This issue of The AsphaltPro Magazine is dedicated to two things: technology and CONEXPOCON/AGG 2011. I’ve noticed that, similar to the turn of a new century, winding up to CONEXPO sends the construction industry into a sort of burst of technological advancement. There’s more on that concept in this issue’s technology roundup article “Automate Your Production Control” on page 18, so I’d like to concentrate on the “event” side of things here. With technology and automation comes the promise of doing things more efficiently, more quickly, with better quality, with better control, with precision and with confidence. Whether it’s mixing asphalt at the plant, loading it safely from the silo, tracking it by the minute from Point A to Point Z, or placing it at the perfect depth and rolling it to the perfect density, there’s an app for that. What I wonder is will there be a need for that? What are we going to do after the excitement of CONEXPO dies down and we all stare at the messes in our research & development departments. Technology has been on everyone’s collective mind as we rush toward the deadline of March 22—and much earlier if you’re shipping the final product out to a stand in Vegas. Drayage invoices and credit card statements make for a financial hangover that puts corporate bosses in a foul mood. They don’t feel so technologically motivated after CONEXPO, do they? Who carries the load then? Who’s going to come up with the next great idea that provides a super funding idea for the transportation construction industry? Ah, yes. After CONEXPO, we still have to fight for our right to support the nation. The President’s State of the Union address Jan. 25 suggested he’s all for taking care of our crumbling infrastructure. He’s all about getting people back to work fixing our roads, bridges and transportation network. The problem is he’s got this grand idea that we can do all that and build a bunch of high-speed trains that few people are interested in while Congress is going behind our backs with secret ballots to appropriate federal highway funds for whatever special need they come up with. AEM’s Dennis Slater and AASHTO’s John Horsley can get up the morning after such a speech and say they’ll hold the President accountable for his promises (and they did), but who in this country believes that man can get anything besides stump speeches done in the next two years? It’s Congress we have to appeal to. It’s Congress we have to write to. It’s Congress that has to create a reliable highway bill this spring. It’s Congress that has to pass a strong, fully funded highway bill that contains provisions that keep special interest groups—such as Congress—from undercutting the Highway Trust Fund on a whim. It’s Congress that we have to get in touch with and get in touch with right now. You all saw the timeline Jay Hansen outlined in this magazine in December. Get on the ball! The President releases his budget in early February, about the time this magazine hits the streets. By the time dandelions start blooming in the cracks in your concrete sidewalks, Congress needs to have a transportation authorization bill drafted. That’s not a lot of time for members of this job-creating force of ours to get ideas in front of the drafters. Have you informed your representatives of just how important it is to improve roads and highways? As sad as it sounds, you also have to inform them of how important it is to guarantee funding for improving those roads and highways so your state can make long-term, realistic, efficient plans. Stop-gap measures don’t cut it anymore. This is where we put technology and intelligence to work. I asked you what we do after CONEXPO. We can’t wait until after CONEXPO. You and I have to pick up the phone today. After CONEXPO, what does all our fancy technology matter? Stay Safe,

Sandy Lender

NAPA staff met late in December with allied organizations to review an EPA pre-proposal to reduce exposure to particulate matter/fugitive dust by up to 50 percent. Research shows the majority of fugitive dust from asphalt plants and quarrying operations comes from unpaved roads and stockpiles and that aggregate crushing operations produce very low emissions. Because quarries already use best available control technology, the only apparent solution to reduce dust further would be to cut production. NSSGA estimates the magnitude of impact could be to reduce quarrying operations by as much as 67 percent. NAPA members are also starting to encounter more stringent fugitive dust requirements during permit applications and renewals. EPA’s proposed rule is due out in February. NAPA plans to participate in a Fugitive Dust / Coarse Particulate Matter Coalition and will keep NAPA members informed as the issue progresses. Source: NAPA

mix it up Using Test Track Data to Validate Mechanistic Pavement Design Models by Courtney Jones


sphalt pavement thickness has historically been designed based on vehicle type, standardized axle loads and material properties based on results from the American Association of State Highway Transportation Officials (AASHTO) Road Test in the late 1950s. In recent years, however, pavement design has begun to shift toward a mechanistic-empirical framework that uses engineering principles to design pavement structures that will resist specific distresses, including fatigue cracking and rutting, over the required performance period. Mechanistic-empirical (M-E) design incorporates material properties and environmental data, and uses mechanical analysis to more accurately model a pavement structure. Pavement response, which is calculated based on expected traffic loading, can then be used to predict pavement performance through empirical correlations. Figure 1

M-E design is slated to become the new AASHTO standard, with DarWIN M-E software scheduled for release in early 2011. As M-E design is implemented, there is an ongoing need for local calibration/validation of the empirically derived pavement performance models, which depend on both materials and climate. Data from structural sections at the National Center for Asphalt Technology (NCAT) test track provide a perfect opportunity to compare actual pavement performance with that predicted by M-E design models.

Comparing Actual and Predicted Performance A variety of inputs are needed in the Mechanistic-Empirical Pavement Design Guide (MEPDG) analysis procedure, including the following: Figure 2

• detailed traffic data, referred to as load spectra • detailed climate data, such as air temperature, rainfall, wind speed, relative humidity and percent cloud cover • mechanistic material properties—dynamic modulus (E*) for hot mix asphalt (HMA) and resilient modulus (Mr) for granular base and subgrade materials • HMA properties, such as asphalt content, lift thickness and density These inputs are readily available for the structural sections of the completed 2003 and 2006 research cycles at the test track. These sections were instrumented with strain gauges to measure pavement response under loading and were subjected to 10 million equivalent single-axle loads (ESALs) during each two-year testing cycle. Design variables included total hot-mix asphalt (HMA) thickness, HMA mix type, base material type and subgrade material type. All structural sections were assessed on a weekly basis for surface performance (rut depth, fatigue cracking and international roughness index, or IRI) as well as structural response (strain and pressure). A comparison of measured and predicted IRI values for all sections (Figure 1) shows that the MEPDG model gives fairly reasonable results. Several sections, most notably N1 2003 and N2 2003, exhibited severe fatigue cracking—well beyond what is typically considered failure—and the resulting roughness is reflected in the measured IRI data but not in the MEPDG-predicted values for those sections, since the MEPDG model is not based on such severe distress. When comparing actual and predicted rut depths for all sections (Figure 2), it can be seen that the MEPDG rutting model overpredicts permanent deformation, but this can be calibrated or corrected with a simple offset. However, a comparison of measured and predicted fatigue cracking for all sections (Figure 3) reveals mixed results. In several cases, the MEPDG fatigue model does not match actual performance. NCAT plans to continue MEPDG validation/calibration efforts as data becomes available for structural sections currently under loading at the test track.

Test Track Data Used in TexME Calibration

Recent research conducted by the Texas Transportation Institute (TTI) also employed data from previous test track structural sections in calibrating and validating distress prediction models within the proposed TexME design system. To predict rutting, TTI selected the VESYS layer rutting model, which accounts for the permanent deformation properties of each layer. Material properties were determined using dynamic modulus and repeated load testing. Calibration of the proposed rutting prediction model involved three correction factors—pavement temperature, modulus and HMA thickness—that were determined using field rutting data. Eight structural sections from the 2006 NCAT test track cycle, representing a range of rut depths from low to very high, were used to determine the pavement temperature and modulus correction factors. In addition, the LTPP SPS-5 sections on US175 in Texas were used to determine the thickness correction factor. The correction factors were established by minimizing the difference between predicted and measured rutting. The accuracy of the calibrated rutting model was verified using data from three sections of the 2000 test track cycle, with predicted rutting generally matching the rutting observed in the field. The proposed TexME fatigue cracking model, which considers crack initiation and crack propagation, uses an enhanced two-step Overlay Test to determine HMA fracture properties. Preliminary calibration included data from seven 2006 test track sections, some with no fatigue cracking and others exhibiting severe fatigue damage. The differences between measured and predicted fatigue cracking were minimized in order to develop the necessary calibration factors. Figure 4 illustrates the measured and predicted fatigue cracking for section N7. Data from two sections of the 2003 test track cycle were used to validate the fatigue cracking model. Performance data from the current test track cycle will allow further validation/calibration of the TexME distress prediction models.

Process Controls for Asphalt Plants Emulsion Plants • 250.862.8813

producer profile

From left to right, the B&S Light Digi-Loader, Hauck burner control and EZ-Blend controls are within arm’s reach for Plant Operator Benjie Hughes. He can see the extended truck scales and two silos from the control house. The trucks he loads are a mix of company-owned and customers’ trucks. He explained that Nampa Asphalt and Paving Co. runs about 20 trucks of their own. “If we ‘rent’ trucks, they are typically used for hauling gravel and not asphalt as we like to use our experienced drivers for the asphalt laydown.”

Nampa Paving Regains Control by AsphaltPro Staff


ot every company starts out with a plant already in place. The owners at Nampa Paving and Asphalt Co., Nampa, Idaho, had that kind of plan in mind. Back in 1984, they bought an existing company that owned a hot mix asphalt (HMA) plant and put it to work in combination with a grading crew, paving crew and all the trimmings. They had some shuffling to do in the early years. First, they moved their plant to Boise for production around 1990 or ’91. When they moved their headquarters operation to their current location, Karcher Road in Nampa, they purchased an early ’80s CMI PTD300 triple drum rated for 300 tons per hour (TPH) for home base. By 1998, managers decided two plants was one too many for their needs. The company retained the CMI plant and upgraded it with a new drum and baghouse, extended the truck scales and added another silo. In the early 2000s, they 12 february 2011

The EZ-Blend™ system from B&S Light Industries, Oklahoma City, offers Nampa repeatable quality. It can control 2 liquid asphalts, 2 recycled materials, 12 cold feed bins, multiple mineral fillers, baghouse fines, anti-strip, lime, rejuvenator and other materials, thus expanding as Nampa grows. It will handle an infinite number of raw materials and an infinite number of mix formulas with history breakdowns for each.

upgraded the control house with B&S Light controls. They didn’t count on a set-back last winter to force more upgrades. Plant Operator Benjie Hughes told the story of winter 2009/2010 when the set-back occurred. Luckily, Nampa Paving and Asphalt Co. goes from 50 employees in the busy season to a skeleton crew during the down season, and the plant had already shut down when an electrical short caused a problem in the control house. “There was an electrical short in the main panel coming from the power company, which in turn completely engulfed the control house with electrical insulation smoke,” Hughes explained. “With the help of the insurance company, it was decided that everything needed to be replaced, including all the switch gear as it couldn’t be trusted anymore.” The good news is no one was hurt; Hughes attributes that to the season. “No one was hurt because we were down for the winter already.” The silver lining from this dark cloud is Nampa was able to work with Scott Roy of Field Services of Longmont to get a new-to-them control house with new controls from B&S Light Industries. Hughes explained that their previous general manager investigated several companies who provided controls and selected B&S as their best fit. Now Hughes can list the EZ-Blend™, Digi-Loader, Hauck burner control, touch screen controls, and virgin and RAP scale integrators as automation he uses in the larger-and-improved control house. While the house that Roy built from scratch may have been for another client who outgrew it, it met Nampa’s needs perfectly, according to Nampa staff. They say Roy was able to tie it all into the plant perfectly and they attribute the plant’s efficiency to the increased number of automated systems, among a knowledgeable crew. For all this new technology and automation, Hughes had no trouble getting up to speed. “I find it to be user-friendly with an excellent technical support team.” He explained that automation makes the plant operator’s job easier. “The control technology makes all components run consistently when calibrated on a regular basis.” As an example, he used the 2010 paving season. “All mix made in 2010 after the installation of the new control house and controls met all required volumetrics as well as volumetric bonuses on some jobs.” The mixes Hughes boasts about aren’t run-of-the-mill mixes, either. The company now has two silos at 100 tons capacity each and runs recycled asphalt pavement (RAP) about 95 percent of the time, typically at a 15 percent ratio. They haven’t jumped on the warm-mix asphalt (WMA) train yet, but Hughes said management has discussed it. They supply their own crews, of course, but customer needs take up about 10 percent of their production.

Hughes has been with Nampa for 17 years. He started out working on a grade crew and moved up to grade crew foreman. From there, he took over running the plant when the previous plant operator retired. He suggests that other plant operators can adjust to automation and controls as easily as he did because “change is not always bad.” For a company like Nampa, change can range from jobs to responsibilities. The company is known in the Treasure Valley for efficient, quality work. Hughes was proud to weigh in on the crew’s success: “Our paving crew is known in the valley for being the most efficient as they can lay more asphalt in one day than any other according to our plant size. With our 300 tph plant, we can lay over 2,000 tons in an 8- to 10-hour shift. It

would be more with a bigger plant.” In fact, the team at Nampa sees the crew laying closer to 3,000 tons on straight pulls already. One way the crew stays efficient is with veteran workers; another is through good training. “Our paving superintendent has been with us for 22 years and our paving foreman has been with us 16 years, so with seasonal workers and such, it’s not hard to bring them in and train them.” As in Hughes’ case, workers can move up through the ranks when they show promise and skill. It’s that kind of change, and acceptance of change, that makes a good employee in any company. Nampa also keeps its fulltime employees working. “We keep all our key employees busy all winter working on various shop projects. Both our superintendent and foreman have vast knowledge of maintenance, mechanics, fabricating, etcetera, and make sure all the paving equipment is in good order, as well as helping on the maintenance of the hot plant.” While no one can predict the future, management at Nampa Paving and Asphalt Co. has set the company up for success. Hughes stated that the company was able to take on quite a few projects funded with stimulus money in 2010, but the industry can’t expect to dip from that well again. “We’re not sure what will happen in 2011,” Hughes said. “However, we are prepared for whatever comes our way that is a ‘fit’ for us. We are well established with low overhead.” Hughes describes a company that’s free of debt with little or no equipment financing and that has automated production controls to produce bonus-worthy, repeatable mix designs for its dependable paving crew. Nampa Paving and Asphalt Co. is set up with a winning combination for its business, and with a quality plan for its customers and clients, no matter what the next season brings.

project management Manage 2011’s PM Trends for Success ESI International shares top 10 project management success factors for leadership in the New Year by J. LeRoy Ward


n early January, ESI International, Arlington, Va., an international project management learning company, revealed our Top 10 Global Project Management Trends for 2011. Key themes include building the project manager’s (PM) influence, accelerating new leadership and communication skills, and increased use of informal learning approaches such as social media and experiential training. A global panel of consultants and senior executives assembled by ESI identified the trends. 1. Leadership skills will be the PM’s critical success factor. Leadership skills, such as critical thinking, crucial communication and organizational change management, will be strategically imperative project management competencies to master. In 2011’s project management landscape—which will feature more complex projects and greater use of virtual teams—being on time and on budget will require not just a laser-like focus on the triple constraints, but on the requisite leadership skills necessary for an individual PM’s success. The challenge for organizations will be to define what “leadership” means in the project and program management context. 2. No industry will be spared from the war for PM talent. Savvy talent management and retention strategies will be essential to ward off poaching in 2011. Although economic recovery has been uneven worldwide, PMs with the greatest mobility and experience will have the best opportunities for career growth through “overseas” assignments. In particular, India and China will continue to be plagued by a lack of competent and experienced PMs to manage large and complex infrastructure and IT projects. Additionally, as mega-projects at the King Abdullah Economic City north of Jeddah and King Abdullah Financial District on the outskirts of Riyadh kick into high gear, 16 february 2011

more opportunities for work in the Middle East will become a reality. 3. Agile will be seen for what it is…and isn’t. Project management organizations embracing Agile software and product development approaches will continue to grow while being faced with the challenge of demonstrating return-on-investment through Agile adoption. In addition, they will need to disabuse their stakeholders and executives of the expectations set by IT consultants, the media and the vendor community that Agile is the next “silver bullet.” Organizations that do it right— including selecting the right projects for Agile—will reap the rewards. 4. Competency models will be core to managing professional development and promotions for PMs.

As project management gains greater acceptance as a discipline, the hiring, assignment, promotion and professional development of PMs will be based on comprehensive competency models. For these models to be effective, they must be company-specific. Competency models illuminate the behaviors required for a PM to be successful and take on larger and more complex projects. Accordingly, the CLO (or senior HR executive), business unit heads and the enterprise project management office (EPMO) need to work shoulder-to-shoulder to identify and codify organization-specific competencies, thereby building a framework for talent management success. 5. Experiential learning will be more the norm than the exception. The professional development of PMs will increasingly focus on reality-based learning

This Powerpoint slide shows a real process from envisioning a product or trend to releasing it successfully to the marketplace.

Organizations will continue to develop and exploit informal learning approaches such as communities of practice (CoP), various forms of social media, as well as coaching and mentoring. and on-the-job training, an approach certain organizations in Asia have taken for many years. Learning providers will be required to send PMs back to the job from such sessions with the ability to immediately apply what they learned to their current projects. Even the many universities that offer project management degrees will face the challenge of making their courses and programs relevant and practical based on participants’ real projects. The lecture mode is dead. 6. Informal learning for PMs will gain momentum. Organizations will continue to develop and exploit informal learning approaches such as communities of practice (CoP), various forms of social media, as well as coaching and mentoring. With millenials joining the workforce in greater numbers, we will witness more effective use of social learning technologies and approaches, such as wikis, blogs, videos, podcasts and other methods of communication. With four generations now in the workplace, it is not only the millenials who will benefit by such relatively new forms of learning. 7. Project sponsorship will become an area of focus in South Asia. The roles and responsibilities of the project sponsor will be a key focus in South Asia, especially in India and Bangladesh, as organizations try to accelerate their structured approach to project management. Such organizations are trying to avoid the experience of others in their industries around the world whose “spotty” record of success in project sponsorship has contributed in whole, or in part, to less than successful projects. 8. Outsourcing will remain a risky business. The continued growth of outsourcing will force organizations to pay more heed to its associated risks and conduct better due diligence. As a response, organizations will strengthen their risk management cultures and recognize the value of best practices in

contract management. More than a euphemism, the word “sourcing” will replace the term outsourcing as it more accurately describes the resource allocation approach. 9. PMs will team with “change partners” and use structured methods to facilitate adoption. Projects initiate change and PMs are change agents. Yet, they have been illequipped to facilitate the type of change required to adopt the product or service the project delivers. In 2011, we will see more organizations developing and assigning “change partners,” also known as change management experts, to projects to assist in such adoption. Moreover, project teams will slowly, but steadily, increase their use of change management methods, which will be packaged as methodologies. 10. The PMP® will continue its world domination, but will no longer be enough. With 400,000+ holders, the PMP® will continue to be a popular project management credential, outpacing its rivals as the “credential of choice” among practitioners. While most organizations will continue to support their PMs in earning the credential, the value of proven experience and demonstrated competency will take on even more relevance beyond having the certification itself. Project management continues to play a critical role in driving operational efficiencies. Savvy business leaders are putting more stead in project management to fine tune their competitive advantage. Alongside technical savvy, other skills such as negotiation, communication, critical thinking, change management and leadership are taking on new importance for project managers. Influence and organizational agility will be key factors for performance improvement going forward. J.

Automate Your Production Control

by Sandy Lender


istorians tell us that innovations in technology occur more rapidly as society closes in on a new century. For the asphalt industry, automation, software and controls seem to continue evolving even after we passed the 2000 mark. While control house systems and improved paving technology have been a standard for decades, original equipment manufacturers have taken a lesson from computer software support staffs when it comes to providing updates and modifications. For instance, Libra Systems, Harleysville, Pa., provides automatic updates to its plant and fleet controls throughout the year. Customers merely download the update and incorporate a new bit of information instead of bringing a completely new product with a large learning curve for operators on board every year or so. Other OEMs offer similar programs. What it comes down to is providing up-to-the-minute technology for up-to-the-minute automation. “Whether you’re the operations manager, the paving foreman, purchasing manager or accountant, single-point access of all plant controls can provide up-to-the-minute data to maximize operations, maintain accurate inventory and minimize waste,” Astec Industries, Inc., Chattanooga, officials reported. The learning curve mentioned above is something owners don’t have to struggle with any longer. If what you need is plant or fleet management controls, the systems are so varied that there’s bound to be one your plant operator is comfortable with from the get-go. If what you need is paving or compaction automation, everyone from OEMs to on-site paving consultants can help you train veterans to newbies on working the systems with expert skill. “In the past decade, highly configurable software has allowed producers to tailor the systems for their exacting requirements without programmer involvement,” Libra’s Ken Cardy explained. “This includes the ability to add data fields, lay out printing on delivery tickets, add or modify reports, add special logic, create pricing schemes, etcetera. …the configurable and modular design of today’s software allows users to receive new releases and features. “Until recently, operators were asked to put in more and more data, when what they really needed to concentrate on was 18 february 2011

keeping the plants running and making good asphalt. New developments on centralized management software have changed all that by giving the people responsible for the accuracy and timeliness of the data the ability to control it. The great benefit to operators is that they now merely pick the data from lists rather than keying it in. The learning curve for operators is very fast because they have less data to maintain and the software is much more intuitive. Inherently, accurate, up-tothe-minute data is available throughout the company, and the time-consuming task of correcting mistakes prior to invoicing is virtually eliminated.” Even if an operator needs a few hours to learn a system, the benefits are hundredfold. “Automation systems have come a long way in the last 20 years,” Curtis Kieres said. He’s the regional manager for Minds, Inc., Boisbriand, Quebec. “From completely manual operation to remote relay interfaces through PLC logic programs and now fully integrated control environments, the evolution has taken away from the plant operators the tedious and unproductive tasks of running around the plant to gather information and operate equipment, and replaced them with meaningful information, remote equipment control

and automated logic. All this toward the goal of improved productivity, repeatability and better quality control. The operator’s work load is generally reduced, allowing them to be more alert to any mechanical issues, process supervision and contract scheduling.” As Kieres pointed out, having intuitive operator-oriented interfaces makes for a fast learning curve. And that builds the operator’s confidence. Interfacing is something sources mentioned frequently. Gregg Gilpin, director of electronic control systems for Stansteel® Asphalt Plant Products, Louisville, Ky., brought it up in light of system compatibility. “A major consideration to make when researching new asphalt controls for your operation is the system’s ability to interface with the plant’s existing components. … With some controls on the market being inflexible, the customer must be aware of the system demanding only a certain type of input from the mechanical device, thus increasing the cost of conversions by many tens of thousands of dollars. In some extreme cases, the control system will require that an entire motor control center be changed, including the starting devices, which can be cumbersome and cost-prohibitive.”

Check the wiring leading to the control as well, Gilpin suggested. If the wiring is in bad shape, that will be another expense to factor into the upgrade.

The Trimble PCS400 screen lets operators see and control both sides of the screed.

Not all companies make their own controls, but build their components to interface with other OEM’s controls. Tarmac, Kansas City, Mo., offers B&S Light blending and loading controls out of Claremore, Okla. Tarmac builds the control house, start/stop operators, start package and does the field wire in the house. “There is an enclosure with input and output modules that connects the actual plant equipment to the computer inside the control house,” Ron Heap said.

“These units are found in new plants and in retrofit installations all over the United States and Central and South America.” For plant controls, the caveats Gilpin offered give producers a good blueprint for entering a mix-and-match situation carefully. Overall, most OEMs can trade out their controls with other equipment when it’s done professionally, with care and attention to plant requirements, amp pull, the system’s true competence, etcetera. For

paving and compaction controls, equipment exchange is not so easy. As Jeroen Snoeck, paving segment manager for Trimble, Sunnyvale, Calif., pointed out, many systems for compaction automation that are owned by the OEM are provided for one machine brand or certain models only. The Cat AccuGrade Compaction Control System is designed for use only on Cat compactors. It integrates fully with the technology of the machines, allowing the

machines to share information with other AccuGrade-equipped machines. Through the use of AccuGrade Office Suite, it offers another component to paving: managers can access the data to uncover “greater jobsite efficiency” and manage the fleet. The same is true of the Cat Grade and Slope System that is factory-installed and calibrated on Cat asphalt pavers. One compaction system available for aftermarket “movement” is the Trimble CCS900. Snoeck said it’s used as a coverage mapping and pass-count control system for asphalt compactors. “The one outstanding feature is that it is an aftermarket solution that can be mounted on any brand or model of compactor.” That aftermarket flexibility is true of Trimble’s PCS400 paving control system as well. Snoeck described its large 2-dimensional paving display as being easy to learn and operate with both text and icons. The split screen option of the display allows operators to monitor and control both sides of the screed from one display, no matter what brand of screed they’re on. The variety of controls and technology available to contractors and producers is astounding. Whether an owner wants to

find one brand to remain loyal to or wants to mix and match, the options are endless and the training opportunities abound. Once an operator gets past the ever-shrinking learning curves with controls, the technology is designed to make the design of mixes and placement of mixes a more exact science. Luckily for the asphalt industry,

the beginning of the new century has seen continuing advances and innovations from the OEMs who have shared their experiences here, and from many others around the globe. As time goes on, more controls will take more worry out of the asphalt mix equation and put ever more confidence in our product.


Get Optimum Exit Gas Temperatures with Flighting

o get optimum gas temperatures to exit the drum and enter the baghouse safely, the plant operator wants to take a look at what’s happening inside the drum. The operator wants to see a continuous veil or curtain of material as the drum turns. As Bill Garrett of Meeker Equipment Co., Inc., Belleville, Pa., explained it, the producer wants “a fog of material across the dryer so that no heated air can leave the drum without first coming in contact with material.” A proper veil of material starts with well-worn flights churning material in a cascade of falling aggregate for perfect heat distribution. Because energy will take the path of least resistance, heat will travel through any gaps that worn, broken or missing flights allow in the veil. Errant heat means higher exit gas temperatures leave the drum. Brian Handshoe, vice president of operations for Kenco Engineering, Inc., Roseville, Calif., reminded producers of failures—such as worn flights—that influence the veil: “Flights that are badly worn, broken or bent over from heat distortion will lose their ability to veil properly. Problems can also occur when a plant’s burner or fuel is changed drastically and the flights aren’t redesigned to match the change in flame shape.” Handshoe recommends maintaining the original shape and profile of the flighting throughout the life of the flights to maintain an efficient veil of material in the drum. Flights, Mike Mauzy of Reliable Asphalt Products, Shelbyville, Ky., pointed out, serve a sacrificial purpose. They’re obviously less expensive to replace than a drum shell, thus they take the brunt of material abuse.

22 february 2011

by Sandy Lender

“The idea is to have material fall on and scour the flights of the drum and not as much on the shell, saving abrasion on the shell,” Mauzy said. “Not only do they facilitate material veiling, they also serve to prolong the life of the more costly drum shell. That is another reason that they need to be checked and replaced often. They are a normal maintenance item that will save the contractor on fuel cost as well as a much more costly and time-consuming drum shell replacement.” If a producer lets the flights wear and the veil get sloppy, cost overruns will result. Dennis Hunt of Gencor Industries, Inc., Orlando, brought up increased fuel consumption. Meeker’s Garrett added “lower production” to the list of problems. As Handshoe explained, holes in the veil mean hot gases are going straight to the baghouse instead of drying the rock, thus raising exhaust gas temperatures. The aggregate in the veil essentially grabs, absorbs and uses the heat from the burner flame, thus reducing the temperature of the gases exiting the drum. Hunt reminded readers that “It’s the hot exhaust gases that dry and heat the aggregate. To be efficient a ‘veil’ of aggregate must go from the rising side of the drum to the falling side. We want the maximum amount of heat energy transferred to the aggregate. The best measure of this is the side to side temperature of the exit gas temperature at the breeching duct work. The side to side temperature should not be greater than 50 to 70 degrees.” An operator can tell something’s wrong without climbing into the drum to check out the flights or standing next to duct work to measure

temperatures, although equipment inspection is part of proper routine maintenance. Look to the baghouse. “Exhaust gas temperatures higher than those needed to prevent condensation in the baghouse represent heat that is being wasted,” Handshoe said. “Fuel is being wasted to create that excess heat. Reducing exhaust gas temperature is directly related to fuel costs.” By replacing or repairing worn flights, you retain more heat in the drum. That means better efficiency, no matter what type of production system you’re working with. Mike Mauzy of Reliable Asphalt Products, Shelbyville, Ky., explained why flighting is critical to an efficient veil, thus efficient exit gas temperatures, in the parallel-flow environment. “Ideally, you will achieve lower exit gas temperatures by upgrading or replacing worn out flights in a parallel flow drum mixer,” Mauzy said. “In most cases, exit gas temperatures exceed exit material temperatures in a parallel flow drum mix plant. The reason for this varies but in most cases, it can be directly attributed to the fact that most difficult drying taking place in the drum mixer—removal of internal moisture—is occurring when the material is nearly exiting the drum.” He reminded readers that in a counter flow application, the exact opposite occurs, resulting in lower exit gas temperatures than exit material temperatures. “The goal of improving flights is usually to achieve better fuel savings,” Mauzy said. “This is directly tied to lower exhaust gas temperatures, assuming that the exit material temperatures remain constant. Introduction of RAP in a parallel flow drum mixer also negatively affects exit gas temperatures but is offset by the material savings from the RAP.” Obviously, different flights serve different purposes. Depending on which type of dryer and burner a producer uses, she will want to investigate specific flights for the materials and mixes she’ll be running. Mauzy explained: “This is specific to the material, mix designs, RAP percentages, dust percentages, drum design (counter flow, parallel flow), burner type (naturally aspirated, combustion cone, total air), material, moisture, etc. Most manufacturers use a few specific flight types (saw tooth, basket, “J” style, combustion, “L” style, mixing flights) and disperse them throughout the drum in an effort to facilitate optimum material veil. Other retrofit companies attempt to improve upon the OEM flight design by studying even closer the above mentioned specifics of each plant. I recommend that improvement suggestions need to be catered to the specific plant and situation.” Handshoe concurred that getting the right flight for the right application points to success. “Each manufacturer of plants and burners has done extensive research to design a flight, and therefore a veil shape, that works best in their plant. That’s why Kenco Engineering has developed our long-life flight designs to replicate the original manufacturer’s shape, profile and carrying capacity. Having said that, it’s not the type of flight that makes a plant run to the designed efficiency, it’s maintaining the designed shape or veil effect throughout the entire life of the flight. “As flights wear or fail, the volume of material creating the veil changes,” he continued. “That alters the veil density and that has a direct effect on the exhaust gas temperature, generally requiring the plant operator to raise the temperature of exit gases in an attempt to bring the stone to its required temp. Always keep in mind the exhaust gas temp is a delicate balance between many factors and reducing the exhaust gas temp too low can be detrimental to baghouse operations and create another set of problems.”


Technology Beefs up Winter Road Maintenance State DOTs use new equipment, eco-solutions, more to battle winter from American Association of State Highway and Transportation Officials


efore Christmas, large portions of North America had already recorded significant snowfall and freezing temperatures. This presented a challenge to cash-strapped state departments of transportation (DOTs). One of a state DOT’s many responsibilities is keeping the roads clear of snow and ice— despite financial hardships. Producers and contractors aren’t the only entities turning to new technology to deal with financial crises these days. Many state DOTs have found ways to put new technology and environmentally sensitive solutions to work cutting costs and improving efficiency as they strive to maintain a high level of service during this winter season. The National Weather Service says a “La Nina” pattern is at least partially responsible for the severe start to winter in many states this year. The agency predicts this weather pattern could cause a second consecutive year of record snowfall in many parts of the United States. “We called it Snowmageddon,” John Horsley said. He’s the executive director of the American Association of State Highway and Transportation Officials (AASHTO). “In February 2010, after months of bad weather, a monster snowstorm buried the Mid-Atlantic states in more than 2 feet of snow. No one can say if it’ll happen again; however, I can say with confidence that our states are as ready as they can possibly be.” Examples of state DOTs’ innovative approaches to winter maintenance include everything from new equipment to new monitoring. For instance, the Utah DOT recently installed 17 HomeView Technologies road-condition-monitoring cameras at remote locations throughout the state. The solar-powered system uses state-of-the-art, low-cost Web cameras, high-speed wireless communication, and infrared sensors to broadcast video from distant mountain passes or other problem areas. Now, instead of sending a snowplow to investigate a location, supervisors can take a quick look and decide whether an area needs to be plowed. “So far this winter, we have a net cost savings of about $200,000 using this system,” Lynn Bernhard, UDOT operations program manager said. 28 february 2011

The Colorado DOT has deployed 222 snowplows statewide, equipped with a Maintenance Decision Support System, which combines advanced weather and roadcondition prediction as well as rules of practice to help operators determine the proper application of anti-icing and deicing chemicals on a route-by-route basis. CDOT is also using automatic deicing systems to spray liquid deicers once on-site sensors detect a decrease in surface temperatures and an increase in moisture. This season, more than a dozen state DOTs will use a 26-foot-wide tow plow that is pulled behind a conventional plow truck, allowing two interstate travel lanes to be cleared and treated in a single pass. The original design for the tow plow was the brainchild of a Missouri DOT employee who applied his knowledge of farm equipment to snowplows. MoDOT worked with a snowplow contractor to design and build the version in use today. The Connecticut DOT has taken delivery of their first Bagela asphalt recycler, which they’ll use to recycle existing piles of discarded asphalt to repair state roadways this winter. The Bagela recycler is designed to recycle HMA for a total cost of under $25 per ton, saving Connecticut several hundreds of thousands of dollars per year. The Tennessee DOT will use a substance called Magic Salt to help melt ice and snow during lower temperatures. Magic Salt, made from potato juice, is a biodegradable, non-corrosive and environmentally friendly substance. TDOT and several other states including Maryland will also use beet juice to improve snow and ice removal from roadways when temperatures fall. TDOT is also adding 10 new 14-foot snowplows across the state. The plows are more than 4 feet wider than traditional plows and have the ability to clear an entire travel lane in one pass. Some TDOT trucks will be fitted with new, underbody plows that are being tested for the capability to remove hard-packed ice from the roadway. The California DOT (Caltrans) and other state agencies that respond to emergencies within California will use WeatherShare, a new Webbased tool that sends alerts, warnings, and

advisories (depending on the level of danger) for fog, ice, winds, fire and more. The system downloads National Weather Service forecast warnings and alerts every 15 minutes and sends weather data to Caltrans’ transportation management center operators, maintenance staff and other agencies such as Emergency Medical Services and the California Department of Forestry and Fire Protection. Users can easily gather more information about a specific location or a statewide region through WeatherShare’s easy-to-use online maps. “Innovation is critical. And so is efficiency,” Horsley said. “Part of AASHTO’s mission is to help install new technologies as they become market-ready. We accomplish this objective through an AASHTO committee called the Technology Implementation Group, which helped to deploy the Maintenance Decision Support System and the tow plow. States suffered a major financial blow last year due to record-setting storms and blizzards, and all indications are state budgets will remain tight throughout 2011.” Last winter, for example, the Virginia DOT budgeted $94 million and spent more than $250 million on snow removal. Tennessee DOT spent more than $23 million during the 2009-10 winter season, double the cost of the previous year. Arizona DOT spent $9 million for snow removal last season, nearly $6 million more than it typically spends. Arizona also paid an additional $16 million to repair damage done to the state’s roads and bridges during the winter season. State DOTs also encourage motorists to do their part to keep roads clear and drivers safe. When major storms are forecast, drivers should visit state DOT websites for the latest traveler information. Most states also offer 511 information lines and Twitter alerts. Citizens should also plan to stay off the roadways during major snow events to give more room to the plow trucks. They should also keep a set of chains in their vehicle and install them when necessary for adequate tire traction. Motorists should carry an emergency kit with items such as water, food, blankets, battery-operated radio, shovel, ice scraper, and flashlight.

Innovation Spreads to Funding


by AsphaltPro Staff

ublic-Private Partnerships (PPP) for project funding may be gaining in popularity, but Marc Scribner, land-use and transportation policy analyst with Competitive Enterprise Institute, Washington, has found that the PPP growth as of late has mixed results for society. Specifically, CEI reported, Scribner found that its use is increasing efficiency in the transportation sector while having a negative effect on real estate development. “In the case of surface transportation infrastructure, innovative new private-sector financing, management and ownership regimes have much to offer in terms of minimizing taxpayer exposure to risk, capturing user revenues and creating an efficient transport network,” Scribner explained. “A responsible path forward would be to utilize PPPs in surface transportation infrastructure development and management, while cutting bureaucratic impediments such as land-use regulations and business licensing to promote redevelopment. In essence, both require reducing political intervention and expanding market opportunities. Only when policy makers realize their own limitations will these sectors be free to maximize wealth creation that could potentially bring about a new era of American prosperity.”

he American Association of State Highway and Transportation Officials (AASHTO) has compiled a list of issues its members consider pressing at the local, state and federal levels. According to a late December press release, here are those issues that AASHTO leaders believe will be part of the “national conversation” that media, government and grass roots partners carry on during 2011. 1. Enact a long-term transportation bill to keep America moving Representative John Mica (R-Fla.) is the new chairman of the House Transportation and Infrastructure Committee and he’s stated that he’d like a new bill ready for consideration in the spring. 2. Pay for the transportation system we need AASHTO officials expect Congress to adopt a series of sustainable funding sources for transportation infrastructure, identify state and federal responsibilities for the funding of transportation, and create innovative financing options. 3. Ensure safer roads Just because fewer vehicles were on the roads in 2010 doesn’t mean deaths from traffic accidents will remain “down.” A program called Toward Zero Deaths will be unveiled in 2011, and

5. Bring modernization and new technologies to our transportation network Smart cars, smart roads and smart construction are designed to increase safety for us all. Also watch for AASHTO’s new Green Book—A Policy on Geometric Design of Highways and Streets in early summer. 6. Move freight to keep our communities more competitive in the global economy With the widening of the Panama Canal by the year 2014, ports along the eastern seaboard and in the Gulf of Mexico gear up to serve larger ships, which will place new burdens on the aging transportation system. 7. Assess increasingly assertive environmental regulations With more stringent rules to control stormwater from transportation sources, and other regs addressing air quality coming up, construction is getting more pressure. 8.

TK Controls’ Asphalt Inventory System


racking liquid asphalt cement (AC) costs requires personnel to get accurate measurements from tanks and transports. Plant operators and ground personnel can start by tossing away the chain and float mechanisms in the tank farm. The engineers at TK Controls, Inc., Ontario, N.Y., have an automated method. The Precision Asphalt Inventory System from TK Controls is designed to provide inventory measurements in large storage tanks up to plus or minus 3 mm accuracy with compensation for temperature or volume changes within the tank. Here’s how it works: First, two sensors are installed in each tank that is to be monitored. The first sensor is an Ohmart Vega precision level radar transmitter,

44 february 2011

which measures the liquid material level. It is a non-contact Radar Level Transmitter. The second sensor is typically a 50-foot assembly with six equally-spaced RTD temperature sensors, which measure the liquid material temperature in each zone. It is a Weed Instrument Co. multi-point RTD temperature probe assembly. Next, the two sensors collect data and transmit the information through a Yokogawa wireless modem on the tank to a Yokogawa MW100 Data Logger, which is located in the plant office. The Yokogawa MW100 Data Logger executes an algorithm, developed by TK Controls, which calculates average bulk temperature from the six temperature points and computes the API gravity and the exact

weight of the asphalt in the tank. The MW100 also captures the tank volume, actual measured temperatures and tank level. The data logger also sends the data through a router or Ethernet connection to the Yokogawa MW100 viewer on the plant operator’s desktop, where it is displayed graphically in real time. Management can also access the same data on the Internet through an IP address and password. The Yokogawa MD100 stores the data so it can be downloaded from the Internet or transferred in real time to any central data collection system.

PTI’s Foamer


esting warm-mix asphalt (WMA) designs in the lab gets a helping hand from the engineers at Pavement Technology Inc., Covington, Ga. The Foamer is designed to provide accurate and repeatable foamed asphalt samples in the lab and can be used in tandem with a lab mixer. Here’s how it works: First, the lab technician places a standard 1 quart or 1 gallon can of liquid asphalt cement (AC), at room temperature, in the heated and pressurized aluminum reservoir, which is mounted on load cells. The Foamer is designed to accommodate up to 14 pounds of AC. Second, the tech enters the desired asphalt temperature, up to 350 degrees F; the grams of asphalt; and the percentage of water to include in the reaction chamber on a touch-pad screen.

46 february 2011

At the operator’s command, the system heats the AC to the desired temperature and sends it to the reaction chamber. Water from an onboard water tank with a 2-gallon capacity sends water through an electronic proportional valve to the reaction chamber. The heated AC and water meet simultaneously in the reaction chamber where foaming takes place. To operate with less time spent waiting for AC to heat up, the operator can pour the AC directly into the reservoir. The reservoir is lined with a special high-temperature, disposable polymer bag, which can be discarded upon completion of foamed sample production. (No additional cleanup of The Foamer is required.) The foamed asphalt travels from the reaction chamber down an insulated tube for discharge to a waiting container or mixing

device. The entire foaming device is situated on a pneumatic cylinder, and mounted on wheels, which allows the technician to raise or lower The Foamer to accommodate water and AC loading, and foamed AC discharge height.

the last cut Stocks Influence All Energy Prices from U.S. Energy Information Administration


he Energy Information Administration (EIA) had seen the average retail price for a gallon of gas rise steadily through December, which everyone who watches travel trends expected. The largest increase in the country happened on the Gulf Coast, where retail diesel prices increased at almost twice the rate of gasoline prices. Residential heating oil prices saw increases as well. The average price at the beginning of the year had reached $3.34 per gallon, which is 46 cents more per gallon than the beginning of 2010. Wholesale heating oil prices were only 42 cents more per gallon than this time last year. The 4-cent difference isn’t all that comforting. Propane costs followed suit, showing the average residential propane price at $2.74 per gallon in early 2011. That’s 21 cents per gallon more than last year. The shiny spot in all this news is the wholesale propane prices, which showed a decrease of 5 cents per gallon compared to the Jan. 4, 2010, price of $1.47 per gallon. Propane stocks showed their seasonal decline in early January, dropping 2.7 million barrels to end at 52.6 million barrels. Considering the record snowfalls and “snow fatigue” weather forecasters discuss almost nightly, those stocks will take record hits. While consumers across the United States experience higher petroleum product prices—in part due to rising crude prices, which you can review in the Liquid Asphalt Cement Prices table below—propane consumers in the Northeast have seen regional supply issues add to overall price pressures.

propane in New England has risen to $3.28 per gallon. Central Atlantic prices are the highest in the Northeast at $3.37 per gallon. Consider this: Prices in the Midwest have experienced a 29-cent increase per gallon. In the Northeast, prices have risen more than 45 cents per gallon. Once again, price hikes in a commodity can be traced to supply interruptions. An outage early in the season on the Enterprise TE Products Pipeline (TEPPCO) that brings propane into the Northeast through New York State disrupted supply into New York State and the Central Atlantic and New England regions. The pipeline failure occurred downstream of the Watkins Glen, N.Y., terminal, which was able to remain operational, but pipeline flows to the Harford Mills, Oneonta and Selkirk terminals were curtailed. Rail and truck shipments from outside the region, as well as waterborne imports into Providence, R.I., and Newington, N.H., have thus far sustained propane stocks in the Northeast while portions of the pipeline remain out of service. In fact, propane stocks in New England fell to 39,000 barrels in mid-October, prompting companies to use truck and rail shipments from outside the region much earlier than they typically would to rebuild supply. The ongoing supply chain issues warrant monitoring, as there is potential for supply difficulties as we move deeper into the winter. Cold weather in the Northeast during December translated into five consecutive stock draws in the Central Atlantic, while New England stocks fluctuated during the month. New England propane inventories were 0.7 million barrels Dec. 31, which is 72 percent above the 5-year average. Central Atlantic inventories, at 1.6 million barrels, were 20 percent below the 5-year average. By early January, product transportation issues in the region were more pressing than relative stock levels. Enterprise had successfully completed hydrostatic testing of the portion of the pipeline between Watkins Glen, N.Y., and Marathon, N.Y., and received regulatory approval to resume operation from the Pipeline and Hazardous Materials Safety Administration (PHMSA).
