Which of the state asphalt association meetings or national expos will you, personally, attend this year? Do you have a ticket to travel to the legislative fly-in this fall? The transportation construction industry, and the asphalt industry in particular, needs its membership to show up. Now I can hear some folks saying, “that’s why I pay dues—so the association will do that work for me.” True. True to an extent. There’s strength in numbers. If you’re the team owner who pays the pitcher’s salary, expecting him to show up to the game, you probably have additional players on the field. Otherwise, it’s just batting practice for the other team. In the game of politics and funding, someone’s going to get the crumbs that fall from Congress’s table up there in the fancy box seats with the fancy concessions served on fancy platters. It’s worth our time to show up and make a play for the real funding that Congress owes to the transportation industry. I’ve said it before and I’ll say it again, it is the responsibility of The Congress to provide a surface transportation system in this nation. We merely need to go to Article 1 of the U.S. Constitution to find it. Start at the beginning of Section 8:

“The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and provide for the common defense and general welfare of the United States; but all duties, imposts and excises shall be uniform throughout the United States.”—Source, law.cornell.edu Of course that same article also lists one of Congress’s duties to establish roads. I’m not suggesting that we all show up at our representatives’ offices during the legislative fly-in with signs that tell them to do their jobs. I am suggesting that it is worth our time, collectively and individually, to get word to our representatives that we’re interested in seeing them follow through on fully federally funded longterm highway transportation bills (plural) that keep their constituents and this country working. I’m suggesting it’s worth your time to show up for these state and national meetings to participate fully in your business. I’ll see you there! Stay Safe,

Sandy Lender

If all our players don’t show up, it’s just batting practice for the other side.

Starting in June, every load of mix you send out needs to be accompanied by a Safety Data Sheet (SDS).

Your Mix Requires an SDS

A

s reported previously in AsphaltPro, the goal of the Globally Harmonized System (GHS) is to make it quick and easy for anyone anywhere in the world to recognize a danger that a chemical may pose. The Department of Safety and Health has listed a number of

benefits from implementing an international system of communicating hazards. While the International Agency for Research on Cancer (IARC) proved asphalt fume is not a carcinogen, components associated with mixes can be deemed hazardous. Due to the presence of these

components, asphalt mixes are required to have a safety data sheet (SDS) so that each batch of mix meets the GHS requirements. The SDS must be ready and in place as of June 1. During the National Asphalt Pavement Association (NAPA) 60th annual meeting on


safety spotlight Marco Island, Fla., in late January, Chris Willis of Oldcastle Materials spoke to an audience about the implementation of the SDS at Oldcastle. The information she shared included the good news that asphalt producers won’t have to reinvent the wheel to meet the requirements. NAPA has created a “Base Asphalt Pavement Mix Safety Data Sheet” that will be available around the time this magazine is distributed in Baltimore during World of Asphalt. NAPA also has a training webinar available that walks viewers through the process of assembling the SDS. If you have a specialty product, you’ll need to modify the base SDS that NAPA has compiled, but the basic format is prepared for you. Visit www.asphaltpavement.org. In the meantime, consider the system Willis shared for complying with GHS labeling. Chemical or product suppliers are required to include a safety label on the initial shipment of a product so that each employee or worker who will have con-

You can print out an OSHA Quick Card with the Hazard Communication Standard pictograms and hazards at www.osha.gov/ publications. tact with the product has clear and full information about its potential hazards. That doesn’t mean an asphalt producer can put a safety label on the haul trucks in his in-house fleet and consider the matter solved. Customers who purchase mix and haul it away in their own trucks or hot boxes won’t have the benefit of the SDS on their conveyances. That means you must provide the label with the actual mix. Controls and loadout systems manufacturers such as B&S Light Industries and Libra Systems can help here. “Our system allows an administrator to con-

figure any safety message to print on the tickets,” Ken Cardy of Libra said. He explained that, to this point customers typically print loadout information on the front of the ticket. “Printing on the back would be more a function of the printer than the software,” he shared. “I have seen pre-printed messages on the back of tickets.” Printing the SDS label on the back of loadout tickets is the method Oldcastle found most expedient to be in compliance. Now each and every load of asphalt pavement mix that leaves an Oldcastle facility can meet regs and direct customers to a page on the company’s website with additional information. Your company may think of an additional or different way to get the SDS to accompany initial deliveries of product, but it’s good to know there’s a working model in action. Not only is this model in action, with the sample SDS upcoming from NAPA and the training webinar available, the model might be easy to replicate.

The National Asphalt Pavement Association (NAPA) announced Jan. 28 the winners of its 2014 Quality in Construction Award for excellence in construction of an asphalt pavement. For 2014, 205 projects completed by 80 companies were honored with a Quality in Construction Award. Ninety of the projects were singled out for their use of sustainable construction practices, such as incorporating reclaimed and recycled materials and using warm-mix asphalt (WMA). “Quality pavements are something every road builder strives to construct,” NAPA 2014 Chairman William C. Ensor III said. “We want to build pavements that deliver on the promise of high performance and drivability for the public. Projects that earn a Quality in Construction Award have been measured against industry best practices designed to live up to that promise.”

14 March 2015


LEFT: This pavement shows gouges in the milling pattern from irregular milling teeth. BELOW: Always use a straight edge to check your work. The level shows we have an obvious crown in the road, which we didn’t want on this particular project. The subcontractor was supposed to take out 2 inches all the way across the lane, but that’s not what happens when the cutter drum is in need of maintenance and repair. The level is supposed to be flat, not “up” 2 inches too high. The problem? There are 27 teeth and 27 holders that are worn out on the cutter, but the team didn’t know it. When I showed them the problem, they felt unable to correct it with their mechanic out of town. Empower your supervisor or foreman to make the tough calls out on the job. If the foreman had said, “stop now until this is fixed,” the team wouldn’t have wasted time, money and manpower on a poor performance that had to be redone.

Do More Than Brush Those Teeth By John Ball

H

ave you had trouble getting smoothness on a mill and fill? Look to the milling crew’s best practices. It’s shameful when a county or agency decides to merely place a thin overlay on a badly cracked concrete pavement, but it’s also a shame if a subcontractor does a poor job of preparing a milled surface for the better treatment of a mill and fill. Use the anonymous contractor’s experience here to learn some tips for the next milling job you need to do in your pavement maintenance or preservation work. Notice in these pictures that the crew is putting a crown in the road where it’s supposed to be flat—they’re not using a level and they’re not profiling. They should have been seeing a chevron pattern, a herringbone pattern. Instead, they’re seeing a mess because they haven’t been maintaining the cutter drum and teeth. When they saw a problem, the mechanic was out of town, so they just kept milling. To avoid this sort of problem, you should check the teeth every day. Nobody told them how important it is to check the teeth and the holders each day. The hardness of the aggregate really makes the teeth wear. If you don’t check over the teeth each day, you won’t know that something is going bad.


keep it up TOP LEFT: You can clearly see the tip is missing from the tooth; the next one is missing the “circle.” TOP RIGHT: This tooth just gouges the mat; it’s not rotating. BOTTOM LEFT: The tip of the tooth isn’t getting to touch the pavement; it’s not getting to do its job. Because of the worn holders and misaligned teeth, we had to re-cut almost 2 miles down the road to fix what the ineffective cutter drum had done.BOTTOM RIGHT: After re-milling the lane, we put the level down again. It looks much closer to level. This is the best way to double-check your work behind the mill. Put the 4-foot straight edge across the lane and see what you have.

This could have resulted in a great deal more material when paving if we hadn’t gone back to correct the pattern. It cost the company some money to go back and re-do the milling, but it would have cost more in material to make up the profile of the pavement to get a smooth surface.

When Astec parts salesman GREG PAINTER is not calling on customers to support their parts needs, you can find him on the water fishing or in the woods hunting. But when you call, he’ll trade that fishing hat for a hard hat, because he is always your parts man.

An ASTEC parts salesman knows that being successful in his job means that you count on him to deliver when needed. So when you need a part, he will take the call because no matter what else he is, he is always your parts man.

Anyone can stock parts and ASTEC stocks the world’s largest inventory of parts for asphalt plants. But ASTEC doesn’t just stock parts. ASTEC delivers the industry’s best customer service. That is what sets us apart.

Northeast Asphalt Takes the Big Win Sheldon G. Hayes Award for 2014 goes to Green Bay company From NAPA

N

ortheast Asphalt Inc. of Green Bay, Wis., is the winner of the 2014 Sheldon G. Hayes Award for excellence in construction of an asphalt pavement. The award, bestowed annually since 1971, recognizes the country’s highest quality highway pavement. The company received its award Jan. 28 at a ceremony during the association’s 60th annual meeting on Marco Island, Fla. Northeast Asphalt Inc. and the Wisconsin Department of Transportation Northeast Region were named the winner for Northeast Asphalt’s work on State Trunk Highway (STH) 22 from Gillet to Oconto Falls, Wis. In the spring of 2012, just prior to the start of Northeast Asphalt’s mill and overlay project, a utility conflict running along both sides of the 8.1-mile project was discovered, threatening to wreak havoc with planned completion before year’s end. “In the typical utility relocation, it would happen just prior to us coming in and doing any work,” said Ric Szalewski, Project Manager at Northeast Asphalt for the winning project. “But they were anticipating a couple of months to relocate those utilities and there was talk of delaying the project until 2013.” Everyone involved in the project came together to discuss options. In the end, innovative thinking saved the day. “We came together with our dirt contractor, Relyco Inc., to use Spar underground mapping technology, ground-penetrating radar, and advanced software to locate the utilities within a three-dimensional space,” Szalewski said. 18 March 2015

This year, the evaluators praised all the candidates for their high-quality construction practices, which resulted in smooth, safe, and durable pavements. Northeast Asphalt Inc. won the top award for its work on State Trunk Highway (STH) 22 from Gillet to Oconto Falls, Wis.

With the radar pinpointing the utilities exactly, the construction crew was able to provide a workaround solution without harming the utility lines. “They could start construction and not have to worry about interfering or damaging any utilities,” Szalewski said. “They knew the areas where the utilities crossed, so they skipped those areas. And where the utilities were running with construction, they could stay away from them or stay above them. The utility contractor could work behind the excavators to relocate the lines.” With this utility conflict solved, Northeast Asphalt was able to complete the project quickly and efficiently. The company was anxious to submit this job for a Sheldon G. Hayes award only to face another unexpected hurdle: the weather. Winning pavements of the Sheldon G. Hayes award are scrutinized only after surviving one winter season after completion. Because Northeast Asphalt’s STH 22 project was completed so late in 2012 — Oct. 30 — the company had to wait until 2013 to submit its entry. Thus, the pavement was evaluated with two winters under its belt, including the winter of 2013– 2104, one of the harshest on record. “I looked back through the records in this area, and there were 59 days during the winter when temperatures were at or below 0° Fahrenheit,” said Brett Stanton, Director of Engineering Services for

Northeast Asphalt said “That was particularly unique, and [the road] looked very good for the rough winter it went through.” Northeast Asphalt was also able to procure a cost reduction incentive (CRI) modification to the original contract. “We partnered with the Wisconsin Department of Transportation to evaluate the pavement, and we realized we could save the DOT $160,000 if we changed the pavement structure and used some of the existing materials on site,” Stanton said. While some of the materials were new, “we imported far less by utilizing what was there,” Stanton said. In the end, recycled asphalt material reduced the company’s need for virgin asphalt by 24 percent with the 12.5-mm surface design mix and 23 percent with the 19.0-mm binder mix. The Sheldon G. Hayes Award winner and finalists are determined through a rigorous two-year evaluation process. Any highway pavement project using more than 50,000 tons of asphalt is eligible for consideration. Initially, the project must win a Quality in Construction (QIC) Award. The year after a project wins a QIC Award, it is eligible for consideration for the Sheldon G. Hayes Award. The top-ranked projects from each year are tested for smoothness, and then visually inspected by an independent pavement consultant.

Plan Ahead: Where’s That Recycle Gonna Go?

W

hen the most costly product in an asphalt mix is one that can be created on-site using recycled materials, the savvy producer will find many ways to work with it. Invest in the equipment you need to fractionate your millings, crush to size those chunks of recycled pavement, etc. Fractionating the product makes sense, but have you thought about where the product goes once you have it down to size? Let’s start a discussion of metering and controlling ingredients such as recycled asphalt shingles (RAS) with tips for handling the material. Mitch Duncklee is a software engineer for Systems Equipment in Waukon, Iowa. He suggested producers 20 March 2015

could get more consistent feeding results if recycling operations stayed up to date with their practices. “Pre-processing the shingles differently can make a large difference in how the RAS feeds,” Duncklee said. “While making mix, good feedback control in the blend computer can help smooth out the AC content, but any chance to prevent manic speed changes because of poor feeding should be looked into.” He sees pre-processing as a positive step for future innovations. “Pre-processing and storage would go a long way to make RAS behave like a typical ingredient.

materials. A lot of money gets spent removing moisture and clumping in process. Why not eliminate it before it even gets to the bin?” While a recycler will look at pre-processing as sorting the deleterious materials out of the shingle pile prior to grinding shingles to produce RAS, the asphalt plant owner can look at pre-processing at his site as declumping the RAS prior to feeding it into his drum. Preston McIntyre, a sales representative for Rotochopper, once explained that clumping or compacting of RAS usually occurs in one of two ways. “When material is run over by a loader or similar piece of heavy equipment, it compacts,” McIntyre said. “Another clumping

project management occurrence can happen if a pile of RAS sits for an extended period of time; it can conglomerate due to the heat of the sun and its own weight if the pile is quite high. The outer layer of the pile is typically the only area affected by the sun.” McIntyre suggested if either the problem of agglomeration or clumping occurs, send the effected RAS through the grinder for a quick, second pass to bring the RAS back to usable form. He also reminded readers they can use simple additives to prevent clumping. When stockpiling or feeding RAS, time, temperature and moisture can cause agglomeration of the particles into clumps that negatively influence quality control. While using sand in the RAS stockpile has the secondary benefit of shining some plant components by preventing RAS from sticking as it goes through production, it can have a negative influence on QC, depending on the cleanliness of the sand. Clean sand can be costly. Dirty sand can throw a good mix off

Along with fractionating RAP and declumping RAS, producers will want to prep stockpile areas when considering where the recycle material goes. Everyone knows by now to pave beneath stockpile areas. Put berms between stockpiles of differing materials or sizes. Put signs at the edge of stockpile locations to let truck drivers and loader operators know exactly what is in each bay. And then match up those signs to the cold feed bins nearer the plant.

If either the problem of agglomeration or clumping occurs, send the effected RAS through the grinder for a quick, second pass to bring the RAS back to usable form. Argo Industries, Inc., Brookfield, Wis., offers a bin designed specifically for RAS. “We use a vertical front wall and steep-

ly sloped side and end walls along with a cleated belt to improve flow ability,” Paul Vandermolen of Argo said. “What we have found with our users is that when this material is being processed in bins with flatter slope angles, the material tends to pack.” To get material ready, try these steps that Preston McIntyre suggested for basic grinding: Step 1. Single-pass grinding through a small screen hole size Step 2. Double-pass grinding through a larger screen, and then a smaller screen Step 3. Grind, screen and then regrind the overs In the end, the purpose of taking so much time with your recycle material is to get a bonus-worthy mix design. Give quality control your full attention from the moment millings and other recycle material reaches your facility until the final product is in the mix and you’ll know where your recycled product is headed: it’s headed to the bank.

Wrap 100% Recycle into Winter Mix I

n late 2013, Slavic Mokienko, general manager for R.E. Pierson Materials, Bridgeport, N.J., called on RAP Technologies to purchase a used portable recycler. Pierson typically has several loyal customers with ongoing projects when its Dillman drum plant closes for winter maintenance. A recycler would enable Pierson to produce lucrative winter mix without forgoing maintenance or running a 500 ton per hour (TPH) drum to service small-volume winter jobs. Winter mix with 100 percent recycle isn’t a new idea; utility contractors and municipalities have increasingly used Bagela or similar portable recyclers to keep crews working all winter. Slavic soon learned that a recycler “cost too much and didn’t have enough production.”

26 March 2015


The plant at Pierson’s Bridgeport, N.J., location received two trailer loads of equipment to effect the installation of the 100 percent RAP winter mix capability. In these pictures, you can see the Dillman drum plant with its 500-TPH capacity drum already in place. RAP Technologies delivered an Allen Bradley PLC, custom automation and an early-entry combustion zone. You can also see the totes of recycling agent used to soften the aged RAP binder.

RAP Technologies found Slavic’s idea so compelling that the company upgraded its All-RAP pilot plant to produce winter mix and be ready if Slavic called again in 2014. Engineers added the Allen Bradley PLC custom automation with wireless connectivity for the operator’s terminal and a ceramic insulated early entry combustion zone. The result is an all-RAP winter mix plant that can be transported on two trailer loads while it’s sized to serve a winter market at 25 to 500 tons per day. By November 2014, Pierson’s customers started calling to confirm their schedules. Several had utility contracts that would require hot mix daily to pave over street openings. Others had commercial parking lots that would be ready for base to support construction activities. Based on this demand, Slavic believed that “we could supply our customers throughout the winter and also be profitable.” The market justified a three-

month lease between Pierson and RAP Technologies with 1,000 ton per month production minimums. Dec. 30, 2014, Billy Bowling, Pierson’s operations manager, moved the all-RAP plant’s dryer and baghouse trailers to Pierson’s facility and began connecting ductwork and SO electric cables. Bowling placed the plant between the storage silos and Dillman aggregate dryer in order to discharge mix into the main drag conveyor. Being close to the Dillman dryer enables the winter mix plant to use line power provided by a 100HP drum drive motor starter. The wireless connectivity of the operator terminal enables Duke Strang, plant operator, to run the plant from his Dillman control room. This feature wasn’t added just for Strang’s comfort, but also so he could use the truck loadout and billing interface while operating the winter mix plant. He found that running the all-RAP www.theasphaltpro.com 27

plant is easier than his Terex automation, taking only two keystrokes to start the plant in a fully automated startup sequence. The equipment lease between Pierson and RAP Technologies includes a supply of recycling agent. The recycling agent is a local, repurposed, non-toxic, organic material that softens age-hardened RAP binder for the purpose of producing durable, easy-to-work mixes. The product is delivered in 250-gallon IBC totes and added at a rate of 1.25 gallons per ton of mix. This dose restores PG64-22 performance to the RAP binder and balances rutting and fatigue cracking resistance, according to the manufacturer. Totes are kept warm in a heated garage overnight, and then connected to the plant in the morning to pump accurately. Dan Karcher, the quality control manager, routinely fractionates his RAP with an Astec PEP screener into ¼ and 3/8-inch fractions. These fractions give him control over gradation and asphalt cement (AC) content throughout the year. For winter mix, Karcher set up the PEP screen to make slightly different fractions that, when reblended, enable production of both base and surface mixes with just RAP aggregate and recycling agent. Karcher changed the 3/8-inch top deck screen to ¾-inch and will use that fraction to produce both base and surface winter mixes. This is a new concept in 100 percent mixes, but Karcher is well-known for designing quality mixes with high RAP. Air permitting for the all-RAP winter mix plant wasn’t an issue because New Jersey offers a special exemption for temporary portable equipment operated while stationary manufacturing components are repaired or maintained. A registration form was submitted to the New Jersey Department of Environmental Protection prior to the start of work and a second notice will be submitted at the end of the 90-day maintenance period. It was that simple. 28 March 2015

In May 2011, New York City’s first commercial 100 percent recycled asphalt plant opened using RAP Technologies’ All-RAP patented technology. The first season was focused on introducing contractors to the quality of 100 percent recycled mix. That task became much easier in January 2012 when the All-RAP plant stayed open while other producers serving NYC closed for maintenance. As a result of this availability and discount price, many contractors with winter projects purchased 100 percent recycled mix for the first time; their positive experiences kept them coming back during the regular paving season. Demand for 100 percent recycled mix has continued to increase every year, even as conventional plants saw declining sales (see Figure 1). RAP Technologies’ All-RAP technology is designed to be retrofitted on conventional plants as a parallel system enabling producers to switch back and forth between 100 percent RAP and conventional mix on a day to day basis. This is proving to be an attractive option in small or slow markets where operating a conventional plant is not profitable until large projects need that capacity. Portable recyclers, Pierson’s winter mix rental, and the NYC experience suggest that the market is ready for 100 percent recycled mixes. Bob Frank is the founder of RAP Technologies.

or those not already familiar with the soil stabilizer-reclaimer, it can be used for mixing lime, fly ash or cement with existing materials to improve soils and strengthen sub-surfaces in preparation for backfill, antifrost layers and base layers. In the application seen in the focal image here, the new SX-6e/ex soil stabilizer-reclaimer from Roadtec, Inc., Chattanooga, works a section of existing pavement. The machine is used to smooth out and stabilize the lane. The SX-6e/ex sits in the mid-size spot of its family of four different size soil stabilizer-reclaimer machines. The SX-6 cuts up to 20 inches (508 mm) deep and 100 inches (2,540 mm) wide. The machine is equipped with a Tier 4 interim 6-cylinder, 600 hp (447 kW) Cummins® QSX15 diesel engine that is engineered to provide power to the rotor through a direct drum drive. The engine compartment is fully sealed, which means it’s de-

signed to prevent infiltration by dirt or dust from soil binders. With a shipping weight of 68,000 pounds (29,480 kg), the Roadtec SX6e/ex is designed to be balanced evenly for maximum traction. Four cutting speeds and right-hand flush cut allow it to be used for a range of projects including stabilizing, pulverizing, or cold recycling. An air-shift transmission for the cutter speeds means that the operator can shift to different rpms on the cutter drum depending on application need. The variable geometry cutter housing arrangement of the SX-6e/ex is designed to position the cutter in a way that promotes material sizing as well as the flow of the material. Heavy-duty front and rear doors are hydraulically adjustable for additional control of gradation and flow. The Roadtec SX-6e/ex soil stabilizer-reclaimer is ready to perform road rehabilitation, cold recycling, or soil stabilization. www.theasphaltpro.com 33

Submersible Pump Gets Agg-Washing Right From BJM Pumps

O

ne of the largest producers of stone aggregates in the southeastern United States, Midsouth Aggregates, headquartered in Birmingham, Ala., produces aggregates by quarrying naturally occurring rock deposits. Granite and limestone are extracted by carefully controlled blasting, then are crushed and graded to produce stones of different sizes to be used in various applications. The company supplies aggregate products to the Alabama, Georgia, Tennessee and Florida Departments of Transportation, the U.S. Army Corps of Engineers and the Federal Aviation Administration. A Midsouth Aggregates plant in north central Alabama needed to replace a sub-

36 March february 2015 2015

mersible pump that pumped quarry water to a stone washing tower. The plant also wanted to increase the discharge flow of the pump. The existing pump had a 4-inch discharge. The new pumping conditions were 1000 GPM, 50 feet of vertical lift and 500 feet of horizontal run to the water tower. The manufacturer of the existing pump would have to use a pump with an 8-inch discharge to meet the new conditions; BJM could accomplish the job with a 6-inch KZN. At the operation, the aggregate from the bedrock deposits are classified as hard, medium-hard and soft. After it’s harvested, the quarry rock is processed, which involves crushing, screening and cleaning.

Massive stones are sent along a vibrating feeder from the feed bin to a jaw crusher for rough crushing. The smaller rock is then transferred by conveyor to a cone or impact crusher for secondary crushing. The fine crushed stones are transferred to a vibrating screen for separation by size. Stones that meet the specific requirements of the finished product are transferred to a finished products pile. The remaining stones are sent back to be crushed again. Dust suppression equipment is often used as additional environmental protection.

ment, suggested a BJM Pumps submersible built specifically for hard-to-handle rock slurries. Midsouth Aggregates didn’t have any experience with BJM submersibles, so Morrow provided information on the BJM KZN hard metal slurry pump. Specifically, Morrow suggested the BJM KZN220-30 HP high head, hard metal agitator slurry pump. The existing submersible pump in Midsouth Aggregates’ application was a side discharge 90-degree elbow pipe that had a high wear area on the 90-degree turn. BJM’s vertically positioned top discharge KZN promotes optimum wear resistance along the discharge path as well as use of the fluid being pumped for natural cooling of the pump’s internal motor functions. BJM’s

vertical design also allows for the sump to be pumped down to within inches of the bottom. The vertical discharge and the 22.75-inch diameter of the KZN220 create a space-saving footprint, allowing installation in the tightest of manholes. Midsouth Aggregates’ Alexander City Quarry Plant Manager Shane Horton mentioned that the BJM KZN220 has been in operation for more than three years. “We start the pump when the day begins and shut it down when we leave at the end of the day,” he said. The pump’s ability to pick up siltladen water from a groundwater pond and pump it to the rock screen washing tower has provided trouble-free operation.”

KZN220: Just the Facts

• Wear Resistance—All wetted parts are constructed of abrasive resistant 28 percent chrome iron (600 Brinell, 71 Rockwell C). In addition, a replaceable hardened wear plate is located on the suction side, where erosion would cause a loss of pump performance. • Solids Handling Capability—An integral agitator fluidizes settled solids into a slurry, making them easier to pump with less chance of clogging. The semiopen impeller handles abrasive solid concentrations as high as 70 percent by weight. • Double silicon carbide mechanical seals in a separate oil filled seal chamber • Heavy duty lip seal for additional protection for the mechanical seals • Stainless steel shaft and shaft sleeve • Pump volutes cast from hardened ductile iron (300 Brinell) • Semi-open impeller made of 28 percent chrome • Vertical top discharge

T

he material handlers at the plant are instrumental to quality production. These employees include your plant operator, loader operator and ground personnel. They have a whole lot of say regarding the quality of mix your plant produces. You need to have trust in your loader operator. “You can’t make quality mix without a good loader operator,” Ted Brommenshenkel said. He’s the plant maintenance supervisor for Brannan Sand & Gravel Co., Denver. “A good loader hand will know to remove wet material on the shell of the pile and not feed it into the plant. Inconsistent material with varying moisture contents fed into the bins will greatly influence plant operations.” To properly handle materials in plant operations, all personnel must follow proper protocols, such as performing a visual inspection of materials. The plant operator will perform a visual inspection of the plant as well. While performing a visual inspection of the plant, he will want to open the pump valves to get the oil circulating. Completing this step in the early stages of a cold start will help homogenize the binder and assist with getting a consistent asphalt content during initial production. The exhaust fan on the baghouse should be kicked on, followed by purging the burner blower. Next, the operator should turn on the drum, slat conveyor, scale belts and weigh feeders. Remember that most equipment performs best when it is warmed up prior to production. As the operator turns on these components, he should be aware of the gauge 38 March 2015

The type and placement of flights in the drum, and how the material is veiled through the hot gases, will have an effect on both the drying temperature and the baghouse temperature. Positioning of the flights is another area filled with options, which are discussed further online.

readings to assure everything is in working order. Check the amperage on the slat. Assure a zero on the scale belts. Make sure the settings are correct. Make a checklist and put a checkmark next to each item as you visually inspect it. The operator then will start the fire on the burner and get the baghouse warmed up. Temperatures going into the baghouse should not exceed 300⁰F during the warm up process and should be monitored. While the plant components are warming, a plant operator or ground person should walk around the plant again and visually assess the equipment while it’s running. Next to vision, one of the best senses this person has is hearing. Unfamiliar sounds, such as abnormal screeches, bangs or squeaks, are signs of trouble, and should be investigated. Following this step will allow the plant operator to inspect the belts for wear, find a squeaky bearing that may need some grease, confirm safety items are in place, and look for potential items that need addressed. When the operator feels that the plant is ready to go, he will enter the target tons

per hour and mix design into the computer, start the aggregate feed from the bins and the AC pump. Timing is critical during this stage; good timing can reduce plant waste. The operator has a host of components to monitor at this point: • Baghouse temperatures • Bin sequencing • Mineral filler feeds • Aggregate temperatures vs. RAP feed • Injection timing • Drag slat temp and amp readings • Heating circuit readings • Truck loadout Following basic guidelines will help assure a quality asphalt pavement is produced. Having the proper components in place is critical; having good employees who know their plant and their roles at the helm is even moreso.

Mix in Slag By AsphaltPro Staff

A

lthough we’ve discussed the use of slag before, AsphaltPro revisits the concept for the annual recycling issue. As a recycled product, slag is another tool in the asphalt industry’s belt for making sustainable pavements. With this primer, we’d like to give a clearer and basic understanding to those who might be interested in the incorporation of slag with asphalt mix design. Keep in mind, once the slag is created and shipped to the producer for use in a mix, it is stockpiled like any other aggregate and used like any other aggregate, according to sources.

Slag Process

Start with the definition. Basically, slag is a product of the steel-making process. Alan Bowman of Phoenix Services, LLC, shared

that slag was once scorned as a useless byproduct. “It is now accepted and often preferred as a valuable material with many and varied uses in a giant construction industry. It might be best to describe slag simply as ‘man-made rock.’ Its formation begins when iron ore, coke and a flux— either limestone or dolomite—are melted together in huge furnaces. When the metallurgical melting process is completed, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and the coke ash to form a non-metallic product.” The nonmetallic product? Slag. “During the period of cooling and hardening from its molten state, slag can be treated to form any of several specific types, which can in turn be crushed or

screened to isolate diverse grades and sizes. The primary use of slag is as an aggregate but research and experimentation have turned up a number of additional applications and promise to still find more.” Bowman reminded readers of the 4 types of slag: • air-cooled slag • expanded slag • granulated slag • steel-furnace slag “In asphalt paving, as in so many other applications, slag again demonstrates its extreme versatility. It has been used for parking lots of giant shopping centers, to build handsome and durable driveways for residences of distinction and to surface the famous racetracks of Indianapolis and Daytona Beach.”

Slag Specs

Keep in mind, racetracks demand strength, stability and, above all, skid-resistance. “Whether in plant mixes, surface seal or slurry applications, the qualities that are required in turnpike surfacing are also found desirable on local projects. Friction and pavement stability are the top performance characteristics.” Bowman stated that “no aggregate” can compare to the performance of steel slag as an aggregate in asphalt mixes. “Steel slag can provide a renewable friction surface giving the pavement a long life and offers additional safety to the motoring public. It resists rutting and shoving to provide a smooth ride for the driving public. This resists hydro-planing in wet conditions.”

miles. Sometimes more. It depends on customer need. States where slag is produced have specifications for the use of slag aggregate. All of our material (BFS), (BOF) and EAF are all crushed and screened into stockpiles. Many times samples are taken in 40 to 50-pound totes or buckets as needed for mix designs.” The number of states embracing the use of slag in asphalt mix design depends

on two factors: availability and state DOT requirements. “Some customers or state engineers have a bias against use of recycled or manmade products,” Bowman said. “Some have a lack of understanding of high performance mixtures. These are issues we as an industry try to overcome. Slag mixtures are recognized as a very good performing mixture where available.”

The number of states embracing the use of slag in asphalt mix design depends on two factors: availability and state DOT requirements. As for mix design, Bowman shared that “steel and blast furnace slag is often used as 100 percent of total aggregate in the mixture. The mixture depends on the application and cost. High performance mixtures cost more than a lesser performing mixtures.” “Slag aggregates typically are made to same specifications as natural aggregates,” Bowman said. “Phoenix Services LLC provides responsive world-class service to steel producers around the globe. Core services include slag handling utilizing slag pot carriers or the traditional slag pit digging with front-end loaders; the recovery and sizing of metal to our customer’s specification; and processing slag for use by our steel mill customer or marketing processed slag material for aggregate use. We have established regional facilities to process slag and products from steel mills. Incoming materials are processed, crushed and screened to size, to maximize the recovery of metallic. Residual materials are then marketed as aggregate products.” As with other aggregates, Bowman shared that slag also has a short transportation region. “To be competitive we have to be close to the source, often within 45 www.theasphaltpro.com 41

Innovate from the Base for Optimal Performance

I

nnovation and performance optimization lead the topics of discussion at this year’s World of Asphalt Show & Conference and AGG1 Aggregates Academy & Expo at the Baltimore Convention Center in Baltimore, Md., March 17 through 19. The asphalt industry overall has grown accustomed to these two facets of road building—asphalt and aggregates—to co-locate their top education and exposition events each year. For 2015, the National Stone, Sand & Gravel Association (NSSGA) invites attendees to “Optimize Your Performance Potential,” while the National Asphalt Pavement Association (NAPA) welcomes attendees to “The Base of Innovation.” In past years, multiple state association meetings and safety programs ran concurrently with the People, Plants and Paving Training Sessions, and AGG1 Academy. This year is a little less confusing while still offering useful education for your employees and your upper echelon management. For example, one conference that begins a day prior to World of Asphalt is the Beyond Compliance: Achieving EH&S Excellence. This Monday through Tuesday conference is tailored to environmental, health and safety officers at asphalt plants and

paving sites. The 11 sessions within the conference are designed to give attendees the latest information on innovations to build a world-class EH&S culture. Visit www.worldofasphalt.com/ Education/General/BeyondCompliance/ for the noon-to-noon schedule and registration information. Also beginning Monday and extending to include Tuesday afternoon, the American Road and Transportation Builders Association’s Safety Seminar “Safety in the Work Zone” offers two educational tracks. Visit www.worldofasphalt.com/Education/General/SafetyInTheWorkZone/ for course descriptions and registration information. Both AGG1 Academy and WOA’s People, Plants and Paving Training Program begin Tuesday, March 17 and run through Thursday, March 19. There’s plenty of information starting on page 46 about the sessions. The highlight of such a gathering for many contractors is the trade show floor, of course. Who can resist taking a selfie next to a KM International T2 asphalt recycler or funky MA 10 sealcoat melting kettle? (booth 1658) Caption that: “He’s so hot he melted that crack filler material.”

brook, Conn., won’t be exhibiting, but did launch its new XP-KZN series of submersible slurry pumps at the Underground Technology Conference & Exhibition in Houston back in January. Neal Manufacturing of Anniston, Ala., also chose another venue to showcase its sealcoating machine due to a scheduling conflict during WOA time. Now let’s take a look at a few of the companies that will be at the show and that shared information with AsphaltPro readers. When you stop in to check out the new items and info, let them know you saw them in AsphaltPro magazine.

›› ALBARRIE WOA-1821

Get information on high efficiency filter bag cleaning from Albarrie Environmental Services when you stop by booth 1821. Atlas Copco’s new Dynapac F1200CS paver has a laying capacity of 330 tons per hour. Check it out in booth 2514 during the WOA show.

Or maybe you want to stare into the jaws of an Eagle crusher (booth 1542) or see the impact of a KPI-JCI/Astec Mobile Screens crusher (booth 1634). The testing companies will have their sieves all shiny at booths 2132 (Gilson Company Inc.) and 3529 (Instrotek Inc.) and 1751 (Troxler Electronic Labs) and 1552 (Pine Instrument Co.), etc. Are you used to seeing the same old folks with the same old equipment at these shows each year? Well, you’ll be happy to hear that “The Base of Innovation” brings out the creativity in the OEMs and service-providers in our industry this year. Now, if you ask a representative what’s innovative about his or her product, its very existence will be the fabulous aspect about it, right? But the folks who spoke with us at AsphaltPro shared technology tidbits beyond “our stuff is great.” For example, a spokesperson for TransTech Systems of Schenectady, N.Y., explained that the non-nuclear density gauges the company offers and will have on display in booth 1548 use electromagnetic technology. Without giving away the “secret sauce,” that’s what makes the gauges work, making them non-nuclear and offering the advantages over the nuclear alternative. The team at BOMAG Americas, Inc., has optimized the vibratory oscillation within its roller drums to create the TanGO. You can check this out on the company’s new BW 161 ADO-4 tandem roller in booth 1130. It’s “tangential oscillation,” thus the name TanGO, that directs forces horizontally to give that special compaction touch near buildings or on bridges. Bob Frank of RAP Technologies, LLC, Linwood, N.J., shared that the innovation he brings to the show is that of running a fully recycled hot mix. “High capacity production of 100 percent recycle mixes using conventional plant components,” is possible. A number of companies have innovations coming up, but they won’t be exhibiting during WOA/AGG1 for a variety of reasons. For example, CWMF Corporation of Waite Park, Minn., will introduce a 100 percent RAP plant later in the year; you can watch our product gallery pages for that. Phoenix Services LLC of Kennett Square, Pa., isn’t exhibiting this year while the company finalizes details at its newly acquired sites. BJM Pumps of Old Say48 March 2015

Learn Something New Every Day

B

oth AGG1 Academy and WOA’s People, Plants and Paving Training Program have succumbed to the trap of giving original equipment manufacturers (OEMs) the floor when it comes to presenting in 2015. But is that a bad thing? OEMs employ engineers and sales professionals who understand the technical and structural problems that departments of transportation (DOTs), end users and asphalt professionals face. From consultants to producers to engineers to OEM representatives to asphalt producers to long-time affiliates in the industry, the experts have stepped up to the plate to bring real-time information to the attendees who make it a priority to take notes in the seminars and workshops during their time in Baltimore. As one of those presenters, Editor Sandy Lender invites you to take the time to turn off your cell phone and fully engage in one or more of these sessions per day. Take advantage of this gathering of knowledge to soak up new advice, new ideas, new information, new methods, new ways to grow your business from the base of innovation on up. A spokesperson for Atlas Copco said, “There are a lot of good seminars at WOA and it’s such a great opportunity for attendees to learn a lot under one roof. However, there are two [sessions] that I recommend as they can have a significant impact on businesses. The first is ‘Compaction 101: Getting the Roller Pattern Right and Staying Consistent.’ Compaction is such a critical part of road construction that directly affects the integrity and lifespan of the road. It can essentially make or break a project and if it’s breaking a project it’s doing some damage to your bottom line, too. That’s why it’s important to know some of the best practices when it comes to this. We also recommend ‘ What’s the Latest on In-

58 March 2015

telligent Compaction?’ Intelligent compaction is such a great tool for contractors that can really save them time, hassle and money, yet it’s still underused. This is a great opportunity for contractors learn more about the systems that are out there and how they can impact their businesses.” The team at BOMAG Americas also recommended these two seminars. “These two seminars will help contractors learn the latest in compaction technology and applying the best rolling patterns to achieve desired compaction results,” they shared. You’ll find these sessions listed as W35 and W14, respectively. In fact, session W14 is popular with several folks who recommend getting in the audience to hear the panel discuss the latest technologies in intelligent compaction (IC). Bruce Monical of Wirtgen America wanted to bring attention to three courses, including W14. If your interests are in milling, paving or compaction, be sure you look into #T33, #W12 and #W14. Those are, respectively, Best Practices for Milling and Profiling with Tom Chastain on Tuesday, March 17, at 2 p.m.; What it Takes to Make Cold Central Plant Recycling Work with Brian Diefendorfer of Virginia DOT and Don Matthews of Pavement Recycling Systems, Inc., on Wednesday, March 18, at 7:30 a.m.; and What’s the Latest on Intelligent Compaction with Tim Kowalski and others on Wednesday, March 18, also at 7:30 a.m. The team at TransTech Systems, Inc., Schenectady, N.Y., believes the more you know, the better informed you are, so they recommend a number of sessions. #T13-Laydown Best Practices. “This is key to obtaining your targets.” #T24-A Practical Approach to Managing Density. “This one is directly related

By AsphaltPro Staff

to the area of expertise TransTech has with non-nuclear density gauges.” #W14-What’s the Latest on Intelligent Compaction. “Is real-time density measurement in the near future?” #W25-Best Practices for Residential and Commercial Paving: “We are your go-to company for best practices.” #W34-Best Practices for Construction of Longitudinal Joints: “Our compaction solution to longitudinal joints is the Notched Wedge Joint Maker system.” #W35-Compaction 101: “Our products help achieve the compaction required.” #T31-“Support AsphaltPro!” Paving courses aren’t the only ones on the menu. Eagle Crusher suggested attendees check into “Understanding Materials and Plant Operations to Use High RAP Content, because it will help educate how RAP production will decrease costs and increase profitability.” Remember that the courses are separated into tracks or areas of interest for the industry. The program tracks are People, Plants, Paving, Safety and Pavement Preservation. While those are self-explanatory, note that the “people” section encompasses everything from leadership to marketing your business. It focuses on skills you can acquire or learn more about to manage your personnel or yourself to maximum performance levels. This is where AsphaltPro is proud to mention our editor, Sandy Lender, will present a way to promote your individual business, as well as the asphalt industry overall, through various online platforms. Her focus will be on how to market yourself online to grow your business without falling for the time traps that many social media sites lure you into. In other words, Lender has tips and advice to make your online business growth more efficient to result in more tons.

Paving and Pavement Maintenance Essentials By AsphaltPro Staff 64 March 2015

A

s we gear up for the start of the spring paving season, AsphaltPro begins a new way to examine the equipment, products and services available in the marketplace to asphalt professionals. Of course we will still focus on the items relevant to an asphalt business, but we have a new approach to make the focus more useful to you, the reader and end user. Notice this month that all equipment and services listed in the Product Gallery relate to the “paving” side of the industry. From the information we receive and solicit from OWMs and consultants, we’ve selected just the bits that pertain to laying and compacting a gorgeous asphalt mat, or maintaining and preserving any pavement surface, or profiling and testing the road for perfect quality assurance. When you see the Paving and Pavement Maintenance Equipment headline for our Product Gallery, you’ll know you have the latest and greatest in the paving/preservation/testing side of the asphalt game.


LEFT: The autotracking package serves as a sort of tether between the paver and MTV, allowing the MTV operator to keep his machine traveling at the same speed as the paver. This keeps the MTV at a constant distance from the paver as the two move down the lane, delivering material to the hopper from a constant height. ABOVE: The two light towers on the MTV alert the operator when the paver is going to change speed.

cate when the paver speed is going to increase, decrease, or when it is maintaining the appropriate distance between the machines. Control switches for the autotracking package are also located on the Shuttle Buggy’s C1 conveyor and operator console. These controls allow the Shuttle Buggy operator to select between automation or manual modes. In either mode, the light towers provide continuous aid to the operator in judging the distance between the paver and MTV. For more information, contact Joanna Peddicord at (423) 265-0600 or jpeddicord@roadtec.com and look for the in-depth Here’s How it Works equipment feature in the April/May issue of AsphaltPro.

TREAT YOUR DIESEL SYSTEM

ROADTEC AUTOTRACKING MATCHES COMPONENTS’ SPEEDS

The autotracking package for the Roadtec Shuttle Buggy® material transfer vehicle (MTV) automates the machine so that it can operate at a continuous speed with a paver, according to the manufacturer. This new option enables the paver to set the speed for the two. Currently, MTV operators have to monitor and adjust equipment speed to keep the distance from the paver constant; with the autotracking package, the speed of the Shuttle Buggy is automatically adjusted up or down to maintain a set distance from the paver. Pendant controls give the paver operator the ability to enable or disable the autotracking and swing the Shuttle Buggy conveyor that feeds the paver. Two light towers on the Shuttle Buggy indi-

APP OFFERS MORE THAN A CATALOG

At first blush, the new app from Atlas Copco, Commerce City, Colo., looks like an electronic catalog of products you can access in the field. Upon further investigation, it proves to be more. The Atlas Copco Construction Technique Business Area has launched the app for use with Apple and Android devices, tablets and smart phones to keep the end user up-to-date on the latest news out of the company, including product releases, but also to provide training on the use of equipment, emergency maintenance, or other needs. A spokesperson for the company explained: “The Construction App helps a contractor with equipment planning by providing all the information needed to make sound equipment purchases or renting. For example, if a paving contractor wants to learn more about a Dynapac paver or asphalt roller that he or she saw at a rental yard, they could pull up the model on the app and download its product information to see if it will meet the project’s requirements. The app also has filter settings to focus on equipment that fits a contractor's preferences or requirements. For example, a contractor can use the filter to focus on different types of asphalt rollers, drum types, steering types, operating mass, module mass and compaction width. On the job site, a contractor can also use the app to pull up Atlas Copco’s contact information or submit a service request for a piece of equipment. This alleviates the hassle of searching for a contact online and puts the contractor in direct communication with Atlas Copco. A contractor can also use the app to download training videos to help teach a new operator how to run the equipment.” For more information, contact Atlas Copco at (800) 732-6762 or visit www.atlascopco.us.

The lightweight hood of the Volvo DD25B tilts forward with the aid of two gas struts providing wide access to the engine and hydraulic components of the compactor at ground level.

ROLLER MEETS REGS WITHOUT AFTERTREATMENT

The Volvo DD25B double drum compactor is powered by a three-cylinder engine that meets Tier 4 Final emissions regulations without an after-treatment system. The Tier 4 Final engine is designed to deliver high productivity and low fuel consumption with a 7 percent decrease in fuel from the previous engine without the added cost of servicing the SCR or DPF. In addition, the Volvo DD25B is built with minimal maintenance requirements. The front and rear drum wipers are made of urethane, to increase effectiveness and service life while the eccentric bearings are lubricated for life. Auto-start vibration engages automatically when the FSR lever is moved out of neutral and disengages when the lever is in the Stop position to eliminate accidental damage to the mat.

here's how it works

Step 1 Fine material particles and water vapor are created inside the milling drum assembly during the milling process.

Step 2 The Vacuum Cutting System applies negative pressure to suck fine particles from the cutter housing into the milling machine’s short conveyor channel.

Step 4

Step 3 A suction hood located above the conveyor channel pulls the particles into two hoses.

The hoses transport the extracted particles directly to the long conveyor of the front loading system.

Hydraulically-driven centrifugal fan

Step 5 A yellow plastic “bell” captures oversized particles from the air stream.

Wirtgen’s Vacuum Cutting System

W

irtgen GmbH introduced its Vacuum Cutting System (VCS) for use in front-loading road milling machines to suppress airborne material particles, which are produced by the milling process. All Wirtgen’s larger cold mills can be fitted with the CVS to extract fine material particles at the cutter drum. By creating a negative pressure in the drum housing, the mix of air and water vapor Is evacuated and then fed back into the flow of the milled material transported on the conveyor via a hose system. Here’s how it works. First, fine material particles and water vapor are created inside the milling drum assembly during the milling process. VCS be-

gins by applying negative pressure to suck these fine particles into the milling machine’s short conveyor channel. Additional sealing of the milling drum assembly supports this process. A suction hood located above the conveyor channel sucks the particles into two hoses, which transport the extracted material particles directly to the long conveyor of the loading system. Again, the process is supported by sealings in the short conveyor channel and at the suction hood. A hydraulically driven centrifugal fan installed on the conveyor makes sure the extracted material is fed into the long conveyor channel. Negative pressure is creat-

ed in the milling drum assembly at the same time. Additional injection of water at this point binds most of the particles. The water-bound particles are finally returned into the stream of material and are, for the most part, fed into the truck together with the milled material during the loading process. Better air quality and visibility in the working environment of the milling machine operator and ground crew members improves crew comfort and productivity, while reducing wear and tear on the machine.
