ideally placed on city vehicles that already travel the city daily (such as public works trucks), or used to assess street quality through crowdsourcing, much like Waze’s traffic monitoring.

In a 2015 pilot, Carnegie Mellon researcher Christoph Mertz partnered with the city’s public works department to install smartphone cameras in city vehicles to capture images of the streets in Pittsburgh, PA. Paired with GPS data and fed through a computer algorithm,

these images are classified according to the types of road surfaces and the damages pictured, something the city hopes will help them identify sections of street that need the most urgent attention.

Similarly, Canadian startup TotalPave provides cities with a smartphone app that records overall road quality (measured via the phone’s accelerometer) and manually tracks individual issues, such as potholes. Initial findings report that the smartphone data is within 10% of the International Roughness Index (IRI) numbers reported by expensive vehicle monitoring systems.

TotalPave, which costs cities little more than a smartphone, plans to start with 38 cities and expand from there, eventually targeting more than 13,000 North American cities.

When used in vehicles on daily routes around a city, apps like these can collect a wealth of data while requiring minimal time or effort from city employees and can eliminate many single-purpose street survey efforts.

However, the idea of crowdsourcing street quality data from city citizens holds the potential to create an even larger, richer dataset.

Boston, a frequent early adopter of civic technologies, launched Street Bump in 2012. Pioneered by the city’s innovation office, New Urban Mechanics, this free app is Boston’s take on smartphone-based street monitoring and is open-sourced, so other cities can use and improve it.

By aggregating the experiences of hundreds or thousands of drivers who traverse the streets of a city, researchers and city officials hope to uncover insights about road quality which would otherwise require intense labor from city workers. With dozens of phones reporting poor conditions on a road each day, these once-hidden problems become readily visible to city officials and can be prioritized for repair. AC

TECHNOLOGY MATTERS

CONNECTED WORKSITES: Start Making More Money Here are the benefits of connecting worksites digitally, how to get started, and how jobsite technology will impact your people

W

hat construction equipment manufacturers and hardware/ software developers envisioned as a more productive, profitable digitally driven worksite exists — now. With today’s technology you can clear a commercial site, lay the groundwork for a housing development or build a section of road from site assessment through project management, evaluation and straight to billing without creating a single piece of paper.

Digital technology enhances what you’ve always done by making your operation highly accurate, less wasteful and more cost effective. Now’s the time to get started or risk being left behind.

Companies who fall behind will face greater challenges to their profitability than those who engage early.

Time to stop talking and start making more money.

3 BIG ADVANTAGES TO TAKING WORKSITES DIGITAL • Manage your equipment costs With the introduction of the Association of Equipment Management Professionals (AEMP) Telematics Standard, more systems are working to give you access to mixed fleet data such as equipment location, fuel consumption and operator behavior. From your laptop or phone, you can see where your equipment is working, how much fuel it’s consuming and how productive it is. Data access gives you total control over maintenance and repair needs. Downtime is minimized and the lessons learned from each job make you more effective on the next.

20

• Make the most from your fleet The more connected your equipment and crew is, the faster you can identify where the problems are and course correct. Do you need more equipment on the site?

Maybe you don’t need as many machines as you rented. And because you have the ability to track the amount of material moved that day or week, you can track productivity and where you are in terms of what you bid for the project.

• Take operators to the next level Equipment that offers machine control and/or automatic functions will help operators make a positive impact on your bottom line – quickly. You can expect to be able to reduce rough-grading costs, slash finish-grading costs and place materials more accurately and consistently.

Being able to control your material is a huge advantage. Your operators are making a lot fewer passes to get on grade.

Technology allows your operator to manage the task and the material, not just the machine. It helps a decent operator become outstanding and it helps an inexperienced or unskilled operator to become adequate. As a result, it can help you overcome any shortage of skilled labor by expanding the pool.

BEST STARTING POINT FOR WORKSITE TECHNOLOGY? The good news is that you don’t have to jump in on a grand scale to see the benefits that technology and connectivity can bring to your work. For example, you can take advantage of your telematics data-feed capabilities as soon as you activate the feeds and log into a reporting interface, like VisionLink.

If you’re running a smaller fleet, you

will likely be more interested in machine technologies that deliver rapid increases in productivity. Those investments are usually recovered relatively quickly and can generate more revenue for additional technologies. Larger fleets or fleets working multiple projects simultaneously will want to create a technology plan based on existing data capabilities and most cost effective equipment and technology pairings.

Site specialists recommend you concentrate on what you’re trying to do, the type of machines you use and what seem to be your biggest problems. Be realistic about your limitations and areas in the organization where you’re not being as productive as you want to be or are potentially losing money. Focus on how technology can help you with these.

TECHNOLOGY EMPOWERS YOUR PEOPLE Taking your worksite digital means the decisions on site are not going to be made exclusively from the office. It means you believe that your people are capable and committed. By building more connected worksites, more information will be delivered to the right people at the right time, so they can make the decisions they need to get the job done right.

As more machines are connected on the worksite, the better efficiency, accuracy and productivity can be measured.

The primary goal of the digital worksite is to make the work less complicated, margins healthier and lives better. AC

Fighting Fire with a

PLAN

A step-by-step guide to preventing fires at your asphalt plant

F

ires are usually unexpected and can be devastating. For your asphalt plant, it is essential to have a fire safety plan in place.

A comprehensive plan not only provides information regarding the procedures to follow in case of an emergency, but also informs your employees and occupants of your commitment to their safety.

There are many ways a fire can start at your asphalt production facility. Bag houses, for example, are connected to the mixing drum and designed to capture pollutants before they enter the atmosphere. These particles contain liquid asphalt, a combustible material.

When a spark occurs an explosion in the bag house could result Bob Petras, with the Inland Marine, Risk Control division of Travelers Insurance, recounts one example of a fire at an asphalt plant.

“There was one instance where there was an explosion in a company’s asphalt storage elevator,” Petras recalls. “Over the course of a day, during production, material built up at the base of the elevator. To be ready for the next day, the debris that accumulated needed to be cleaned out.

“The company sprayed diesel fuel at the base of the elevator to clear the material,” he continues. “This is not an uncommon practice for an asphalt plant and sounds fairly simple. But in this

36

instance, the drum was still hot and the debris in the base of the elevator was still around 300 to 325 degrees.

“When you put diesel fuel that has a flash point of 165 degrees in an area where the temperature is 300°, any ignition source present can result in an explosion.”

FIRE HAZARDS AT ASPHALT PLANTS Some of the major causes of fire at asphalt plants can be: cleaning with diesel fuel; leakage around liquid AC and oil heater lines; and not properly cleaning the area around liquid AC tanks, resulting in ponding of combustible liquids within the diked area.

Any of these can result in a serious fire from heat sources like tramp metal, uncontrolled hot work, or electrical arcing.

“At no time should diesel fuel be used as a cleaning solvent near any heated work surface,” says Petras. “In fact, many states have mandated use of only noncombustible release agents.

While this is done mainly for environmental concerns, it also eliminates potential fire hazards and occupational exposures to employees.”

Asphalt production facilities should have a formalized operations

and maintenance plan in place that is developed based on their specific site needs. This should take into account the type and manufacturer of equipment and degree of anticipated use.

“Unfortunately, in many cases, operational instructions at asphalt plants are done informally on a basis of ‘passing the instructions on’ from one operator

PRODUCTION NOTES

Elements of a fire safety plan Your fire safety plan should highlight emergency procedures to be used in case of a fire, including sounding the alarm, notifying the fire department and evacuating building occupants.

All employees/occupants and managers should be aware of the plan and properly trained on the procedures in place. The time to learn safety procedures is not during an emergency.

Elements of your plan should include, but not be limited to: • The appointment and organization of designated supervisory staff by position, with related duties and responsibilities during an emergency.

• Instructions for building occupants and staff on fire prevention methods and what to do in case of fire.

• The method of training supervisory staff for fire emergencies.

• The method and frequency of conducting fire drills.

• The control of fire hazards throughout the building.

• Floor plans that feature the type, location and operation of fire protection systems, access for firefighting and all exit facilities.

• Detailed instructions for supervisory staff on the use of any emergency equipment, such as the voice communication system, the fire alarm system, smoke control system or emergency power supply system.

• Procedures for the use of elevators and the evacuation of building occupants requiring special assistance.

• Established procedures for assisting the fire department in accessing the building and locating the fire. For large facilities, it is recommended that floor plans showing exit locations be posted on each floor.

• An accountability system that can account for all building occupants following an evacuation, including notification to the fire department of any missing occupants and their last known location.

to another,” says Petras. “When this occurs, many safety-related tasks can be overlooked, which can have serious consequences.”

Formalizing all aspects of plant operations and security is one of the best ways to minimize risks.

FIRE PREVENTION PLANS When it comes to putting a fire prevention plan in place, where should an asphalt plant start?

“It’s a good idea for plants to conduct a pre-plan assessment with their local fire department,” says Petras.

This could include evaluating key points such as: • Where combustible materials are located • How cleanup and maintenance are conducted • Where the hot work occurs • How water supplies can be accessed in case of emergency • What are the integrity of access roads It’s also smart to have a business continuity plan in place, says Petras.

“A highly effective plan will have four key components,” he says.

First is identifying the biggest threats or risks to the business. This entails understanding the risks that could leave employees, property and operations vulnerable. Companies can identify the risks most likely to occur based on historical, geographical, organizational and other factors.

Second is conducting a business impact analysis, which includes identifying the people, places, providers, processes and programs critical to the survival of the business. Consider who and what

are absolutely necessary to restore critical operations. Then prioritize the need to restore each item after the event.

The third is prevention and mitigation planning and activities to help prevent an event (such as a fire or explosion) from happening in the first place. Consider emergency response, public relations, resource management and employee communications.

In the case of fire prevention, make sure there is an available on-site water supply for firefighting, adequate portable extinguishers, master fuel cutoff controls, master electrical cut-off controls, and adequate cleared space for exits and firefighting, if needed.

There should be a formalized maintenance and housekeeping program, a formal hot-work program in accordance with NFPA 51B “Standard for Fire Prevention During Welding, Cutting, and Other Hot Work,” and clearly defined and enforced safe work practices when using diesel to clean asphalt from the various components.

Lastly, it cannot be overstated how important it is to routinely test, exercise and improve the plan.

“A business continuity plan is an evolving strategy that needs to adapt to the changes in the business,” says Petras. “To test the plan, businesses can have discussions or hypothetical walk-throughs of scenarios, live drills or simulations.” AC

FOR MORE INFORMATION There are several resources where asphalt plants can get information on mitigating fire risks. The National Asphalt Paving Association (NAPA) is a great source for controls and measures for asphalt plants. It has a variety of information and tactical advice, and even has a rating system to measure the operational quality for the plant.

Travelers’ Prepare and Prevent website has information on fire safety. “Travelers customers can access the Risk Control customer portal for detailed information on how to avoid fire,” says Petras. “Customers can also schedule a consultation with a risk management professional to pinpoint the high-risk areas for fire.”

How to Create Hot Oil Heater

HISTORY

When heat transfer issues cropped up, CW Matthews used Paratherm’s testing services to analyze its oils and keep its asphalt plants productive

C CW Matthews sent hot oil samples to Paratherm for fluid testing to help identify issues.

40

W Matthews has 26 asphalt plants in the state of Georgia, and each one has a hot-oil heater to keep the plant and the asphalt cement hot.

The company began in 1946 with one tractor and two dump trucks, when CW Matthews and two local businessmen formed it after returning from the World War II Pacific Theater. In 1954, Matthews formed CW Matthews Contracting Co. Inc., and three years later made the pivotal decision to enter the plant-mixed asphalt business.

The company continued to grow and expand over the next decades, and was involved in some of Georgia’s biggest infrastructure projects, including the $1 billion expansion of Atlanta’s freeway system, readying Atlanta for the 1996 Olympic games with the addition of high occupancy vehicle lanes on I-75, and serving as part of a threecompany consortium for the construction of the 5h Runway at Harstfield-Jackson

Atlanta International Airport, the largest public works project to date undertaken

by Georgia.

Today, the company has placed more tons of asphalt paving in Georgia than any other privately-owned company, has received numerous awards for quality riding surfaces and is consistently among the highest producing asphalt operations in Georgia. It also has the capacity to manufacture more than 5.5 million tons of asphalt each year.

“There are other construction companies in Georgia, but with our 26 locations, we may be the most diverse and serve more of the state in its entirety,” says Joe Hines, superintendent of plants with CW Matthews.

HEAT TRANSFER ISSUES Last year, Hines notes, CW Matthews was experiencing heat transfer issues at one of

its locations. The company was having trouble transferring heat, so it reached out to Heatec, the manufacturer of the hot-oil heaters and AC tanks at that location.

“We have a strong relationship with Heatec,” says Hines. “We get our

As a part of Heatec’s annual service school, CW Mattews was introduced to Paratherm who helped them identify heat transfer issues at their locations.

equipment from them, and when we have issues we're not familiar with, we trust them and the quality of their equipment and their support.

“At their annual service school, our general superintendents met Steve Beward and Jim Oetinger of Paratherm giving a troubleshooting presentation on heat transfer fluids as part of the training agenda in Chattanooga.”

After the meeting in Chattanooga, CW Matthews sent hot oil samples from its HMA plants to Paratherm for fluid analysis.

“We sent samples from plants that we thought were having issues as well as from plants where we thought the systems were running well,” says Hines.

Jim Oetinger, Paratherm's director of technology, who runs the testing, used the analyses to help with predictions, to identify issues, and to recommend which systems could use a fluid replacement, and which systems could be checked again in a year without further intervention.

“We took those recommendations back to Heatec, particularly for the unit where we had some heat transfer issues, and they came to the plant to help isolate individual parts of the circuit,” says Hines. “In some cases, they identified

www.ForConstructionPros.com/Asphalt

ACON0517_40-43_ProdCW_JL.indd 41

spots to put in new valves to help with isolating and cleaning specific parts of the hot oil circuit, for flushing right then as well as for future continuing maintenance.”

Hines says Heatec was a great asset when it came to the physical maintenance too.

“We elected not to use a chemical system cleaner because we have some jacketed lines that can be difficult to drain completely,” says Hines. “Heatec helped with the physical cleaning and draining, isolating each section, and using a vacuum truck to completely drain the old fluid.”

DETAILED TESTS FOR DECISION MAKING Hines says working with Paratherm has helped CW Matthews improve its overall maintenance planning and execution.

“The biggest thing we gained from Paratherm was information and instruction on preventive maintenance, knowledge about the heat transfer fluid and its changing characteristics with use, and how to use the information to reduce reactive maintenance,” he says.

“We'd done lube-oil type sampling before, but that didn't give us the same detail,” he continues. “Those specialized hot-oil tests provide the characteristics and information to make decisions affecting our equipment going forward.”

Hines says the company has been testing their heat transfer fluids for over a year, and now they can begin to compare results to see how things are changing.

“We're now getting into year two of an annual testing routine for each of our 26 plants,” he says. “Now we can begin to study, with Paratherm and Heatec, the ongoing changes in the fluid, and the equipment, based on the fluid-analysis history.

“We can begin to compare how things are changing over time,” he continues.

“That's preventive maintenance based on a running history, to keep the heaters and systems operating well on an ongoing basis.” AC

Parathem made recommendations to CW Matthews who took those to Heatec who came to the plant and helped the company isolate issues.

For more information on asphalt plant maintenance visit ForConstructionPros. com/12294511.

Heat Transfer Fluid Analysis Over the past 20 years, Paratherm’s technical experts have performed thousands of fluid analyses on samples of mineral oil based heat transfer fluids.

Fluid analysis reports have enabled asphalt plants to correct problems before they become expensive, avoid complete heating system failure or just sleep better knowing that the fluid is still in good condition.

Paratherm’s fluid analysis program goes beyond simply running laboratory tests that measure properties of the fluid. At Paratherm, laboratory test results become a total system analysis using their extensive knowledge of equipment and processes.

Fluid analysis can determine: • Whether the results are “normal” • Whether equipment problems exist • Whether operational issues are causing the fluid to degrade Results are reviewed with asphalt plant managers and operators, causes and remedies for any abnormalities are explained, and finally a report, which includes advised recommendations, is issued.

The result? You will know whether your fluid is “good” or “bad,” whether it’s causing problems, and, most importantly, you know what you can do about it.

Burner Tuning Begins with Control & Maintenance

L

ast issue, we talked about burner tuning and the proper tools to use to analyze the performance of your burner, and how both of these things can optimize fuel consumption at your asphalt plant.

In this column, I'll explain how precise control of the equipment and routine maintenance will go a long way to keeping your burner tuned, saving fuel consumption and your bottom line.

As a regional Hauck Burners sales center for the Western U.S. and Canada, I get to play with a lot of very cool technology. The newest lines of burners and controls are simply awesome. In February, we installed the latest version of their BCS7000 on a plant in New England.

To say it is working flawlessly is an understatement. This is in large part due to the fact that we performed maintenance on their existing burner. This control is easy to use and very intuitive.

In the process of some serious plant upgrades, we pulled off the existing EchoStar II, ESII 075 burner. While it was off, we performed some routine maintenance.

We cleaned everything, patched a hole blown in the burner body from the mixing drum “blue smoke” fan, and replaced some missing parts.

Our ESII had lost some natural gas nozzles in the course of its 18-year life and we were getting a bit of aggregate raining through the flame path at the burner end.

This is where the wet material is coming from in the nose of the burner. We cleaned this all up, freed up the spin vanes and replaced the missing nozzles.

To solve the aggregate raining down on the burner, we built a pent-roof over the nose of the burner that extends out about a foot. This keeps the aggregates from spilling through the flame path.

Once we adjusted the NG pressure to 3.5 pounds and started running, I

Routine burner & fuel system maintenance Each burner manufacturer has written a maintenance manual for their specific product. Find that manual and study it. Following their recommendations might well avert a breakdown at an inopportune time. Here are some general recommendations: • Test and verify the operation of all safety systems.

• Examine all fuel and propane lines. Schedule for replacement any that raise a question in your mind. Also look at the propane bottle for the igniter. Check for signs of leakage and damage.

• Check the fuel pump and drive mechanism. Mark any frayed belts, worn couplers or leaking seals. Schedule the fuel filters for replacement, regardless of how long they’ve been in place.

• Check the piping and valving from the supply tank. Now is a good time to verify that shut-offs do, in fact, work. Don’t take them for granted, it may come back to haunt you. Also take a minute and inspect the tank’s filling apparatus. Note any leaks or unsafe practices.

• If your fuel system uses a water separator, consult the manufacturer’s literature on maintenance procedures. In general they should be drained and cleaned.

• If you have a poured ignition port and combustion chamber they should be checked for signs of damage. These units are often easiest to check from inside the dryer/ mixer. These items can fail all at once sometimes following relatively minor damage, it’s best to schedule repairs on any area that raises questions in your mind.

Cliff ’s Notes

performed a burner analysis using my PCA-235 and the CO was around 100 ppm. Perfect. So this burner required no adjustments other than cleaning. Now we have a happy customer, and I'm off to install and tune another burner, this time up in Washington state.

To summarize, the first step in burner tuning is precise control of your equipment. In this case, I made sure all the linkage was secure and not worn, then I set the burner up to factory recommended settings. Next came routine maintenance.

In this case, the burner was already out so it was easy to accomplish the routine maintenance. But taking the burner out is not necessary. All the cleaning and adjustments I made could easily have been accomplished with the burner installed.

Just remember Lock Out-Tag Out procedures to protect yourself and your employees.

As it turned out with this burner, the only real adjustment I had to make was a small one to fuel pressure and it was ready for the upcoming paving season.

Raceway Expansion Comes Full

CIRCLE

Third generation run Wolf Paving reconstructs and repaves Badger Kart Raceway 60 years after their grandfather built the original track

ometimes history repeats itself.

Such is the case when Wolf Paving Company, Oconomowoc, WI, chose to participate in expanding and reconstructing a raceway their grandfather had built 60 years earlier.

“In the early, early days, Lowell Wolf, second generation Wolf Paving owner, and I started racing go karts around a drive way,” says Leeland Wolf.

“We paid an off-duty cop to stop the traffic when the karts came by. We purchased six karts and became a dealer for the state of Wisconsin.”

Soon, the sport was gaining popularity with Leeland holding races regularly, but the county police began to worry about races every night and on weekends so he began looking for a better spot to race.

“Emery Owens, on the west of Dousman, had an onion farm with the high ground just sitting there,” he says. “I purchased the front 40 acres for $100 down and $500 a year until $15,000 was paid.”

Leeland and Lowell Wolf graded a small kidney shape track and paved it with their own original Barber-Greene paver.

“We then had races every weekend.

Participation was 40 to 50 karts a weekend and so I started the North American Karting Association (NAKA),” Leeland says. “We started rules, sizes and some sort of organization and the excitement grew. Each weekend there were more karts and our sales grew as we took on Rupp Karts, UMP Karts and Fox Karts as dealers. We went to dual engines and triple engines.”

The two decided it was time to make the raceway a true road course track.

Lowell and Leeland graded the track, hauled all the gravel in every night and during any spare time. They then hired local contractor Payne and Dolan to pave the track for them.

TRACK EXPANSION PLANNED, RE-PLANNED & PLANNED AGAIN Fast forward 60 years and the Badger Kart Club now operates the raceway, hosting a variety of local, regional and national karting events annually. With racing being held most Sundays, April through October, and free weekly spectator races thrown in there, now was the right time for the track to be upgraded.

The job at Badger Kart Club was to start after the racing season was finished at the end of August/beginning of September 2016.

Tim Hansen, project manager at Wolf Paving and Brian Gallick, the estimator for the job, went to the racetrack, walked the open grass/tree lined area and put stakes in the ground showing the new track layout.

“Brian had a plan in which he scaled the distance from the existing track so

we could use a 300-foot tape measure and get the layout close,” Hansen says.

“Once the layout was complete, the track committee had volunteers come to cut down the brush/trees and remove some stumps in the area.”

Wolf Paving then brought in a Caterpillar D8 Dozer to level off the ground in the new track area and push some of the stumps that were left over into a pile on the edge of the property.

After that was done, Wolf Paving staked the boundary areas again.

Paving a racetrack is much more intensive than other types of paving.

Drivers on these surfaces can go speeds over 50 mph, so even the smallest imperfection can be a safety hazard.

The asphalt mix design was special to help prevent the asphalt from tearing or raveling due to the strong friction and heat generated from the tires on the racing carts — 255 tons of asphalt binder and 255 tons of asphalt surface was used.

The asphalt surface was placed 2-in. thick with an E-3, 9.5mm polymer modified surface. The Wolf team kept seams hot by torching the joints and making shorter pulls while ensuring the seams were also flush with no asphalt elevation variance.

A tack coat was sprayed on the binder asphalt a day before paving so the tack would set up and have less of a chance of tracking on the dump truck tires and on the existing track.

“The track committee came out and walked the site based on our staking,” Hansen says. “They made some changes to the length on a straight away and wanted some other radiuses widened out.”

They brought in an excavator to dig in the new track roadway area and left

52

the dirt/sand material on site for backfill.

Wolf created a firm subbase to support the structure of the asphalt surface. For this project, 12-in. of crushed concrete was used.

“We had to build a temporary stone pad to the site so we could keep the equipment off of the existing track,” Hansen says. “Using the tracking pad, we hauled crushed concrete in and placed it 12 inches thick using a smaller Caterpillar D5 dozer to place the stone and used a large roller to compact.

“Having to build a long tracking pad to get to the track with all of the stone trucks was a challenge,” Hansen continues. “We wanted to limit the access on the existing track so we would have less chance of disturbing or damaging it.”

After the stone was close to grade, once again Wolf met with the track committee who wanted to make additional changes, adding a steeper slope on the turns and changing some elevations in the straight area.

Wolf re-mobilized back in with a small grader, roller and skid loader, and placed the remaining crushed concrete base to the elevations and graded the track close to the final elevations.

“We then met with the track committee again, and they wanted further changes," Hansen says. "They wanted the slope on the turn even steeper and widened out another area in case they decide to race on the track in a different direction."

The track committee reviewed the next step in the process and realized their initial project proposal did not accommodate racing in both directions. To accommodate these additional changes,

To pave the track, Wolf had to drive on the adjoining, existing track with trucks and equipment. They loaded the dump trucks with 15-ton loads so they were lighter on the existing track. They let the asphalt binder sit for a couple of days before paving the asphalt surface.

Wolf Paving created even steeper slopes on the turns and widened the track in specified areas.

With the footprint of the track approved, the last step for the subbase installation was to use a large motorgrader to compete the final grading and compaction.

Rain came, heavy rain, Hansen says, and Wolf had to wait until the area dried out before placing other equipment on the track for final grading. The crew had to replace the damp aggregate with dry and the project proceeded on schedule.

“This took about a week before we arrived back on the track,” Hansen says.

Badger Kart Club Raceway Becomes Wolf Paving Raceway At the end of 2016, Badger Kart Club and Wolf Paving announced a multi-year partnership to rename the historic track Wolf Paving Raceway. Wolf Paving began its tenure as naming rights partner on January 15, 2017, and became the second company to serve as track title sponsor in Badger Kart Club history, following Briggs & Stratton.

The Oconomowoc-based Wolf Paving is a third generation, family-owned paving contractor with locations throughout Southeastern Wisconsin. “We are very excited about partnering with Wolf Paving; both as the title sponsor of the track and on the expansion of our facility,” says Club President Al Weisensel. “We are confident this new partnership will bring a heightened level of excitement for both the racers and spectators at our facility moving forward.”

M Series 140 Grader with slope controls and final graded and compacted the track. Then rain came again. With the dampness and the wet weather, there were some areas in the base where water was sitting next to the track and infiltrated the aggregate so we had to come back with a skidloader and roller and dig out the wet material and place dry material back in."

PAVING TO PERFECTION With a solid foundation approved and in place to support the new racetrack, the paving team began their preparations.

Paving a racetrack is much more intensive than other types of paving. Drivers on these surfaces can go speeds over 50 mph, so even the smallest imperfection can be a safety hazard. Wolf Paving started paving the track by starting in a slower rate of speed area, on a turn, and then proceeded to pave the rest of track.

“We paved the large oval first and then the spurs that came off of the large oval last,” Hansen says. “To pave the track, we had to drive on the adjoining, existing track with trucks and equipment. We loaded the dump trucks with 15-ton loads so they were lighter on the existing track.

We let the asphalt binder sit for a couple of days before paving the asphalt surface.

“We sprayed a tack coat on the binder asphalt a day before paving so the tack would set up and have the least likely chance of tracking on the dump truck tires and on the existing track. The asphalt surface paving was determined to be done in the afternoon on a warmer day of the week for a better finish.”

The asphalt binder was placed 2-in. thick with E-3, 12.5mm asphalt.

“The track committee then met with us and we marked out where the committee was going to pour concrete rumble strips in the shoulder areas of the turn radiuses,” Hansen says. “They wanted us to over pave 6 inches wider in those areas so we could cut the asphalt off for a clean edge for the concrete.

rumble strips.”

The asphalt surface was placed 2-in. thick with an E-3, 9.5mm polymer modified surface. The Wolf team made sure to keep seams hot by torching the joints and making shorter pulls while making sure the seams were also flush with no asphalt elevation variance.

“We did this by paving at a lower rate of speed and paying attention to the finished product,” Hansen says. “We had the asphalt material tested for quality control, and density was taken for proper compaction of the track asphalt. The special oil was determined to be used on the surface

by Mark Sweeting from ATS testing. The asphalt mix design was special to help prevent the asphalt from tearing or raveling due to the strong friction and heat generated from the tires on the racing carts. 255 tons of asphalt binder and 255 tons of asphalt surface was used.”

After the track was surfaced, Wolf string lined the radius areas where the concrete would be poured and used a cart saw to carefully cut the asphalt edge for concrete placement. The concrete team formed up the concrete areas and completed the pour.

Wolf Paving “The main challenge of this job was brought in an taking a flat picture of a track layout excavator to dig and presenting it to real world applicain the new track tion,” Hansen says. “The elevations and roadway area design of the track changed in the field and left the dirt/ based on visual appearance and racing sand material on practicality.

Paving the Way for a New Traffic Design in

North Carolina

S.T. Wooten tackles a project that involves re-paving a busy two-mile stretch Highway 74-76 in Wilmington and executing the state’s second-ever diverging diamond interchange (DDI) raffic management is a difficult part of road construction, but it’s even tougher when it’s peak season near the coast and you’re implementing an innovative new design scheme. These are some of the major conditions we at S.T. Wooten recently faced with a project for the North Carolina Department of Transportation (NCDOT), involving re-paving a busy two-mile stretch of road on Highway 74-76 in Wilmington and executing the state’s second-ever diverging diamond interchange (DDI).

Most states now have at least one DDI, which are said to reduce fatal crashes by more than 60%.

The DDI is a newer design that is growing in popularity across the country due to its ability to help ease traffic and enhance safety around congested interchanges. It may appear a little visually weird at first glance, but the DDI essentially allows two directions of traffic to cross to the opposite side of a roadway for easier access to a freeway. It helps move high volumes of drivers through an intersection more smoothly without needing

T

Is a DDI better in an urban or rural setting?

The DDI can be placed in any setting. A DDI in a rural area may have the advantage of different signal progression options. A DDI in an urban area has the advantage of being able to fit in a tight area. The traffic volumes usually guide the consideration for the DDI no matter what setting it is in.

extra lanes and traffic signals. The design also eliminates left turns against oncoming traffic, reducing the risk of accidents happening between vehicles coming from opposite directions.

The DDI was an ideal fit for the site of the Highway 74-76 project, a unique location near the Brunswick River crossing where the two growing towns of Belleville and Leland converge as drivers head into downtown Wilmington.

Making matters more complicated, this highway provided the only access for vacationers to get to some of the area’s most popular beaches. In fact, we found traffic was pretty much a constant obstacle in this area during the daytime, so we knew it would be a major factor for us to anticipate and plan around in order to meet milestones in each phase of construction.

PUTTING PLANNING INTO PRACTICE As my dad used to say, "No one likes change except for a wet baby." Along the same lines, drivers don’t want to deal with road construction in an already congested area, even if the end result is beneficial.

Keeping public concerns in mind, we worked closely with local officials to ensure all project work was done in conjunction with NCDOT guidelines and caused as little disruption as possible for area drivers. Doing this the right way required keeping at least two lanes of traffic open at all times in and around the job site – not a small task for our crews and one that would require careful execution.

Since traffic was an ongoing challenge during the day, we implemented a strategic plan that maximized night work for priorities like grading and excavating.

This allowed us to take advantage of off-peak hours when less people were on the road to get major work done and keep the project’s momentum pressing forward on schedule. With the often extreme daytime high temperatures we experience during warmer months in the South, this provided the added benefit of giving our crews a bit of cooler working conditions.

For the DDI’s paving and striping, we nailed down two weekends where traffic would be closed off completely from the site. We made sure every minute of those 48-hour windows counted with crews

rotating around the clock, ultimately working to ensure we got the job done right and on time.

Understanding there would be an adjustment period for the public upon the onset of the new DDI, we rolled things out on a Sunday when traffic was its lightest point – providing an opportunity for drivers to transition into the new traffic pattern.

SAFETY STANDARDS Proper planning was key in tackling traffic challenges and ensuring successful execution on this new design, including the steps we took to protect drivers and our crew members during construction.

Because people’s safety was at stake, it was important to have a plan in place to eliminate risk factors and effectively maintain the site.

First and foremost, we knew we would need to use outside resources to help manage traffic effectively.

We implemented a strategy using two traffic officers, one set up on each end of the DDI, to help direct drivers through

There are two unconventional elements that need to be addressed through proper signing and striping.

The first is the crossover movements.

Lane markings should go through the crossovers with thru arrows preferred both before and after the intersection per the 2009 Manual of Uniform Traffic Control Devices (MUTCD). The thru intersection lane control signs should be placed next to the signal heads for added guidance. The second unconventional element is having a shared left lane for thru and left turns. Guidance should be given on the approach to the interchange as to which lane is appropriate for each movement. An additional intersection lane control sign should be placed prior to the left turning movement along with the appropriate arrow markings on the pavement.

The lane control sign must be placed in a proper location so that drivers won’t see it at the crossover.

and around the work zone. In instances where someone was confused or needed help with direction, which did happen on occasion, the officers were there to quickly address the issue and help assist the driver before the situation escalated and became a bigger problem.

To keep our crews safe in the face of potential hazards that come with road work zones, we took time to understand

What should the crossover angle be?

AASHTO states that an intersection should be as close to a 90° angle as possible. However, the reasoning behind this is mainly due to turning movements.

In the DDI, there are no turning movements at the crossover. Therefore the only concern should be to have enough of an angle to avoid wrong way movements that could lead to a head-on collision. The best way to prevent head-on collisions is to not have a direct path from any travel lane from the one approach into the approach in the opposite direction at the crossover. If constraints prevent this from being possible, there should at least be an effort to avoid a direct path on the outside lanes into the opposing traffic.

the traffic patterns during each phase of construction. This helped to ensure the right placement of materials, including concrete barriers and traffic signals to inform the public.

When it comes to maintaining work zone safety, a simple checklist can serve as a great tool for project managers to use in outlining all materials and equipment that are needed and to understand those items that may need to be stored when not in use.

While safety is always a huge priority, the traffic we faced day in and day out on this project made communication all the more important. From the foreman to the crew, it was crucial for us all to be on extra-high alert. It’s true that you can’t predict who or what is going to come in contact with your work zone at any given time, but the commitment our team had to look out for each other and the public went a long way in reducing safety risks.

TAKEAWAYS When all was said and done, we completed the project by the mid-November deadline to the satisfaction of both the NCDOT and driving public. It’s never fun for the public to deal with road construction, so it’s great to see how the finished product benefits people – and this one was special.

It was incredibly rewarding to receive the positive feedback we did after the project was completed, which included the local municipalities and people who lived in the area. It really makes all the hard work worth it.

Paving the DDI was such a unique experience on so many levels, from the design innovation to dealing with unique traffic challenges. Our collective experience, knowledge of the area and careful planning really helped us stay on track, minimizing traffic delays and maintaining safety for all.

It took a group effort across the board: from our design-build and management team to the great execution of our crews and contractors. Having a trusted team that truly works together will continue to be our foundation for producing top-notch results. AC

Asphalt Contractors Inc. Tackles Challenging High School Sports Facility T Wisconsin contractor commits to reconstructing and paving a difficult high school running track project

Approximately 1,800 tons of E mix asphalt was placed in two layers. ACI laid the base course, placed tack and then placed the surface course of the running track.

he construction of a sports track tends to be more challenging than your typical parking lot paving jobs. Asphalt Contractors Inc. (ACI), located in Union Grove, WI, knows this to be all too true after working on the Union Grove High School running track in their hometown.

The initial project was a result of a $3 million dollar referendum to upgrade the athletic facilities. ACI was hired as a subcontractor to provide the stone base and asphalt paving on the running track.

The project began in early spring with the target completion date prior to the first day of school in the fall semester.

In addition to the running track, the football field was to be regraded and synthetic turf installed. ACI was to then pave both ends of the field along with a long jump and pole vault area.

OVERCOMING SUB PROBLEMS The design specifications called for a drainage system that ran around the inside perimeter of the running track.

The existing track was removed and the grade on the football field was changed to accommodate the less than 1% inward drainage specification.

ACI came in and began with proof rolling the subbase provided by the excavating contractor.

“The entire track area failed,” ACI owner Bob Kordus says. “So our first step was to stabilize the surface. We used a Portand stabilization method where we spread Portland cement on the subgrade, added water and pulverized the surface to mix in the cement with the subgrade.

The subbase was then fine graded and compacted.”

ACON0517_58-59_JobsiteRunning_LJ.indd 58

4/27/17 8:53 AM

This process provided a stable surface that passed proof roll and enabled ACI to place the stone base. 3,700 tons of 1-1/4-in. dense graded base was placed in two days. Throughout this process, ACI had to work around and with the subcontractors installing the artificial turf, bleachers and score board.

“We are a local contractor to this area, and I am a school board president at one of the feeder schools to the high school,” Kordus says. “We were also the only local contractor used on the project. Our work progressed on schedule, but I had a sense that the other subs had pressure to perform at other districts and could fall behind, this caused me to check their progress on an almost daily basis.”

It was because of this constant monitoring that on one day Kordus observed the turf contractor and general contractor arguing at mid-field.

Evidently the base was too dry and the turf contractor was telling the general contractor to expect a delay.

“I approached them because their language was not acceptable in the school environment,” Kordus says. “When I found out what the problem was, I simply got some sprinklers and garden hose from our shop and turned on the water.

Fifteen minutes later the turf contractor was turning them off because the base was to wet. Problem solved.”

ADDING MORE WORK Due to the topography and proximity of the running track to the tennis courts and school, the construction of the new track would prohibit any future repairs to the tennis courts.

“The courts were in average to poor condition,” Kordus says. “I approached the school about the problem and was

told there was no money in the budget to repair the courts."

ACI elected to repave all four courts, including cracksealing, petro-mat, net post replacement, paving and color coating as a donation in honor of Kordus’s mother S.M. Kordus.

“My mother is a very avid tennis enthusiast, subscribes to the tennis channel and watches tennis everyday,” Kordus says. “She has been with our company from the beginning and is still active in our business at 95 years young.”

In honor of ACI’s generosity to the school and the project, a memorial plaque was placed in the tennis court area with S.M. Kordus’s name.

PAVING TO PERFECTION With the tennis courts paved, bleachers, electrical and turf installed, ACI was able to begin the paving process on the running track. ACI was extremely conscious of every detail to make sure the highest level of utilization was in store for this space. The track circles the football field and needed to look and function at a professional sports level.

“Obviously the track was to remain an oval – however there was no reason it couldn’t be as wide as possible and have more than four lanes,” Kordus says.

“Running tracks also present a unique challenge because a track is a circle with no specific start or stop area. The work at the start and stop must be provided by hand which leaves no room for error.

We used a Caterpillar AP1055B Paver with Topcon Grade & Slope controls to achieve the desired grade control.”

“Union Grove is our home,” Kordus says. “Our communities children go to this school, our employee’s kids go this school. We had a high level of passion entering into this project and were determined to finish with perfection. Schools are important no matter what village, town or city they are located – these kids are our future and deserve the best resources we can offer.

“Because of my involvement as a school board member and local contractor I wanted this project to be perfect and run smoothly,” Kordus finishes.

“Due to the dedication of our employees, using the proper equipment and using consistent standard construction practices, we delivered a first quality product that I am proud of.” AC

How to Preserve Low-Volume

ROAD

Iowa’s Midwest Coatings Co. relies on slurry surfacing to extend pavement life

A

pavement maintenance contractor in the upper Midwest is helping small municipalities preserve their pavements with value-added pavement surfacings.

Early last fall, Midwest Coatings prepped streets of Farragut, IA — in the southwest corner of the Hawkeye State — for winter with a series of road repairs,

followed by slurry surfacings.

"We had been to Farragut in late summer to repair edges sloughing off into drainage ditches," says Tracy Thompson, president, Midwest Coatings Co, Inc., Modale, IA. "We milled that out and placed hot mix asphalt for repairs and returned to surface the pavements."

With Midwest Coatings, slurry surfacings — thin, dense-graded, cold mixed overlays — begins with crack filling, then sweeping or brooming, followed by covering up of manholes and water valves.

In September 2016, Midwest Coatings surfaced Webster and New Orleans streets in Farragut, a total of 7,000 square yards.

"We are placing a CSS-1h emulsion using a 3/16-minus limestone aggregate," Thompson says. "It's very fine, and limestone is the most readily available aggregate in this area. It leaves a nice, finished surface and it's DOT-approved. When we can, it helps to use the same material on every job, as it keeps us from having to calibrate equipment each time."

Farragut is located in Fremont County, IA, and in 2010 had a population of

ASPHALT CONTRACTOR MAY 2017 www.ForConstructionPros.com/Asphalt

ACON0517_64-67_PresLowVol_JL.indd 64

ADS 485. As such, generating funds for infrastructure work can be difficult. But these street resurfacings were funded in part by a state grant.

"Most municipalities in Iowa receives a state Road Use Tax for pavement work," Thompson says. "Some will skip work one year and combine projects the next. That's what happened here, when our work on New Orleans from 2015 was combined with Webster in 2016."

And the work in Farragut was ideally suited for pavement preservation with "the right treatment on the right road at the right time," as promulgated by FP2

www.ForConstructionPros.com/Asphalt

ACON0517_64-67_PresLowVol_JL.indd 65

Inc. and the National Center for Pavement Preservation. The streets were in relatively good shape, perhaps losing small aggregate from the surface, but eminently serviceable.

"Now is the time to put these treatments on these streets," Thompson said in early autumn.

"Their timing is right. You will see a lot of chip-sealed streets in these towns, but Farragut laid hot mix asphalt, so we have a nice substrate on which to place these slurry surfacings. A lot of times someone will try to slurry an existing chipsealed street. They will be in pretty bad shape sometimes, and they're not ideal candidates."

PREPPING MACHINES In addition to street prep, getting the slurry pavers ready is the first task of the day. Thompson's crews were prepping two VSS Macropavers for the work ahead.

"We went ahead and loaded the trucks with oil in our shop and are loading them with rock and getting the box set up for the right width in the town," Thompson says. "One street is 18 feet wide, the other is 20 feet wide, so we have to adjust our box as it's normally a bit wider."

A test strip will be about 100 feet, to confirm all is set to what it should be.

"We make sure everything is looking right and working the way we like it," he says. "Then we'll continue with the placements."

A minor amount of hand work with squeegees was required and before that, branches were trimmed. "The city had a bunch of trees that were hanging over the streets more than we'd like, so they were kind enough to do tree trimming before we arrived," Thompson says. "These trucks are pretty good-sized, so we need ample space above to get clearance."

In advance of brooming, Midwest typically will seal cracks larger than 1/8inch, but on this project there were none.

"If there are cracks larger than 1/8-inch,

we will rout and seal those," As with other Thompson says. "But those pavement maintenance were nonexistent on this and preservation job, and because the slurry approaches, pavement design we are using will fill must be cleaned before any cracks that are smaller accepting a slurry seal than that, routing and sealso the slurry adheres ing was not necessary." better and lasts longer.

Logistics plays into how Thompson programs his work. Midwest Coatings was placing the slurry surfacings in Farragut in the late morning, and then would move to another job site later that day as the season was coming to an end.

"This morning we traveled about two hours to get to Farragut," he says. "Our next move this afternoon is about six hours away. Our goal is to get this work wrapped up so we can mobilize to our next project."

MIGRATION TO SLURRY SURFACINGS Midwest Coatings is relatively new to slurry surfacings. "We started slurry sealing about four years ago," Thompson says. "The state of Iowa began combining slurry work with other types of work that we already did and we felt that we would be missing out on some business if we didn't do slurry. So we jumped into it, buying two VSS Macropavers in 2013."

At first Thompson considered buying used equipment. "I found myself on top of a slurry paver in the pouring rain in a really bad neighborhood in Miami," Thompson says. "My wife was sitting in a rental car looking at me, thinking 'what are we doing here?' It was then that I realized slurry seal machines are not something you buy used. You go new.

The manufacturers will provide so much help to you as you learn to use them, and VSS has been really good about helping us with every aspect of the machine. We underwent a learning curve the first year, but now we have it down."

Midwest Coatings' agency customers are preferring slurry surfacings to chip seals because they represent a valueadded product that simple, conventional coatings can't provide.

"Chip seals typically can leave loose aggregate," Thompson says. "We've used that to our advantage to promote slurrying instead of chipping. But we also chipseal. So if we have a situation where the customer wants to do a cape seal [a slurry or micro surfacing placed over a fresh chip seal] then we are equipped to do it."

Midwest had the slurry assemblies mounted on Peterbilt 348 chassis, also

Especially for low-volume roads, slurry surfacing is becoming an increasingly popular preservation option.

new at the time. "You can put the assembly on anything you want," Thompson says. "We already had a relationship with a Peterbilt distributor, so with the assistance of VSS, we got them spec'd out exactly the way they should."

Midwest's VSS Macropaver assemblies are equipped with an 850-gallon oil (emulsion) tank on the driver's side, and an 850-gallon water tank on the passenger's side. An aggregate bin is located behind those tanks, and an operator's station is at the rear, with the pug mill situated right there.

Emulsion, water and aggregate are combined at the pug mill before entering the towed box, which places the slurry surfacing. "We also have a fines feeder if we want to introduce portland cement per the mix design, and there's also an additive tank," Thompson says. "In Farragut we are not using cement or additive."

FINE-TUNING MIX The asphalt emulsion already contains water, but additional water is added depending on ambient conditions.

"As the temperature and humidity changes throughout the day, you may need to add a little bit more water," Thompson says. "It also depends on how much moisture is in your aggregate. You may need to adjust the mix as weather conditions change."

Hand work by the Midwest Coatings crew fine-tunes the slurry surface as needed.

www.ForConstructionPros.com/Asphalt

ACON0517_64-67_PresLowVol_JL.indd 67

Nonetheless, the slurry primarily is the asphalt emulsion with aggregate, with water dosed as needed. The CSS-1h emulsion used was not polymer-modified and was breaking within an hour, with no traffic allowed until the break. "We came out days earlier with flyers to notify the residents on the streets on which we were working," he says. "You have to make sure everybody is on the same page."

In addition to slurry surfacings, Midwest has the ability to do micro surfacings with its Macropavers.

"We also do a lot of what Iowa calls 'slurry leveling'," Thompson added.

"If you have transverse cracks that are causing vibrations, we will slurry those transverse cracks. We also will do a strip slurry seal down the centerline or shoulder joint."

Iowa specs on these processes may be seen here: iowadot.gov/erl/current/GS/ content/2319.htm Midwest Coatings provides a full line of pavement preservation treatments, including crack routing and filling, sawing and sealing of PCC pavements, chip seals, slurry sealing and micro surfacing.

machines. In addition to two older Bart Mills, set up for multiple-sized heads, Midwest has a Wirtgen W 600 small cold mill with conveyor, used for patch work.

Midwest Coatings also operates two, 2,000-gallon distributors from E.D. Etnyre & Co. used for chip sealing and fog sealing. One was used in Farragut to supply emulsion as the job was too small for a transport drop. A new Weiler Model 385 intermediate-size paver also is used by Midwest for city street paving and spot overlays on higher volume pavements.

FIVE Safety Awareness Tips for Asphalt Paving Two recent paving-related deaths underscore the need for workers to closely monitor their jobsite surroundings

R

ecent headlines have served as an important reminder for crew safety. On March 28, in Illinois, Jake Eiler, 58, was completing maintenance on an asphalt paver when the machine rolled over him, causing fatal injuries. It's still unclear whether Eiler fell from the paver or was trying to work on it when the accident occurred.

On April 11, Marty Dale Whitmire, 48, of Liberty, SC, died at the scene after a asphalt dump truck struck a power pole and caused the lines to fall and hit his body.

Each year, there are thousands of injuries and triple-digit numbers of fatal accidents related to machine and equipment operation. Here are five tips that you can easily print out and give to your crew. Encourage them to read it daily.

1

TAKE CARE GETTING ON & OFF EQUIPMENT Did you know that getting on and off the machine is the number one cause of injury to equipment operators, forklift drivers and truck drivers? When it comes to a moving piece of equipment like a paver, make sure you're mounting and exiting the machine properly.

First, check your gloves and boots.

Clean the mud off before climbing, and use "high grip" gloves for a secure hand hold. Next, use a three-point stance going and coming. Use large size hand and foot holds. Securely engage the entire hand and foot, avoiding a toe-hold or fingerhold grip. Use a step ladder for access when no hand or foot holds are provided.

Avoid carrying objects while climbing.

72

If the machine needs additional hand holds or steps installed, do it. Operators come in different sizes. Make it as easy and safe as possible to ascend/descend. Avoid the need to stretch by putting the grab rails where they're easy to securely reach.

When exiting the machine, correct practice is to lower yourself in a controlled manner — never jump!

2

DON'T CROWD THE WORK AREA Ask any roller operator what their biggest headache is and they will tell you without hesitation — people on the ground crowding the machine. People love to stand and watch the operator compact the mat, but why create an exposure to injury when none needs to exist?

People on the ground must stay well away from the machine operating area.

Review this important point at safety meetings. Foremen need to enforce this, not the operator.

When ready to start work, use the horn to warn people to stay back; stop the machine if needed; and always check your back before backing up the machine.

3

OVERHEAD/BURIED OBSTRUCTIONS Be aware of overhead obstructions and underground utilities, including electrical lines, water, sewer, gas, telecom, etc.

Definitively mark or warn of overhead lines or low clearances and make sure all dump operators are aware of these before entering the work zone.

Use sawhorses, signs, barrier tapes, etc., to indicate obstructions. Take no chances. The crew in South Carolina sure wishes they didn't.

4

LOADING/UNLOADING EQUIPMENT Even on level ground, there is a risk of machine roll-over during loading or

unloading. Make sure you are centered on the ramps and stay straight. Allow enough room to maneuver the trailer and machine, which is sometimes difficult on tightly compressed jobsites.

Use a spotter for guidance. Make sure the machine clears the ramps before turning. Keep people away from the sides of the machine during loading/ unloading.

Check the trailer deck, clearances and stability. Use proper tie-down procedures. If using compression chain binders, use caution when opening the handle. The load may shift just enough to add tension to the chain and the handle may spring open. Use safety tie wires or switch to ratchet binders.

5

PROPERLY SECURE PAVING AREA Training your crew to be safe is just the beginning. They also need to be kept safe from the traveling public. This is best accomplished by crew members that are visible in a work zone that is well marked with signs and barricades to let drivers know to stay out or slow down.

Contractors should devise temporary traffic control plans (TCPs) for their sites, as well as follow the standards as specified in part six of the Federal Highway Administration's Manual on Uniform Traffic Control Devices (MUTCD).

Ample lighting should also be present in the work zone in addition to mandating that all crew members wear proper reflective safety apparel.

We don’t want your crew to be a headline for an accident. Take time to review safety with them daily. You can never talk about it enough. AC

How

WORKING NIGHTS Can Affect Your Employees

Operator fatigue affects your business – here’s what you can do about it

D

ue to the reduced or impaired alertness caused by fatigue, the inevitable net result is increased human error and reduced ability to work safely and productively. Numerous scientific studies and extensive field experience confirm that workers with higher relative fatigue index are more likely to experience sleepiness, nodding-off and making mistakes while working, as well as nodding-off or fighting sleep while commuting to and from work.

www.ForConstructionPros.com/Asphalt

ACON0517_73-75_SpecialSafety_LJ.indd 73

Fatigue also affects mood. In 2002 the National Sleep Foundation found that people who do not get enough sleep are more likely to get impatient or agitated, and they have difficulty getting along with others. Increased irritability and stress negatively influences personal, work and family relationships, resulting in inadequate/ineffective communications, and correlating with increased absenteeism and turnover as well as reduced morale and poorer labor relations. In fact, industrial surveys reveal that absenteeism rates are nearly double in facilities with severe fatigue problems, as compared to facilities where fatigue is not a problem.

FATIGUE LEVELS The consequences of fatigue also impact a company's operating efficiency and costs. Fatigue results in reduced productivity and customer service quality, reduced operating reliability and decreased operating profit, increased health and wellness costs, and higher overall costs, risks and liabilities. Industrial survey data further indicates that Workers' Compensation costs per employee per year were almost five times higher in facilities with severe fatigue problems, compared to facilities where fatigue was not a problem.

Virtually every industry suggests that

SPECIAL REPORT 80% to 90% of all their accidents and incidents are human-error related.

Equipment, maintenance and human costs pose enormous risks, so safety is indeed a "condition of employment." Yet mental errors, personal injuries and property and casualty damages are not infrequent occurrences.

While some of these incidents can certainly be attributable to inexperience or behavior, the vast majority are more typically physiological in nature. Adjustment to night work, shift rotations and/or overtime create health, safety and performance problems for operators. By every measure, performance decreases at the beginning of early morning shifts, during the post-lunch hours and during overnight shifts … particularly during the predawn hours.

Research has found that the number of fatigue-related accidents is considerably higher at night than during daytime.

In fact, a study found that drivers are 50 times more likely to fall asleep at 2 a.m. than at 10 a.m. No matter how well trained, skilled, motivated, or experienced, operators are frequently compromised by fatigue. Behavior becomes erratic and deviat — not willfully but because of our physiological nature.

As a result, incidents are often misdiagnosed as being due to behavioral problems, when they are actually physiological in nature. Thus, understanding human physiology is key to successfully identifying and managing the inherent problems of working the night shift and fatigue-related human error.

The resultant costs of fatigue are far greater than just those of safety, although the $2 billion already spent on cleaning up the Texas City Refinery mess should be enough justification to proactively address this issue. While there were certainly technical and equipment failures involved in this unfortunate incident,

74

the U.S. Chemical Safety Board in 2007 also cited fatigue due to understaffing and excessive overtime/consecutive shifts as a causal factor.

Fatigue also correlates with higher maintenance costs, lost productivity, increased turnover, absenteeism and presenteeism, higher health and wellness costs, reduced customer service quality, higher operating risks and liabilities, and, ultimately, reduction in overall operating profit.

In his book, The Twenty-Four Hour Society: Understanding Human Limits in a World That Never Stops, Martin Moore-Ede established the following conservative estimate of the global costs of fatigue: “We can certainly argue and debate over the magnitude of this cost estimate, but even if Moore-Ede is only partially right, the cost of fatigue is still enormous. The good news is that it clearly represents recoverable opportunity, and a whole new avenue for improving operator safety and performance that has been largely overlooked for the better part of the last century. Moreover, with today's ability to measure and quantify the costs of fatigue, it is now possible to build a compelling business case and ROI proposition to justify a proactive Fatigue Risk Management System (FRMS).”

Fatigue correlates with higher maintenance costs, lost productivity, increased turnover, absenteeism, higher operating risks and much more.

INSTALLING AN EFFECTIVE FATIGUE RISK MANAGEMENT SYSTEM So how as a company, or as operating managers, can we objectively, systematically and measurably eliminate fatigue from our operations, thereby reducing our costs, risks and liabilities. And is it really possible to increase operational efficiency while at the same time improving employee health, safety and quality of life to create a win-win proposition?

Perhaps this sounds far-fetched, but it's already being done. With the current knowledge and experience base that exists today, dramatic improvements are being achieved in the way people live and work, to the betterment of both the employees and the business.

The first, and most important step, is to recognize the cause and the huge costs of fatigue and make a corporate commitment to eliminate them. Too many companies are losing money and risking the safety of their employees by not recognizing the importance and the urgency of fatigue management.

This is evident by the fact that over 90% of shiftworkers receive no training on how to manage their schedules and shiftwork lifestyles. We see many shiftworkers who are well trained and skilled at their jobs, but who have never been taught how to deal with fatigue, better manage their sleep or adapt to the inherent physical and social challenges of shiftwork.

As a consequence, they develop bad habits and/or become victims of common shiftwork pitfalls that compromise their ability to perform to their fullest capabilities. This is just one of the many reasons that, according to a 2003 study, shiftworking employees conservatively cost companies $8,600 per person per year in excess costs over and above their daytime counterparts.

Once company management has made a corporate commitment to reduce fatigue and optimize the productivity and safety of their workforce, they need to develop a comprehensive, sciencebased, fatigue risk management plan. To be successful this plan must at the very least: • Educate your managers, supervisors and others to achieve consensus and stakeholder support within the company • Provide training for employees to empower them to take more control over reducing their personal levels of fatigue, as well as better coping with night work (especially with new hires) • Reinforce the training and personal commitment to behavioral lifestyle change by providing educational support publications and practical night work information to operators on a regular basis • Educate/train supervisors on how to identify and intervene with tired operators • Re-evaluate work schedules and overtime policies and practices to ensure they are not causing excessive fatigue • Optimize staffing and crewing levels to maintain manageable overtime levels • Evaluate the indoor and outdoor work environment for potential

modifications that could reduce fatigue (e.g. more mentally stimulating control rooms, etc.)

• Evaluate work tasks and activities for opportunities to make them less boring and monotonous • Re-evaluate operating policies and procedures that may no longer be valid, in light of our human physiology, and that may actually be counterproductive • On a regular basis, screen and treat sleep disorders that are prevalent among night workers and provide education on managing sleep • Incorporate fatigue analytics/human error analysis into reporting systems to monitor and track results by collecting and reporting fatigue-related data • Incorporate fitness-for-duty impairment screening programs • Keep abreast of new R&D initiatives to continually advance state-of-the-art • Establish a continuous improvement process that is not merely today's priority, but rather a permanent core operating value of the company CONCLUSION As responsible managers and operators, we strive to keep our equipment welloiled and well-maintained. We ensure that it is operated in full accordance with the manufacturers design specifications, in terms of temperatures, pressures, flow rates etc. To do otherwise would ensure premature failure, costly downtime, high maintenance and lost productivity/ capacity. So it would seem to make sense to keep what we all tout as our "most important asset" — our people — equally well maintained and operated.

Yet, ironically, our people often are being asked to operate outside their “design specs” every day to support our continuous production requirements.

The net result, as you might surmise, has been premature failure (in terms of sickness and injury), costly downtime (in terms of absenteeism and presenteeism), high maintenance (in terms of health and wellness costs) and lost productivity due to human error.

Continuing to neglect our most important asset will perpetuate this cycle of high cost and catastrophic risk. It is time to understand that these costs, risks and liabilities no longer have to be accepted and financed as part of doing business.

With today's knowledge base, technology and available fatigue/shiftwork interventions, they can be converted into a new source of operating profit and reliability that we never knew or believed existed. Moreover, they can be systematically addressed through a collaborative, human involvement process between labor and management to achieve substantial win-win benefits.

As managers and operators, we have to keep our people as equally well maintained as we do our equipment.

DRYER/DRUM SPECIALISTS “Serving the rock and asphalt industries since 1985” WE ARE SECOND TO NONE IN SERVICE AND SATISFACTION ALIGNMENT

Just as your vehicles need proper alignment, so does your dryer.

Nearly all external dryer problems are caused by trunnion and frame misalignment. Long-term mis-alignment causes damage resulting in downtime and costly repairs. Even units that seemingly float properly can in reality be drastically out of alignment.

SIGNS OF MIS-ALIGNMENT

✔ Metal flakes from tires or trunnions ✔ Trunnion mis-location and trunnion bearing failure ✔ Poor wear/contact on tires and trunnions ✔ High drive motor amperage ✔ Excessive vibration ✔ Thrust roller and bearing damage ✔ Tire pad and keeper wear ✔ Lack of proper floatation Evans & Daniels uses precision laser and sighting techniques to restore your unit to proper alignment settings.

RESURFACING

Evans & Daniels uses highly specialized grinding equipment that can fit into the tightest of spaces. We resurface tires, trunnions, thrust rollers and tire thrust faces.

We don’t require cranes, lifting assistance, or steel framework. In most cases, we can grind during regular production conditions.

THE LAST EXIT |

BY JESSICA STOIKES, ASSOCIATE EDITOR

Roads Learn How to Multi-Task Infrastructure of the future will generate power, regulate driver safety, reduce emissions and even generate revenue for DOTs

The new Wattway installation on the Ray, a solar generating paving surface that will help generate power along the roadway.

A

ccording to the Federal Highway Administration (FHWA), there are currently 4.12 million miles of roads in the United States. Based on that data, roads take up less than 1% of the total land area of the U.S. and yet they still get a bad reputation for just sitting there. Well not anymore.

An 18-mile stretch of Interstate 85 in southwestern Georgia, renamed the Ray C. Anderson Memorial Highway, or “The Ray,” is being built as living laboratory helping advance the ideas that a highway can do even more provide us with a means for transportation.

“We’re at a tipping point in transportation,” says Allie Kelly, executive director of The Ray. “In five to 10 years, we won’t remember a time when we invested a dime in infrastructure spending for a road that only did one thing.”

DON’T JUST SIT THERE With Washington discussing ambitious infrastructure plans, now is the time to make investments in our transportation system for the future. And that is what The Ray is hoping to accomplish.

Drivers crossing the border from Alabama will see solar panels above a rest stop, part of a sustainable electric vehicle charging station along the roadway.

Drivers will also see solar paving material underfoot. Wattway solar panels are thin, heavy-duty, skid resistant

82

PV pavers that can be applied directly over existing pavement, eliminating the need to remodel or build new road infrastructures.

The Ray, Georgia DOT and international technology partner COLAS, unveiled the first traffic-bearing solar road in the U.S. with the installation of a 50-square-meter section, the first of its kind outside of France. The clean energy generated by Wattway at this site will help to power the Georgia visitor center as a demonstration project for a technology that has potential to help reshape the future of transportation.

In the next few years, the addition of more solar panels, sustainable landscaping and Internet of Things technology will make this a smart, sustainable — and most important to its backers, revenue-generating — road to a greener future.

As far as Kelly is concerned, the future vision for roadways should focus on achieving zero deaths, zero carbon and zero waste. On just this 18-mile stretch of road, more than 5 million tons of CO2 is emitted every year. Kelly hopes The Ray can serve as the laboratory where new ideas and revenue models are tried, tested and proven possible.

HONORING THE PAST The Ray’s origins come from a simple observation that a memorial roadway should make its namesake proud. In the case of a highway named after the late Ray Anderson, a pioneering green industrialist from Georgia, that meant it had to be both smart and sustainable.

“We put the name of one of the century’s greenest industrialists on a dirty highway,” says Harriet Anderson Langford, his daughter and president of The Ray, which is funded in large part by the Ray C. Anderson Foundation. “It made

us ask ourselves, ‘how can we transform the transportation system?’”

Initially, the vision for The Ray was to add a solar installation in the median, along with a wildflower garden, to remind drivers about the environmental costs of the transportation system. Since then, The Ray and the Georgia DOT have slowly rolled out a number of new initiatives to improve both safety and sustainability. In 2015, a new electric charging station powered in part by photovoltaic panels, a joint project with funding from Kia Motors, became the first in the state.

This past year, The Ray installed a WheelWright tire pressure sensor at a rest stop right next to the Alabama state line.

The new device helps drivers quickly test and maintain proper tire pressure, a leading cause of crashes.

Over the next year, the foundation plans to add more new tests that will help build out a more holistic roadway.

A one megawatt solar installation will be installed in a right-of-way as part of a joint effort with Georgia Power to turn the highway into a place for power generation and a series of bioswales —landscaped drainage ditches that naturally filter pollution — will turn the areas adjacent to the highway into more clean, sustainable and natural landscapes.

“We have to prove there are benefits here to the investor,” Kelly says. “Our role is to catalyze change, so to do that, you need to focus on everything. We don’t have to just talk about low or zero emissions, we can talk about revenue.

Why miss an opportunity to leverage more for your investment dollar?” AC
