UNMATCHED SETUPAll tanks require some assembly in the field when the tank is set up. But some tank manufacturers reduce their costs by leaving numerous parts to be assembled in the field by the setup crew.

For example, we have seen competitor tanks with ladder parts that required several man-hours of assembly work by the setup crew. This allows the tank manufacturer to reduce the selling price so the buyer gets the tank for less. But the buyer pays extra after the sale.

We try to minimize the time and effort required for field setup. For example we prefabricate ladders and handrails so they require minimal assembly in the field.

And we prefabricate interconnecting piping using jigs and fixtures to standardize fit up and reduce fit up labor in the field. Moreover, standardized fit up also facilitates adding tanks in the future.

The ability to ship components without incurring shipping damage is the major consideration for

what we ship loose for field assembly. We don’t ship loose parts to save on manufacturing costs that the buyer pays for later during setup. This is just another area where our products are un-matched.

Please call today for more information.

Jigs and fixtures we use to ensure proper fit up at your plant.

What Sleepy Hollow Reminds Us About Highway FundingI don’t want to compare the members of the 113th Congress to a pack of demons, but I’m thankful for the First Amendment that lets me flirt with the implication in this column. Let’s begin.

As someone who has read Revelation and Washington Irving’s The Legend of Sleepy Hol-low, I enjoy the FOX television program Sleepy Hollow with all of its digressions. It has enough creepiness to satisfy the fiction writer in me. Then there’s an element of Ameri-can history that a British-scholar-turned-American-soldier Ichabod Crane injects into the program. The reason I bring this up this month is because Ichabod reminds us week after week that our nation is founded on noble principles. Our founding fathers, despite their human weaknesses, worked to create a three-branch system of government for us. They were thoughtful and meticulous in what they outlined for our Republic and they made it mandatory for The Congress to represent the people.

At this time, I have to say The Congress has been representing the wrong set of people. The members have been representing kindergarten children with their behavior. Will this improve with the 114th Congress elected Nov. 4? As of press time, the Republicans had gained 13 seats in the House of Representatives giving that party a majority of 243 to 178. In the Senate, the Republicans gained control and Sen. Mitch McConnell (R-Ky.) will be the Majority Leader who sets the floor agenda.

We learned in social studies or American history classes in grade school that categorical formula grants give Congress the “power” to appropriate funds for specific purposes such as building highways or airports. Congress hands the funds to the state or local government and the local entity in turn usually matches the funds to make the full payment for the project. For this federal fund matching, Congress gets to provide supervision at a federal level. That’s how federal highway funding has been working for a while now. If Missouri wants to add lanes to I-70, MoDOT coughs up half the funds to match half from the Highway Trust Fund.

But wait. The Highway Trust Fund is sinking faster than ratings for programs airing against the Sleepy Hollow timeslot on Monday nights. President Dwight D. Eisenhower gets credit for establishing this fund and the 3-cent-per-gallon fuel tax that fed it back in the ’50s, but no one in Congress acts like he or she wants to try anything new to rescue this fail-ing bank account.

An article in a recent issue of The Economist says the more optimistic among us see the near-insolvency of the Highway Trust Fund as a catalyst for forcing the next Congress and the White House to work together. When the current funding plan expires next year, they’ll have to play nice. “But flintier conservatives instead want the states to decide how to tax fuel and pay for roads, cutting out the federal government entirely.”

AsphaltPro’s owner, Chris Harrison says that’s a scary proposition, and he’s right. It’s frightening to think of throwing out the standard operating procedure that’s been in place since Ike made it so in 1956.

Let’s look at what we’re afraid of. We’re afraid of giving power to the states. Call me a Decentralist, but I have lost faith in Washington. I’ve watched the squabbling and bick-ering for years now, and it makes me ashamed of what we have representing us. ARTBA released a detailed summary of what happened election night and in it states, “While there will be no shortage of spin from both sides about what the 2014 elections mean for each party and their prospects in the 2016 presidential election, ARTBA is focused on what the makeup of the next Congress means for efforts to advance transportation leg-islation over the next two years.”

Infrastructure investment requires support from all of us. Republicans, Libertarians, Democrats, Free-will Decentralists with Apocalyptic Fiction Preferences all have to come together to support the type of policy reforms and creative thinking that will rescue the Highway Trust Fund and help secure a new, robust, fully funded highway transportation bill. I encourage everyone reading this note to get on the phone to not only congratulate your representatives, but also to let them know where you stand concerning infrastructure investment. Federal level? Fine. State level? That’s great, too. The point is highway funding should be a positive issue on the mind of every representative in the 114th Congress.

Stay Safe,

safety spotlight

Your safety program might need some touching up. As you prepare for the New Year, take a look at the

policies you have in place and the ones you still need to put in place. Look spe-cifically for voids in safety protocol where technology could leave you open to acci-dents and liability. For example, in a re-cent CAT Heavy Construction Equipment e-newsletter, the company provided the in-

dustry with an article about smart phone use on the job.

CAT Heavy Equipment News’ Oct. 14 edition reported that a survey by Sage Construction Information Technology showed 70 percent of construction pro-fessionals consider mobile technology important to their businesses. Those re-spondents revealed they plan to use mo-bile tech to access and/or share infor-

mation such as customer data, job data, schedules, photos, site plans, etc. Cater-pillar did its own survey of customers in July to discover “smart phone efficiency on the jobsite is a top area of interest.”

Some of the ways Cat sees workers us-ing mobile technologies include snap-ping pictures. “Consistently, operators and construction personnel report that they use their smart phone cameras to

GENERAl CONtRACtORS WIll iNceNtiVize, track SAFEty ONlINEAccording to a McGraw hill Financial survey of 129 general contractors, online safety training is on the rise. here are some stats from the smart Market report – safety Management in the Construction industry: identifying risks and reducing Accidents to improve site productivity and project rOi:• 67% of firms will be using online

safety training in 2015• 13% will establish measurable

safety goals with 11% of firms tracking safety metrics

• 9% will offer safety incentives• 9% of firms will use effective jobsite

safety analysis (JsA) and job hazard analysis (JHA) while 7% of firms will use site-specific training programs

• 7% of firms will include safety mitigation in the design phase of projects

document activity on the jobsite. In some cases, it’s a task completed. In other cas-es, it’s a video showing how they’ve found a work-around for a problem.”

What companies see is a time-savings. When the crew can snap a photo or take a video at the site, that “instant” com-munication or status update means a su-pervisor offsite can give feedback or help resolve an issue in a timely fashion. If there’s a change to a work order or regular maintenance is due on a piece of equip-ment, managers can zing a note to fore-men or equipment operators/mechanicsvia smart phones and tablets. That’s all good news for daily production.

That’s also good news for the bean-counters. By using time-tracking pro-grams, the business office can track labor and expenses by smart phone, tablet, ki-osks and the like. Time-in and time-out can even be verified by cameras and other smart technology.

Something Cat elaborated on in its article was the standard for ruggedness, suggesting contractors look for a device that is shock-resistance, dust proof and waterproof.• MIL-STD810E/MIL-STD810F stan-

dards are issued by the United States Army and are the highest standard for ruggedized testing of mobile gear. De-vices that meet this standard are test-ed in 24 categories that include pres-sure, temperature and shock. The de-vice must achieve the standard in all 24 to be certified “rugged.”

• IP67referstotheInternationalProtec-tion classification system that tests a device’s level of protection from solids (0 – 6) and liquids (0 – 7). If the rating is IP67 – it means the device is totally protected from dust (the “6”) and wa-ter when immersed in up to 1 meter of water for 30 minutes (the “7”).Something the Cat article didn’t ad-

dress was the liability a company takes on when handing a mobile device to an em-ployee, and then turning the employee loose on a jobsite. While the information shows an increase in technology’s role at the worksite, it doesn’t take into account the liability with that increase. D&G Seal-coating and Striping, Inc., President Gail Shaw pointed out that the foreman or su-pervisor on a job is the one that may have a smart phone in his or her pocket, but the

equipment operators and ground labor-ers have no business using cell phones or receiving calls while working. That kind of distraction is something her compa-ny is actively putting a stop to. She has recently worked with FCCI Insurance Group to prepare a distracted driving pol-icy with guidance from NHTSA, and she gave AsphaltPro permission to share the policy for others to use at their discretion (See Sidebar “Distracted Driving Policy” on page 12). Feel free to modify this pol-icy as it fits your operations, but remem-ber that you may wish to have a separate policy that forbids cell phone use for all equipment operators while working.

The team at FCCI and NHTSA provid-ed a template that fit very well for em-ployees who drive company vehicles. In the asphalt industry, off-road equipment needs its own mention. Whether you choose to incorporate that mention into the distracted driving policy or make a separate policy for heavy equipment op-eration is a decision for each individual management team.

Just because technology adds some steps to safety policy updating doesn’t mean it’s in the way. On the contrary, online servic-es assist us in the safety realm in ways you’d expect and in ways you might not expect. McGraw Hill Financial conducted a sur-vey to assess the ways general contractors view online safety training (See Sidebar at right). In the asphalt industry specifical-ly, Clarence Richard of Clarence Richard Company, Minnetonka, Minn., is having success with companies that select safety courses through his online training mod-ules. By giving clients usernames and pass-words, he allows them to access the safety courses on their own schedule and at their own pace. At this time, the clients are re-porting favorable results with page after page of positive reviews.

Of course advanced technology is man-ifest out in the field as well with ticketing kiosks, equipment cameras, and a host of real-time telematics to make jobsites saf-er for workers. When the safety director is mindful of the new technology leaking onto the jobsite through handheld devic-es or entering the work zone through stra-tegically placed backup cameras, etc., he or she can adjust company policies to in-corporate these items as appropriate.

SMARt USE ONlynot all employees are good candidates for using mobile technology at the jobsite; safety directors will want to weigh in on whether or not company policy allows smart phones in the hands of more than supervisors/foremen. here are some of the positive uses for smart phones in the construction setting:• Send a text with updates or

instructions to be relayed to the equipment operators.

• Take photos or videos to document jobsite activities such as work completed, areas of concern, property damage prior to work start-up, etc.

• Access equipment data/service information.

• Track hours/expenses.• Receive alerts concerning

equipment condition or routine maintenance times.

• Check weather conditions/alerts.

Accurate specific gravity measurements for coarse and fine aggregates are essential in designing and producing qual-ity asphalt mixes. Aggregate bulk specific gravity (Gsb) in

particular has a significant impact on voids in mineral aggregate (VMA), which is a key criterion in asphalt mix design and qual-ity assurance.

AASHTO T85 (ASTM C 127) and AASHTO T84 (ASTM C 128) are the standard test methods used to determine the spe-cific gravity of coarse and fine aggregate, respectively. Although these test methods can be performed at a reasonable cost, there is room for improvement. For instance, both test methods re-quire that samples be soaked 15 to 19 hours, which is inefficient for quality control testing. Other limitations include the meth-ods of determining the saturated surface-dry (SSD) condition. For coarse aggregate, SSD is determined visually, which can be subjective, particularly when the aggregate is highly absorp-tive. For fine aggregate, the cone and tamp method is used to determine SSD, but this technique does not work well with aggre-gate that is angular, highly absorptive, or has high dust content.

NCHRP Project 4-35 evaluated existing test methods, including modified versions of the AASHTO standards, to develop im-proved methods for testing aggregate spe-cific gravity and absorption. Accuracy, pre-cision and ruggedness were primary con-siderations, as were ease of use and the total time required for conditioning and testing. Equipment and testing cost were also taken into account, as well as the abil-ity to effectively handle a broad range of aggregate materials.

The aggregate specific gravity test meth-ods selected for the initial lab evaluation are shown below. The Gilson SG-5 Specific Gravity and Absorption System was orig-inally included as one of the selected test methods; however, a production unit was not available at the time of the study.For coarse aggregate

For combined coarse and fine aggregate•Volumetricimmersionusingphunqueflasks

Experiment 1 evaluated these test methods for several aggregate sources with a range of absorptions, particle shapes and textures. One trained operator conducted all of the testing. Based on the find-ings, six test methods were selected for further evaluation with a wider variety of aggregate types. The following three test methods were dropped from the study for these reasons:1. Rapid AASHTO T85 with CoreLok—added cost of equipment and

bags without significant improvement in the test variability2. Modification to Materials Tested in SSDetect System—repeat-

ability was not improved by removing the P200 material3. Volumetric immersion using phunque flasks for combined aggre-

gate—poor precisionFive coarse aggregate and five fine aggregate sources were tested

in Experiment 2, encompassing natural, crushed, recycled and man-ufactured materials. To evaluate precision, three operators used three different test devices for each method.

For coarse aggregate, AASHTO T85 pro-vided more repeatable and reproducible re-sults than the Phunque method. AASHTO T85 also yielded more accurate results for absorption, Gsb and Gssd. This was espe-cially true for absorptive aggregate. Anoth-er drawback to the Phunque method is that the flasks are fragile. Based on these findings, AASHTO T85 was still the best method for testing coarse aggregate specific gravity and absorption.

For fine aggregate, the modified AASHTO T84 method (removal of P200 material) and SSDetect yielded the most accurate, repeat-able and reproducible results for absorption, Gsb and Gssd. One drawback of the modi-fied AASHTO T84 procedure is that another test is required to measure the specific grav-

ity of the P200 material. Advantages of the SSDetect system are that it measures the full gradation of fine aggregate, it removes subjec-tivity by using infrared light to determine the SSD condition, and it can be completed in substantially less time than the modified AAS-HTO T84 method (one day instead of three). However, the equip-ment cost for the SSDetect (approximately $7,000) is considerably higher. For fine aggregate with less than 10 percent P200 material, the standard AASHTO T84 method yielded acceptable results. The Phunque method yielded less accurate measurements, and as noted before, the flasks were not very durable. Based on these findings, the Modified AASHTO T84 and SSDetect methods were recommended for testing fine aggregate specific gravity and absorption.

To reduce testing time for AASHTO T84 and T85, Experiment 3 evaluated other methods for drying and soaking aggregate samples. Alternatives to oven-drying include vacuum-drying and beginning the testing with the sample in its in-situ moisture

condition. The results for aggregate tested in the in-situ mois-ture condition were closer to the results of the oven-dried aggre-gate, but some materials still yielded statistically significant dif-ferences. The vacuum-drying method was unable to completely dry highly absorptive aggregate.

The standard 15-hour soaking method was also compared with vacuum-soaking for 5, 10 and 15 minutes (similar to the vacuum saturation method in AASHTO T 209). Vacuum-soaking for 10 minutes yielded Gsb results that were comparable to those measured using the 15-hour soaking method for both coarse and fine aggregate. This modification con-siderably reduces testing time, which is es-pecially important for QA testing.

Experiment 4 investigated the impact of P200 materials both with and without clay on AASHTO T84 test results. Results showed that if the material does not con-tain absorptive clays, including the P200 fraction, it does not sig-nificantly affect AASHTO T84 results. However, when P200 is more than 10 percent, including the P200 fraction may result in lower absorption due to over-drying of the sample to reach SSD condition. When highly absorptive clays are present, erroneous AASHTO T84 results can occur. Thus, it was recommended that the P200 fraction be tested separately (ASTM C 110 or AASH-

TO T 133) when the sand equivalent value is less than 75 percent. However, this sand equivalent value was based on limited data and needs further verification.

Proposed changes based on the findings of these experiments were incorporated into the procedures for AASHTO T85 and T84, and a ruggedness study then evaluated the sensitivity of the test methods to potential variations in operating and environ-mental parameters. Seven sources of variation that could affect

test results were evaluated at minimum and maximum anticipated levels using multiple coarse and fine aggregates with low and high absorption. The variables in-cluded parameters such as soak time, wa-ter temperature and distribution of blows in the cone tamp test. Three labs partic-ipated in the ruggedness study: NCAT, AASHTO Advanced Pavement Research Laboratory (AAPRL), and the National In-

stitute for Science and Technology (NIST). The findings were used to establish suitable ranges for operating parameters and minimize sources of variation within the test procedures, ensur-ing more precise test results.The following modifications were proposed for AASHTO T85:• Agency and contractor testing should be conducted on the

In 1977, two brothers envisioned own-ing a company. With two employees, one backhoe and a handshake, Shaw

Brothers Construction was formed. The same founding principles of work hard, satisfy the customer, and respect the peo-ple you work with still guide the company today. Since its humble beginning, Shaw Brothers Construction has grown into one of Southern Maine’s largest earth-work contractors for site development, heavy/highwayandutilityprojects.ShawBrothers also provides the area with qual-ity aggregates from its various gravel pit and quarry locations. With the addition of an asphalt plant featuring new technol-ogy, the company is now operating what is arguably the greenest plant in Maine. At the helm, brother Jon and Dan Shaw continue to manage the day-to-day op-erations, now providing their customers with a variety of asphalt mixes.

After 18 months of research, design, purchase and installation, Shaw Brothers launched its new Astec 400 ton per hour stationary asphalt plant in May 2014. The plant is installed at Shaw Brothers’ head-quarters in Gorham, Maine, and runs on natural gas. It processes aggregate from the company’s Brickyard Quarry, also lo-cated on site.

shaw Brothers’ new Astec asphalt plant is located at its headquarters on route 237 in Gorham, Maine.

tOp leFt: An upsized 80,000-CFM three-mod reverse pulse baghouse reduces dust. tOp riGht: the Astec 400 tph stationary plant has an eight-bin cold feed system to facilitate a variety of mix designs. BOttOM leFt: shaw Brothers uses ½-inch rAp in some mixes. BOttOM riGht: For customers who want a custom mix, shaw Broth-ers has fine rAp in a separate stockpile.

“By locating the new plant by one of our quarries, we lower trucking emissions,” Jon Shaw, co-owner of Shaw Brothers Construction said. “Running the plant on natural gas also minimizes emissions and reduces cost, making the plant eco-friendly.”

Co-owner Dan Shaw said: “It was im-portant to us to have an asphalt plant with the latest technology, not only for the production of quality mix, but to mini-mize our impact on the community with

respect to emissions and noise. We want-ed to be able to maximize the amount of recycle in our mixes to be a good environ-mental steward of our resources. Astec’s innovative approach to being ‘green’ met our expectations.”

Shaw Brothers’ new asphalt plant fea-tures the V-Pack™ Stack Temperature Control System and the Double Barrel® drum mixer with patented warm mix sys-tem. The V-Pack system consists of V-flights. The flights are designed to pro-

duce a uniform veil of virgin aggregate across the drum no matter how much ma-terial is in the drum, or what the produc-tion rate is, or how much reclaimed as-phalt pavement (RAP) is used in the mix. Because the V-flights shower material uniformly, they don’t leave a hole in the veil. More revolutions per minute place more aggregate in the air.

inlet as the primary reference for con-trol. As the exhaust gas temperature rises, the control system checks it against a set point. When the temperature exceeds the set point, the control system speeds up the drum’s rotational speed and controls tem-perature to the set point. This thickens the veil, which reduces the stack gas tempera-ture. The drum speed can be varied from a minimum of about 7 revolutions per min-ute to a maximum of about 12.

For Shaw Brothers, the V-Pack system improves production of virgin and high-RAP mixes by maintaining temperature while running at higher speeds. The Astec Double Barrel drum mixer with the warm mix system enables Shaw Brothers to use as much RAP as possible. The drum is de-signed to keep operating costs per ton of mix low while meeting stringent envi-ronmental codes. The warm mix system saves Shaw Brothers energy and reduces smoke and emissions.

project managment

The fine crew at APAC Midsouth performed a great resurfacing job for the state outside of Montgom-

ery, Ala., in late October. It takes atten-tion to details to get a 1.5-inch overlay just right, but they did it. For example, the state didn’t require a tack coat before the lift, but this company knows the value of get-ting a proper CR tack application down for best bonding. They rented an Etnyre 1500-gallon distributor truck and sprayed at a .05 application rate. They followed up

with a CAT 1000 paver with a 1020B screed and Topcon ski with four trackers. They paved 40 feet per minute to stay with the plant, which ran about 190 tons per hour. These pictures tell the story of how the team patched and leveled 500 tons, then placed 4,500 tons of 424A top lift with a ½-inchstoneand3/8-minusRAP.

BelOW: When it’s time to lock up the end of a pass at the end of the shift, the team works together to get it right without picking up any dirt or debris from the side of the road. this particular crew has been working together for nearly 20 years; the team members know each other and how to work together toward a common goal.

ABOVe leFt: While the core of the plant is an older model Gencor, many parts and pieces come together to complete this facility. the control house looks out over a network of systems that create the whole. ABOVe riGht: the state didn’t require a tack coat for this project, but ApAC Midsouth includes this important step. research ongoing at the national Center for Asphalt technology (nCAt) test track at Auburn university shows a tack coat prior to overlay gives extra strength against shearing forces. this extra detail gives the project its extra top quality performance.

ABOVe leFt: the dump man uses the release agent to spritz the tires and signals to the haul truck driver that he’s good to go. it’s always wise to work out a set of signals that the dump man, paver operator and haul truck drivers will use throughout the project so communication stays smooth, efficient and safe. ABOVe riGht: never underestimate the importance of reflective lights—even during the day. this crew has a reflector on the end of the ski where passing motorists should see it.

the yellow arrows in this image bring attention to some modifications the crew has made to the back of the paver. First, notice the red, 3-gallon spray container under the right-pointing arrow. this container has a bio-degradable release agent or solvent for use with tools and equipment. the crew uses it instead of an open bucket of release agent, which can slosh around or spill during the shift. to the right of the red container is an arrow pointing up to an open framework that the mechanic welded into place for the laborers. here the workers store shovels and can lean the long-handled lutes and rakes against the frame to keep such tools out of the way when they’re not in use. this helps prevent a tripping hazard and also keeps tools handy. the top arrow is pointing to a white canvas bag, which is sturdy like a feed bag and is hanging by a length of chain to keep it in place, yet loose enough to open easily. the crew stores the starter plates in this bag, keep-ing them safe from damage, out of harm’s way and in easy reach.


The average traveling motorist probably doesn’t look back and reflect upon which type of pavement he’s traveling on, or

what took place during construction that con-tributed to the pothole he just hit. What this per-son does notice more often than not is the rough-ness of the pavement he’s driving on at the time. Generally speaking, a roadway user will notice a rough pavement more so than a smooth one due to the difference in conditions the driver experi-ences in the handling of the vehicle. Highway en-gineers realized this in the early 1980s and they identified road roughness as the primary indica-tor of the value of a highway network to the road users. Over the last several decades, there have been many studies done related to pavement roughness and its effects on a variety of topics. The outcome of most of these studies tells us that a smooth pavement surface is better than a rough one; thus the advent of roadway smoothness criteria.

Roadway smoothness is generally measured by the roughness of a pavement surface by tracking changes in elevation over a given distance. Since its imple-mentation by the Federal Highway Administration (FHWA), the Internation-al Roughness Index (IRI) has become a common measurement for evaluating the pavement performance of the National Highway System (NHS). In 1998, the FHWA established a Mobility Goal to, according to its website, “increase the percentage of miles on the NHS that meet owner-agency managed pave-ment performance for acceptable ride quality to 93% within 10 years.”

This was defined as IRI values less than or equal to 170 inches of rough-ness/mile.“In2006, thisgoalwas furthermodifiedtomakegoodridequal-ity,NHS roadswith the reported IRIof 95 inches/mile (or less), as thepri-maryperformancetargetandthesecondaryperformancetarget,170inches/mile (or less).” According to the FHWA, “To increase ride quality, an owner-agency needs to build the pavements better initially because pavements built smoother initially, last longer and continue to preserve existing pavement in good condition.”

Since the Mobility Goal was initiated, owner-agencies have responded by adopt-ing and implementing specs that require smooth roads be constructed. Texas for ex-ample began measuring IRI with high speed inertial profilers in 2002, and has since developed criteria for a variety of pavement surfaces. A common pavement for ru-ral roadways in areas of Texas consists of a section of flexible base with a three-lay-er chip seal application placed on top as the surface course of the pavement sec-tion. [Note that many Texans refer to this as a sealcoat.] Texas DOT requires IRI valueslessthan125inches/mileafterthechipsealiscompleted.Initiallythispre-sented contractors with a dilemma; how were they to correct deficiencies of an in-placechipsealshouldIRIvaluesbegreaterthan125inches/mile?Typicallyonaproj-ect such as this, one contractor would prepare the flexible base, while another con-tractor provided the chip seal. This alone could create an issue where one contrac-tor would blame the other concerning who is responsible for the overall ride quality.

This problem is easily remedied, Duaine Covert explained. He’s the vice-presi-dent of RoadTrac, Inc., which provides inertial road profiling services for ride qual-ity. Covert stated that “profiling the flexible base prior to the sealcoat will tell both

contractors what the ride quality actually is and enables them to make adjust-ments accordingly.” Approximately half of the profiles performed by RoadTrac are on base material. Covert went on to explain that if the base contractor can achieve IRIvalues less than100 inches/mile, thesealcoatcontractorcan thenfeel confident about not exceeding the limit required by the specs. Contractors have stepped up to the plate, becoming quite good at placing the flexible base and achieving good IRI values.

Delhur Industries out of Andrews, Texas, is one contractor that was able to achieve IRI values in the 40s and 50s on the base course for their SH 349 proj-ect in Martin County, Texas. These IRI values are extremely low for a base ma-terial, as a typical lift of hot mix asphalt pavement criteria requires values less than60inches/miletoachieveabonus.ThoughhavinglowIRIvaluesisagoodindicator of smoothness, it may not be ideal for adhesion of the subsequent seal coat material being placed over it.

Rick Hurworth, vice president of Delhur Industries concurs, stating “smoothness is almost a detriment for base, as too smooth of a base may pres-ent adhesion issues causing the materials to push and shove.” Hurworth rec-ommended having some surface texture to assist with adhesion and that while IRI values are important criteria to meet, there are no incentives for having thosevalueslessthantherequirementof125inches/mile.

The inertial profiler has become a quality control tool for contractors to use in a variety of ways to assist in improving roadway smoothness. Lane Con-struction in Justin Texas is another contractor putting the profiler to work prior to beginning construction on certain types of projects. Richard Shu-man, a superintendent for Lane has RoadTrac perform a pre-analysis test to determine the existing conditions. He believes having the initial data assists

him in knowing what the current condition of the roadway is and developing a plan to improve that roadway during construction. It takes meticulous planning to achieve the desired results in a pav-ing operation.

“You are your own worst enemy at times,” Shu-man stated. He said balancing production with delivery and laydown, and having consistency throughout the operations are keys to providing a smooth quality road for the public.

In learning and evaluating what others do to improve quality it can lead to additional ideas and areas where improvements can be made in our construction activities. For consideration, let’s say Contractor XYZ has just been awarded a con-tract to reconstruct a section of roadway. This contractor elects to perform smoothness testing on the base material, and each additional lift of

asphalt pavement placed above it. According to the TxDOT Guidance Docu-ment on Ride Quality for Pavement Surfaces, “As a general rule, the roughness (IRI value) can be reduced approximately 50% with each lift of hot mix; how-ever, there is a point of diminishing returns once the IRI values get below 60. Typically an IRI value less than 60 is considered excellent and an IRI greater than 95 requires corrective action.” Knowing this information, and the fact IRI values can be less than a 60 on the base course, a contractor could potentially buildapavementwithIRIvalueslessthan30inches/mileandachievefullbo-nus on the project. Using best practices and having a little ingenuity is what it takes to drive quality throughout our construction processes.

As discussed at length in the new book A Whole New Engineer, to over-come a society’s view of how some-

thing is done takes years of work. The au-thors make it clear that you can’t necessari-ly change overnight the way academic insti-tutions teach students. For the construction industry, and the asphalt sector in particu-lar, we have changes to make to attract good workers who will bolster a fine road-building community. From the engineers who design infrastructure and assign materials for build-ing our roads, to the inspectors who check the quality at the end of the projects, and all the many workers in between, this industry has a proud heritage to build upon. Are we sharing that heritage and all that it implies with the upcoming labor force?

Author Dave Goldberg shared with me a brilliant insight concerning the divide our blue collar versus white collar terminolo-gy sets up. Before we get to his idea, let’s do away with the color of the collar.

I’ve mentioned in past editorial columns for this magazine my propensity for reading Little House on the Prairie books. I’ll men-tion again that the patriarch of the family, Charles Ingalls told his children there was no reason to be ashamed of any job. As long as a man was working to provide for his family, he could hold his head high.

Goldberg’s insight went further back in time than the prairie days of North Ameri-ca. He mentioned that the great thinkers of Greece and Rome were revered; the aristoc-racy paid them to think and teach their chil-dren, while servants and slaves carried out the acts of making and building. Working with your hands and creating something pe-destrian was a chore for the lower classes.

Today’s companies, be they conglomer-ates or family-owned, need to change the subconscious mindset of designating the building jobs to the lower classes. In today’s society, how can we even think there are classes lower than any other? We’re all on this planet together. There is an obvious hi-erarchy of skills and responsibility within a company. That’s why we have managers to designate tasks. We can’t make the mistake of thinking those managers are more impor-

tant as people than the individuals perform-ing the tasks.

If we run out of laborers willing to join the road-building community, the economy stops for all of us. If we run out of engineers willing to find the best way to modify, blend and place the best materials, the economy stops for all of us. To keep the economy go-ing for all of us, companies in the asphalt in-dustry must compete with the sexier mar-ketplaces for new hires.

We all realize that young men and women graduating from college usually have loads of debt. They’re eager to find jobs, but news report after news report bemoans the lack of jobs in various markets. News segments show new graduates in studio apartments or parents’ spare bedrooms chatting nervous-ly about restaurant jobs that they fear won’t let them pay off student loans on a long-term basis. Strangely enough, none of the articles I’ve read nor the news coverage I’ve seen on the topic has offered the road-building in-dustry as an option for these worried grad-uates. Given the amount of road work to be done, it seems the media is doing these grad-uates a disservice.

For example, I’ve been assisting a local asphalt-related company to find additional workers for one of its crews. The company has projects ready to work on each day of the week and often on Saturdays with signed or-ders coming in on an almost daily basis add-ing more to the expanding calendar. The job description asks for a quality-minded indi-vidual who is willing to learn on the job and grow with the company, expanding what skills he or she brings to the post. In other words, the company isn’t asking the person to be proficient at asphalt paving and com-paction in the beginning. What I’ve found disheartening—what the general labor staffing service and the Employ Florida job search customer service representative have discussed with me—is the lack of interested applicants.

When visiting the Employ Florida web-site in October, one could see there were hundreds of jobs available in general labor for pavement in this area of the state, but far more people in this area seeking jobs. It sur-prised me at first that those people weren’t

applying for the open positions in a company that pays well, has regular work all year and has been growing for years.

The October jobs report mirrored this on a national level. Depending on the news source you read, you might look at the report-ed unemployment rate and think there’s not a problem in the United States. As the CEO of the National Center for Policy Awareness, Allen West reports that the workforce par-ticipation rate has been flat since April. “We must continue to be concerned that we do not have an increase in the workforce partic-ipation rate corresponding with a lowering of the unemployment rate….there are some 92 million Americans who have dropped out of the workforce and are not even counted as part of the unemployment calculation.”

Even though there are many people who seek employment, companies will find that they have good workers already in the indus-try to keep in the industry. When a crew has been working together for a number of sea-sons and the members of that crew know each other’s habits and movements, you have an advantage over the new or disor-ganized company down the street. Veteran employees are worth their weight in gold. They’re instrumental in training new hires and making that transition into the crew smooth for the new person.

When you lose a veteran employee either to retirement or to a new direction in his or her life, it’s a blow to the company. For ex-ample, when long-time employee Rui Vila-

marim made a change and moved clear across the country, Brox Industries had a pretty big gap of knowledge to fill. Of course Vilamarim had worked with the members of the crew he supervised, training and teaching before he moved away. Brox managers were pleased when Vilamarim had the opportunity to move back to his roots, and we’re going to take a closer look at that journey in next month’s issue. While Brox, and companies like it, can put out the call for extra laborers, the work force may not respond as quickly or as usefully as we’d want.

I’d like to suggest that members of the construction indus-try remind students in colleges, high schools and even grade schools that building something with your hands is reward-ing and fulfilling. The designers and builders of the interstate highway system truly changed the face of our nation. When terrorists attacked our country one horrible September day and all air traffic was grounded, the ribbons of highways and bridges that our state DOTs continue to maintain were the byways that kept us moving and our economy on track. It’s a pleasure to be a part of the industry that builds and main-tains that economic power. How many other career options let you build a safe way for children to get to school and their parents to get to work? How many other career options let you stand back and gaze upon what you’ve created at the end of your shift? There’s a lot to be said for the instant gratifi-cation of building a smooth and safe pavement. I challenge each reader this month to share that sense of pride and ac-complishment with someone who is in school or with some-one who is looking for employment. One way to bring more workers into this industry is to let the upcoming workforce and the currently available workforce see the personal satis-faction and team pride we get from our jobs.

One of my fondest memories of be-coming an engineer was as a con-struction intern on a coal-fired

power plant in Shippingport, Pa., in the mid ’70s. Sometimes I would be 75 feet up, bal-ancing gingerly atop unfinished reinforced concrete walls helping shoot surveying tar-gets for equipment placement. At other times I would be in the middle of half-fin-ished asphalt-lined retention pond hold-ing a stick to ensure proper depth of asphalt spread, dodging D9 bulldozers at the same time. Most of the time there was a smile on my face, and I was (and remain) grateful for the experience.

New Boots for the Crew of the FutureI recalled these stories in connection with a conversation I had with the editor of As-phalt Pro magazine regarding the indus-try’s difficulty of finding good asphalt workers. At first I was surprised that the jobs are hard to fill, because from road and paving crews to crew-company engineer-ing and management, these are good pay-ing jobs. Why are they hard to fill?

Then my question started to answer it-self. The pecking order and status in tech-nology today has become more about com-puters, software, the web, and high tech, and less about infrastructure, routine and preventive maintenance, or mud and as-phalt on the boots. What can a tradition-al, yet crucial, industry do to compete for workers in an environment like this?

A Whole New Engineer & A Whole New Asphalt BusinessAs I reflected on the question, I was drawn to the lessons of a seven-year adventure in transforming engineering education cap-tured in a new book, A Whole New Engi-neer: The Coming Revolution in Engineer-ing Education (Threejoy Press, 2014). En-gineering education has a similar recruit-ing problem to that of the asphalt industry. Students in the United States and other af-fluent countries want to become anything but engineers (A.B.E.).

In other words, they want to go into fi-nance, medicine or law, but not engineer-ing. A Whole New Engineer ties the solu-tion to engineering education’s recruit-ing problem to the telling of new stories about engineering and engineering edu-cation to help create a new culture. In the book, we suggest that connecting to our students’ sense of passion and intrinsic motivation is a vital element to getting more kids to attend and complete engi-neering school.

In thinking about the asphalt indus-try in a similar way, it may be that like-wise, the asphalt industry has the oppor-

tunity to tell new stories about itself. In a sense the industry members can reframe the way they discuss the business to a way that will attract millennials to its ranks, thereby increasing the flow of great as-phalt workers.

tell the Good StoriesOne problem here is the idea that story-telling has anything at all to do with the very rational business of engineering ed-ucation, on the one hand, or the laying of asphalt, on the other. A Whole New Engi-neer speaks at length to the importance of emotion, culture and story in the case of a transformative engineering education. Oftentimes, educational systems attempt

to reform themselves by manipulating only the rational variables (content, cur-riculum and pedagogy), but real reform takes place when emotional, cultural and new storytelling help the schools develop a new mindset, a new way of showing up, thus creating a new culture and story to live by going forward.

In the same way, attracting new work-ers to the asphalt business may require a cultural shift that involves telling (and living) new stories about the business. In the remainder, we examine five stories that may be helpful to this end.Story #1: Asphalt is VitalThe first story is one the industry proba-bly already tells about itself, but it is im-portant to remember its importance and to work harder to emphasize story #1.

Modern research in human motivation starts with purpose. Why is asphalt im-portant to us?

Pictures of paving crews are nice, and tons-produced and miles-laid statistics are impressive, but in a very real sense, asphalt puts food on our tables, goods on our store shelves, gets us to airports, lets the airplanes take off, and lets us safely re-turn. Asphalt is a keystone of modern life.

Put another way, Asphalt is a sine qua non (“without which, nothing”) of modern life.Story #2: Asphalt Makers are CoolFor the longest time, making stuff was con-sidered low class. I’ve argued for some time that this bias against “making” in the West goes back to ancient Greek society in the 5th century BC. Back then Socrates, Plato and Aristotle educated (or corrupt-ed) sons of the wealthy to reflect and think great thoughts, but all makers were slaves.

The whole modern notion of liberal education remains infused with this bias against making (English majors don’t do team projects), but the good news is that making has become cool. 3-D printers, maker spaces, and a sense that using your hands is something that hip young people can and should do is catching on. As some of the best makers out there, members of the asphalt industry can ride the “makers wave” to more and better workers. Story #3: Asphalt is EpicOne of the innate benefits of asphalt work is its grand scope and scale. A computer or a website is a puny little device or arti-fact compared to even the smallest pav-

ing project. Major asphalt projects cross state lines or country borders and can be seen from space or by satellites. By em-phasizing the grand scale of asphalt work together with making on a scale that most people rarely experience, the industry can appeal to new workers.Story #4: Asphalt is a Team SportSeveral years ago, research by Russ Korte, now at Colorado State University, showed that the single most important variable in successful transition from school to work is connectedness. Laying asphalt is a team sport and the best crews have the best teamwork. Emphasizing this natu-ral teamwork state of asphalt affairs and using it to bring new workers on board in creative ways can lead to new hiring ad-vantages for the industry.Story #5: Asphalt Motivation Can Be IntrinsicA few years ago famed business writer Dan Pink wrote a book called Drive: The Surprising Truth of What Motivates Us in which he summarized research and corporate best practices on intrinsic mo-tivation. New and high tech companies

like Google use intrinsic motivation the-ory to attract throngs of new employees through an operating system that works on trust and employee initiative. Surpris-ingly, fear of threats and love of rewards are ineffective in motivating employees, and new techniques based on trust and honoring employee initiative are becom-ing the norm.

Traditional business, such as the asphalt industry, are sometimes at a disadvantage relative to the high tech later comers, be-cause asphalt organizational DNA was fixed in times that worked through tradi-tional hierarchy and control, and millen-nials gravitate toward workplaces with greater intrinsic motivation.

It IS IMpORtANt tO NOt oVerlook the culture AND StORIES OF tHE ASpHAlt BUSINESS AS yOU ExplORE WAyS tO AttRACt the asphalt workforce of the future.

Dillman builds tough equipment.Equipment that performs reliably for years. Equipment you can count on to produce high quality asphalt mix. Full plants. Single components. Individual parts.

Dillman gets the job done

It doesn’t have to be this way. The tech-niques of intrinsic motivation can be adapted to more traditional settings, and when this is done, it is often surprising the ways in which employee initiative can lead to both continuous and transforma-tive organizational change. Asphalt can tell a different motivational story about itself and attract and retain the new as-phalt worker.

tell New Stories & Attract New WorkersThe list of five stories above is far from complete. Moreover, although I am proud to have had asphalt on my boots, I am not an industry insider. To owners, operators, managers and current workers, I pose the following question:

What new stories or reframed stories can the asphalt industry tell about itself

that will help it compete for the asphalt worker of the future?

As you write and rewrite the employ-ment story of the business, some of the stories will be a simple matter of reframing the status quo. Some of these stories will require the industry to think and act differ-ently (like story #5), but either way, if the lessons of A Whole New Engineer are any indication, it is important to not overlook the culture and stories of the asphalt busi-ness as you explore ways to attract the as-phalt workforce of the future.

On the utility patch in Ontario, the Vögele AB 340 V screed is used in compaction mode.

46 DECEMBER 2014

Quality Paving 1994 Ltd., Kitch-ner, Ontario, performs gov-ernment road construction, in

addition to suburban residential work. “We’re 75 percent civic or government work, and the rest commercial,” Dave Tittley, president and owner of Quality Paving said. “We get the call because we can do the small and the big pavements.”

Quality serves its market niche with one paver that can adjust its size. “This smaller paver allows us to go into all kinds of places that the bigger machines can’t get to, yet it’s a big machine,” Tit-tley said. “It has the power to do road work. We can go into a subdivision and do a 23- to 26-foot roadway in two pass-es. The big machines can do that, but we can take that 13-foot screed down to 6.5 feet and do a pathway, such as a bike or golf cart…” To Tittley, the Vögele Super 1300-2 provides the best of both worlds.

Quality acquired the Super 1300-2 in spring 2013, and in late summer 2014 had some 800 hours on the machine. In late summer on a water and sewer repair at light manufacturing plant in Missis-sauga, Ont., Quality Paving was placing a final wide patch, 197 feet by 13 feet. Ap-proximately 66 short tons of hot mix as-phalt (HMA) was placed in one morning.

“The plant put in new sewer lines, and we are putting in two layers of hot mix asphalt, 2 inches of HL8 binder course, and 1.5 inches of HL3 finish course,” Tit-tley said. The HL8 lift has a maximum aggregate size of ¾ inch, and the HL3 hasamaximumaggregate sizeof 3/8 to½ inch. Some might think the size of ma-chine “overkill” for the parking lot utili-ty patch. “At the end of the day, when the equipment gives you a good quality job, it’s not overkill,” Tittley said.

International Utility By tOM Kuennen



The Super 1300-2 is paired with the AB 340 V screed from Vögele, not com-monly seen in North America. “Once we set the screed level, we hardly ever touch it,” Tittley said. “For the size of the ma-chine, it’s a very heavy duty screed, it’s as heavy as a large highway class machine.”

On the plant parking lot, the vibrat-ing screed was getting about 90 per-cent compaction ahead of finish rolling by a Hamm HD 12 CompactLine roller. “We don’t always use compaction at the screed, but on road work, we will use it,

depending on the length of the road,” Tittley said. “It helps us get compaction a little bit faster, so we don’t have to stay as long rolling.” The Hamm compactor provided a fine complement to the Su-per 1300-2, he said.

Like all Vögele screeds, the AB 340 V is electric-heated. “One of the biggest pluses of a smaller machine like the Su-per 1300-2 is that we have electric heat,” he said. “The screed is constantly heat-ed, and we always get a smooth finish, whereas a lot of small machines don’t

have that capability, instead using pro-pane burners. It’s one of the few small-er-size pavers that has the technology normally seen in a larger paver.”

The paver incorporates the Vögele Nivel-tronic Plus system for automatic grade and slope control, to achieve superior paving results. “Because we’ve been doing most-ly trenches this season, we haven’t had the need to use it,” Tittley said. “But when we do bridge work we’ll use the Niveltronic. For this trench we’re just matching to the existing pavement and don’t have it on.”

tOp: the super 1300-2 may have the horsepower and extension for roadway paving, but the Quality paving ltd crew used it in southern Ontario for a utility patch with su-perb results.

Quality feeds asphalt to the Super 1300-2 using either a dump truck or front-end loader. “We can use both, depending on what the project is,” Tittley said. “Most of the time we have our triaxles dump directly in the hopper. The 100 hp engine provides lots of power to push triaxles, tractor-trail-er dumps and flow-boys; we have no prob-lem in pushing any of them. But if we’re in a small area that a truck can’t back into, the paver is ready for a large skid-steer or even a backhoe to feed with asphalt.”

“The paver is more economical to op-erate than other pavers we’ve had, be-cause we are able to select between three different operating modes for the engine,” Tittley said. “Most of the time we keep it in Eco mode, which is eco-nomical for general use. The only time we change that is when we put the ma-chine into production. For that we have an Idle and also a Super mode, which re-ally brings the engine up when dealing with heavy asphalt loads, for example, to

push a truck whose brakes are on. Oth-erwise we can use Eco in virtually every application.”

The hopper also has an easy-to-use cleanout system, he said. “One of the best things about the Super 1300-2 is that the screed goes down to 2 me-ters wide, but the whole machine goes down to 2 meters as well,” he said. “You can go through narrow downtown al-leyways; the whole machine goes right through it.”

good idea

By the beginning of 2015, companies will be using global warning signs for danger. This is so we can travel

to any country and work without miscom-munication. Imagine if you were pick up a can in a foreign country, thinking it con-tained a release agent, and began spraying the contents on the push bar of the paver only to see the paint start flaking off and several crewmates start running toward you waving their arms in the air. What a nightmare! Language barriers can hinder safety, so greater powers than you and I

got together to create globally recogniz-able symbols for hazards.

What about simple symbols in your own backyard? A good idea that the crew from APAC Midsouth shares this month is making stickers or placards to remind workers of simple safety tips and then placing those stickers where they make sense. In this example, the crew has a reminder that you should always have three points of contact with ladders when climbing onto or off of equipment. The reminder is placed on the equipment near

the ladder. This is where it will do the most good for the workers.

Think about the areas in your yard or on your jobsites that could use easy re-minders like this to enforce safety and safe ideas. Do you want to share them on the facebook page? Go to https://www.facebook.com/AsphaltPro to join thediscussion.

Repairs for RentalsAtlas Copco service centers free up rental techs from lengthy repair, refurbishment projects

Atlas Copco Construction Equip-ment of Commerce City, Colo., has launched a unique structure

to keep rental centers profitable, efficient and operating at peak levels. The compa-ny has strategically located eight service centers within a day’s drive of the major-ity of rental customer locations across the United States.

While rental centers easily tackle the run-of-the-mill repairs and equipment maintenance, major repairs and refur-bishments can take critical time away from keeping units serviced and in the field. In addition, major repairs often re-quire specialized knowledge to complete. The Atlas Copco technicians will repair or refurbish machines and return them to the centers as quickly as possible.

By using the Atlas Copco service cen-ters for major and intense projects that could take as long as a week or more, such as clutch replacements, coupling chang-es and refurbishments, rental companies can free up their own technicians’ time so they can provide critical, responsive sup-port for their key customer segments.

Atlas Copco states it is the first equip-ment manufacturer to offer multiple ser-vice centers throughout the United States for this purpose. Its eight facilities are lo-cated in regions with high concentrations of rental companies and significant Atlas Copco equipment use. The service cen-ters are in Seattle; Corpus Christi, Texas; Covington, Ga.; Cleveland; Apex, N.C.; Santa Ana, Calif.; and Houston (with two facilities). When necessary, trucks based at those centers can service equipment in

the field. The company plans to open ad-ditional centers in Chicago, south-cen-tral Florida and in the northeast United States, as well.

As Atlas Copco has expanded its ser-vice offerings, it has kept the end goal in sight: be as close to as many customers as possible to provide timely service within a day’s travel. “We’re well on our way to this goal,” Matt Cadnum, vice president of af-termarket support at Atlas Copco Con-struction Equipment said. “With our cur-rent setup, if you drew eight 200-mile-di-ameter circles on a map, about 90 percent of rental centers would be within those circles. That’s a big footprint.”

When repair isn’t enough, Atlas Copco service centers can often refurbish equip-ment—such as compressors, generators, hydraulic attachments and road equip-

54 DECEMBER 2014

ment—to extend its life and reduce total cost of ownership. In fact, to date Atlas Copco has refurbished more than 1,000 compressors and thousands of other ma-chines. When it’s possible, refurbish-ment costs less than buying a new piece of equipment, and the end result is a reliable machine that looks nearly new and oper-ates optimally.

For example, when a piece of equip-ment is in the refurbishment “sweet spot”—between four and six years old—it will have depreciated to 20 percent of its original value. A refurbishment can bring that equipment’s value back to 80 percent of its original price. This means owners get more value and use out of their old equipment. Atlas Copco backs

up the refurbished equipment with three- to five-year warranties that are compa-rable to what the company offers on new equipment.

For Atlas Copco, offering convenient support starts with manufacturing high-quality, lasting products. Beyond that, the company also takes a proactive approach to the regions it serves; tracking what type of equipment is more popular in each of them. For example, compressors and generators are some of the top pieces of equipment rented in the oil fields of Tex-as, so Atlas Copco keeps extra compres-sor parts stocked to provide speedy ser-vice in that region.

In terms of expertise, technicians at At-las Copco service centers go through ap-proximately 80 hours of training per year. They can service not just Atlas Copco equipment, but all brands. As long as the equipment is in a class that the company manufactures—compaction equipment, compressors, generators or hydrau-lic breakers, for example—it can be ful-ly serviced and repaired in a nearby ser-vice center. In addition, Atlas Copco en-gineers are available to help when techni-cians run into particularly challenging or unfamiliar projects.

In fact, the company has added 18 sales personnel to provide local expertise and support to its rental customer base. In addition to creating a local point of con-tact, the new sales staff helps rental cen-ters find the right equipment to maxi-mize fleet use and serves as a resource for customers.

“More and more contractors are turn-ing to rental centers for cost-effective equipment solutions,” Brian Bieller said. He’s the vice president of business devel-opment for Atlas Copco. “We’ve added professionals who excel in customer ser-vice and finding practical solutions that will help rental centers serve their cus-tomers and expand their bases.”

The new staff additions are part of the overall strategy to build local relation-ships and support with rental customers and the markets they serve. The sales sup-port team now consists of 25 people dedi-cated to support the rental channel.

“We’ll have someone on the ground to answer whatever need rental centers may have,” Bieller said.

Scan ItLaser Design, Inc. (LDI), Minneapolis, Minn., has partnered with Rx Solutions of France for North American distribu-tion of the Rx Solutions’ DeskTom CT 3D Scanner. The DeskTom system is de-signed to address the need for 3D dimen-sional metrology and non-destructive testing. Let’s look at what that means for contractors:

Computed tomography (CT) scanners have the ability to scan an object’s inter-nal and external surfaces while allowing characterization of the porosity, fiber ori-entation and structure of the inner mate-rials, all within the same dataset. CT scan-ning for three-dimensional industrial measurement, inspection and modeling has seen dramatic growth the last several years. The DeskTom CT scanner from Rx Solutions is a 3D micro-tomography and digital radioscopy system that enables internal geometries of an object to be in-spected without destroying it.

The DeskTom CT scanner offered by Laser Design is compact. With power up to 150kV and a working envelope of 230 x 250 mm, the DeskTom can be used with plastics, elastomers and metallic parts. Laser Design uses Volume Graphics soft-ware for post-processing CT samples, al-lowing structural analysis of materials, porosity analysis, and fiber orientation determination, along with complete di-mensional inspection and definitions.

Enter in the FieldDexter+Chaney of Seattle offers the Spectrum Equipment Field Entry soft-ware for gathering and analyzing equip-ment data in the field. Using the app, us-ers select a job and view all equipment as-signed to it, or view the location of equip-ment in the field. The app can be used to enter data such as usage hours and odom-eter readings, and track fuel transaction or amounts of fuel dispensed. It can also track scheduled maintenance tasks, in-forming users when maintenance is due and recording when maintenance tasks are completed.

“One of the biggest benefits of the Equip-ment Field Entry app is the ability to track fuel usage and gather data to get better con-trol of fuel costs,” John Chaney said. “Fuel itself can amount to as much as one-third of operating expenses on equipment. Most companies have not had a simple, effective way to accurately gauge fuel readings and therefore many make rough projections or lump fuel costs together as overhead.

“With Equipment Field Entry, that data can be easily gathered and equipment man-agers can get accurate, up-to-date utili-zation rates for equipment, stay on top of maintenance, and manage equipment more effectively and efficiently overall.”

The Equipment Field Entry app connects directly to Dexter+Chaney’s Spectrum Construction Software suite. The app can also work offline and sync with Spectrum when connected to the Internet. The app includes Bluetooth capability that enables

it to automatically connect and communi-cate with fuel tank flow meters.

“We recognize the need for better data gathering in the field and better communication of that data with the office,” Chaney said. “If equipment

V-pack gets patentAstec, Inc., of Chattanooga, has been award-ed patent number 8,863,404 for its V-Pack Stack Temperature Control System. The sys-tem is designed to extend the range of mixes that can be produced without requiring the flights in the drum be adjusted. The system’s “V-flights,” which are unique drum flights with a deep V-shape, and its use of variable frequency drives (VFDs), which provide control of the drum rotational speed, are

keys to the control system managing an as-phalt plant’s exhaust gas temperature and increasing overall efficiency.

The Stack Temperature Control System is designed to automatically control ex-haust gas temperature across a range of mix types and operating conditions by making drum speed changes. The system keeps bag-house temperature relatively stable as mix temperature changes and even as mix types change from hot mix to warm mix, from vir-gin to high RAP, and from dense graded to

open graded mixes. These kinds of produc-tion changes could cause baghouse tem-peraturechangesofmorethan100°F(38°C) without the V-Pack Stack Temperature Control System.

Astec’s V-Pack Stack Temperature Con-trol System uses the V-flights to produce a uniform veil of aggregate across the entire drum, regardless of how full the drum is, the plant’s production rate, or the RAP percent-age used, according to the manufacturer. This is what enables drum speed changes to be effective as a means of controlling stack temperature. Because the V-flights shower uniformly without regard to how much ma-terial is in them, they should never leave a hole in the veil.

The V-Pack Stack Temperature Con-trol System monitors the exhaust gas tem-peratures at the baghouse inlet as the pri-mary reference for control. As the exhaust gas temperature rises, the control system checks it against a set point. When the tem-perature exceeds the set point, the control system speeds up the drum rotation, which controls temperature to the set point. The drum speed can be varied by the system from a minimum of about 7 rpm to a maxi-mum of about 12 rpm (8 rpm is the normal speed for Astec drums without this system).

Applications of the V-Pack Stack Temper-ature Control System enable Astec to pro-vide asphalt plants that produce mix with RAP content from 0 to 70 percent without any physical changes to flights or other plant equipment and without loss of production rate capacity or fuel efficiency, according to the manufacturer. Astec plants so equipped are also able to produce dense graded virgin mixes and open graded friction course. See related article on page 14.

Crush the WebIROCK Crushers of Valley View, Ohio, has updated its website at www.irockcrushers.com to make it easier for dealers to meet cus-tomer needs. While customers can see the

parts, the new portal is password protected so only dealers can view certain materials. With access to pricing info, literature, parts catalogs, sell sheets and spec sheets that con-tain proprietary data, dealers should have an easier time of placing orders over the phone. In addition, the portal features a library of instructional videos on adjusting aprons, changing blow bars, and performing oth-er wear-part change outs and maintenance. Dealers can register for warranties and make claims through the portal as well.


here's how it works

Roundup SmoothnessSmoothness is still a hot topic in the paving

realm. The tried and true process for mea-suring fuel-saving asphalt pavements starts

with a device that rolls along the pavement. Or does it? OEMs also have devices that shoot lasers to and from the pavement to get readings of bumps, dips or imperfections. The SurPRO 3500 from Inter-national Cybernetics Corporation, Largo, Fla., is a rolling surface profiler (top). The operator walks behind the device at a nominal speed of 1.25 miles per hour and a maximum speed of 2.5 miles per hour, pushing it along a straight line of the pave-ment to be measured. Wheels of 6 inches in diame-ter use an inertial stabilizer to stabilize the unit and a 12 VDC battery powers the unit. It takes readings of the pavement at a rate of 1,000 samples per sec-ond, 900 samples per minute or 1.1 millimeter per sample at user-specified intervals. ICC SurPRO utility software interacts with the onboard com-puter so the operator can view data onsite and then save and transfer data to a computer or notebook.

The Connected Site® Solution from Trimble, Sunnyvale, Calif., also offers a communication tool for enhancing smoothness (middle). Within the system, the Trimble CCS900 Compaction Control System software uses the smart antenna to read and collect data from the asphalt mat. It sends that data through a protected, flexible cable and “tells” the Trimble CB460—or CB450—in-cab control box where cool spots occur.

Also at the compactor, the EZ-Temp I from Clar-ence Richard Company, Minnetonka, Minn., uses infrared technology to read surface temperatures and then transmit the measurements directly to the person who needs them (bottom). When the roller operator is ready to begin his rolling pat-tern, he turns on the system with the knob located on the left side of the EZ-Temp I box at his operat-ing station. The infrared sensor continuously mea-sures the temperature of the surface and sends the measurement to the EZ-Temp I display at the op-erator’s station. The operator watches the fluctua-tion in mat temperature while moving through the rolling zone and rolling pattern.

For more information on the SurPRO 3500 profil-er, contact (727) 547-0696 or [email protected]. For more information on the Connect-ed Site® Solution, contact a Trimble representative at (800) 361-1249. For more information on the EZ-Temp I, contact Clarence Richard at (800) 372-7731.

Mount EZ-Temp I display at operator’s station.

Step 1

Mount the bracket and sensor perpendicularly to the mat.

Step 2

Wire the sensor and indicator cords to the fuse box.

Step 3

The infrared sensor continuously measures mat temperature variance.

Step 1

The sensor sends temperature readings to the EZ-Temp I display.

Step 2

The operator makes rolling decisions based on real-time temperatures in the rolling zone.

Step 3

How To Install It How It Works

The worker calibrates the SurPRO 3500 with a calibration level.

Step 1

The worker pushes the SurPRO 3500 along the surface to be measured. She walks at a nominal speed of 1.25 MPH up to 2.5 MPH for best results.

Step 2

The SurPRO 3500 takes pavement readings at a rate of 1,000 samples per second.

Step 3

The operator uses software to analyze data and views the road profile.

Step 5ICC SurPRO Utility software interacts with the onboard computer.

Step 4

The Trimble MS972 GNSS smart antenna transfers data through the Trimble SNM940 Connected Site Gateway...

Step 1

...to the office for analysis.

Step 2

If the GPS manager or project supervisor sees a fluctuation, he can log into the machine remotely to assist the operator.

Step 3

Place the Trimble SPS855 GNSS modular receiver in a location with clear visibility to the sky.

The Trimble CB460 control box communicates information to the roller operator from the MS972 GNSS smart antenna.

Supply and DemandIt’s a basic economic lesson we are all fa-

miliar with and current low demand could mean lower fuel prices for asphalt produc-

ers. Robust supply at a time of potentially weak-ening demand continues to put downward pres-sure on crude oil prices. Libyan production aver-aged 800,000 bbl/d in September and at timesreached higher levels, while other OPEC produc-ing countries have not lowered production oth-er than to offset the seasonal drop in demand. Meanwhile, a weaker economic outlook out-side the United States also signals reduced oil demand, which is reflected in recent strong in-creases in the value of the U.S. dollar.

In addition, the Energy Information Adminis-tration projects average U.S. household expendi-tures for natural gas, heating oil, electricity, and propane will decrease this winter heating sea-son (October 1 through March 31) compared with last winter, which was 11% colder than the previ-ous 10-year average nationally. Projected average household expenditures for propane and heating oil are 27% and 15% lower, respectively, because of lower heating demand and prices. Lower heating demand and higher prices contribute to natural gas and electricity expenditures that are 5% and 2% lower than last winter

Driven in large part by falling crude oil prices, U.S. regular gasoline retail prices fell to an aver-ageof$3.41/gallon(gal)inSeptember,29centsbe-low the June average. U.S. regular gasoline retail prices are projected to continue to decline to an averageof$3.14/galinDecember.TheEIAexpectsU.S. regular gasoline retail prices, which averaged $3.51/gal in2013, toaverage$3.45/gal in2014and$3.38/galin2015.

Additionally, weaker global demand helped North Sea Brent crude oil spot prices fall to an average of $97 per barrel (bbl) in September, the first month Brentpriceshaveaveragedbelow$100/bblinmorethan two years. Brent crude oil prices are projected toaverage$98/bblinfourth-quarter2014and$102/bbl in 2015, according to the EIA.

Total U.S. crude oil production averaged an esti-mated8.7millionbarrelsperday(bbl/d)inSeptem-ber, the highest monthly production since July 1986. Total crude oil production, which averaged 7.4 mil-lionbbl/din2013,isexpectedtoaverage9.5millionbbl/d in 2015. If realized, the 2015 forecastwouldbe the highest annual average crude oil production since 1970.
