What’s New in Asphalt Production?
AsphaltPro sets the standard for equipment and service information by focusing on what’s new in the industry. There are companies in the asphalt industry with R&D departments that have crafted remarkable components for aggregate and asphalt production that stand the test of time. Over the years, those components require mere tweaking here and there to bring them up to date with some new code or concept from EPA. As those modifications are introduced, AsphaltPro is honored to share the information with readers, keeping everyone abreast of changes in our industry.
Take the 12-foot Whirlwind air classifier from Sturtevant that was installed at Rockydale Quarries in Roanoke, Virginia, in 1961. The classifier is still making agricultural lime and minus ¼-inch sand for asphalt production after Sturtevant supplied parts to Rockydale to do some refurbishing. Writer Carl Emigh shares the whole story here:
The machine was refurbished by Rockydale with parts supplied by Sturtevant in 2015 after more than 53 years of continuous operation. The refurbishing cost was 40 percent of the cost of a completely new machine.
“We worked closely with Sturtevant throughout the refurbishing process,” Rockydale Vice President of Operations Gary Hubbard said. “They tailored everything to our needs. I just gave them the requirements we needed to work within, and they handled it with us from there.
“Sturtevant was able to refurbish the air classifier since the basic design hadn’t changed much,” Hubbard continued. “Essential parts such as the fans, distributors and cones were original. And all Whirlwind parts are readily replaceable, which eased the refurbishing process. Most of the original rotating parts did not need to be replaced, including the heavy-duty drive mechanism.
“Two key Sturtevant people on the project were Senior Project Manager for Air Classifiers Joe Muscolino and Parts Manager Rick Fortini. Both have been with Sturtevant for more than 30 years. They worked in concert with our Luis Lopez to make it all go like clockwork.
“Rockydale is a small, family owned company,” Hubbard continued. “So is Sturtevant. That’s one of the reasons we like working with them. They’ll go the extra mile to accommodate your needs and give you the attention you won’t always find with larger companies. We got a like-new 12-foot Whirlwind classifier brought back to its original condition in minimum time and at a good, low cost.”
Rockydale also uses a 16-foot Sturtevant Whirlwind air classifier to produce aglime and minus 5 mesh sand for concrete production. That machine was installed in 1985 and replaced in 2007 by another 16-foot Whirlwind when it was damaged by fire.
“Our crushing and screening system uses a 42-48 jaw crusher, four cone crushers and seven screens to produce rip-rap, gabion, 3-inch by 1-inch, 57s, 8s, and 10s,” Hubbard said. “We use the Sturtevant air classifiers exclusively to produce agricultural lime and the concrete and asphalt products. One circuit produces 70 TPH; the other produces 50 TPH. The classifiers have no trouble keeping up with that production rate.
“The feed material is dolomitic limestone with 4 percent silica and no caustic chemicals, which keeps wear to a minimum,” Hubbard said. “Acceptable moisture content averages 2 to 5 percent. Anything higher slows production. The two air classifiers are fed a fine graded material and produce a very high quality sand. To aid in moisture control, the 12-foot is enclosed and the 16-foot has a covered feed conveyor.”
Hubbard says the Sturtevant Whirlwinds are tough, efficient, and simple to operate and maintain. “We do a weekly inspection: just open up the door to see how the blades, tips and distributor plate look. There’s virtually never a problem so we close up and keep on producing. Once the selector blades are dialed in to match the gradation you want, the upkeep on the unit is very simple. Nevertheless, diligence in maintenance and service are still crucial. Ray St. Clair, who has been with Rockydale for 39 years, has been a major contributor to the ‘care and handling’ of our air classifiers. We keep all our equipment in good repair, and it pays off in production efficiency and long service life at minimum cost. Our Sturtevant Whirlwinds are the prime example.”
Rockydale Quarries Corporation has operated in the Roanoke Valley since 1932 and now has eight plant locations across the state of Virginia, providing a wide variety of aggregates, lime, and topsoil for construction, agricultural, and residential markets.
We’re taking a wide look at plant and quarry equipment this month. Many OEMs with R&D departments revamp complete systems, software, iron and parts to make completely new products to address different needs in the aggregate and asphalt production realm. It takes guts to put in the time, money and manpower to fabricate a new WMA injection system, a new material delivery system atop the silos, a new burner, and the list goes on. When a manufacturer launches a new product or custom-builds a component, again AsphaltPro is proud to share that news with readers, keeping everyone up to date with the advancements in our industry.
This product gallery focuses specifically on the branch of our industry that influences your bottom line when it comes to the production of aggregates, asphalts and mixes. This month, we asked OEMs and others in the industry to provide information related to mix production for equipment and services they launched this year. You’ve seen the old stuff. In alphabetical order, let’s take a look at what’s new in the asphalt production market place to enhance your bottom line.

When heavy highway and civil contractor Evans & Associates Enterprises Inc., Ponca City, Oklahoma, learned the construction software it had relied on daily since the mid-1990s would no longer be supported, the company knew the replacement challenge also presented an opportunity to improve its operations.
“We wanted the functionality to bring a lot of the consistency into our operations and into our back offices,” Lee Evans said. He’s the president and CEO of Evans & Associates. “We wanted to streamline a lot of the processes that were not tied together well before—from our operations in the field to our accounting to our compliance. When we looked at Spectrum, we knew we could do just that.”
Evans & Associates has steadily grown over the years. The company began in 1960 when Evans’ father and a partner purchased a single asphalt operation in Ponca City. Fifty-six years later, the company has grown and diversified to 17 independent business units throughout Oklahoma, employing more than 300 people. While the Company continues to provide hot mix asphalt and construction services to its customers in North Central Oklahoma, the company also manufactures ready mixed concrete, quarries sand and aggregates, installs underground utilities, and markets Type “C” fly ash. With operations located in Ponca City, Red Rock, Alva, Enid, Perry, Bartlesville, Miami, Grove, Skiatook, Altus, Lawton, Ft. Sill, Snyder and Oklahoma City, Evans & Associates continues the proud tradition of its founder with a reputation for quality and integrity.
“Evans & Associates has shown over the years that it is committed to smart growth and building strong relationships with its clients and we’re very happy to welcome them as a client of ours,” Dexter + Chaney President and CEO Norbert Orth said. “We look forward to helping Evans & Associates streamline their operations and take their business to the next level.”
Evans said when his company learned that its Maxwell Systems’ StreetSmarts software would no longer be supported, it was important to keep their operations smoothly running during a software transition. In demos with Dexter + Chaney and its business partner, OnPoint Construction Software, Evans and his team were able to see how Spectrum worked with live data and were especially impressed by the software’s navigation and its Document Imaging and Plan Room functionality.
“Spectrum’s Plan Room functionality was huge for us,” Evans said. “We have a big heavy civil group that does a lot of work on military bases and after looking at the functionality in Plan Room, we feel it will be quite helpful for that group in providing real-time collaboration with the multiple subcontractors on those types of projects.”
Evans added that Dexter + Chaney sales engineers listened to, and put the needs of Evans & Associates first during demos, including working with the company to fit the software to meet those needs. “It was a pretty unanimous decision for everyone on our team; once we looked at all of our options on the market, Dexter + Chaney’s Spectrum product stood out.”
One of the most impressive features for Evans though, was not necessarily software related.
“The thing that really stood out to me was Dexter + Chaney’s approach to customer service,” Evans said. “It’s hands-on. You’re talking to a person rather than a help desk where you send an email and wait for a reply. We’re old school and like talking to people. When we do have an issue or something we want to talk through, we like the fact that we can pick up the phone and get it resolved quickly.”

From Eagle Crusher Company
UltraTraxx™, Eagle Crusher Company’s latest product innovation, came on the market May 2016. This portable impactor track unit, equipped with the company’s UltraMax® UM-15 impactor, is designed for ultra-mobile crushing on the job site.
To keep producers up and crushing, UltraTraxx has fuel capacity for more than 10 hours of operation. The UM-15 impactor provides the industry’s only lifetime rotor warranty (North America only) on its solid-steel, three-bar, sculptured rotor for minimum downtown. The load-sensing hydraulics improve fuel efficiency and reduce component wear for lower operating costs and minimum downtime as well, according to the manufacturer.
Helping producers achieve their highest production rates, the UltraTraxx all-hydraulic, hydrostatic-drive system allows independent operation of the conveyors, feeders and impactor. Material processing efficiency is maximized by the UltraTraxx smart feeder drive system by monitoring engine load for more efficient production and product consistency.
Further enhancing production rates, the UltraTraxx dual-motor, under-crusher pan feeder, with discharge clearance of more than 20 inches, provides greater material flow and maximizes uptime by virtually eliminating clogging, according to the manufacturer.
UltraTraxx high torque drives ensure superior tramming and gradability, enabling the unit to track while crushing, so operators can continue stockpiling and also maximize production. Uptime is maximized with the UltraTraxx on board hydraulic cooling fan that reverses to minimize heat exchanger clogs.
Thoughtfully designed maintenance features also help provide maximum uptime and include the easily removable discharge conveyor for quick access to the under-crusher area for inspection, maintenance, and cleaning. With the discharge conveyor removed, operators can also quickly inspect and maintain the conveyor. The discharge conveyor is fitted with one of the plant’s easy-access grease banks for lubricating the head and tail pulley bearings, and the conveyor folds for transport or to remain out of the way for more compact storage when not in use.
To help ensure the highest quality spec product, UltraTraxx is equipped with a permanent, cross-belt magnet to remove steel contaminants from crushed material. The magnet is reversible to allow steel to discharge from either side of the unit, and the magnet does not need to be removed for transport.
The UltraTraxx heavy-duty hopper is sized for feeding with a loader or excavator, and the unit has a discharge conveyor height of 12 feet 5 inches for feeding directly into an optional screener.
The UltraTraxx includes a wireless remote control to operate and monitor plant functions including filter status, hydraulic oil temperature, engine load and charge pump pressure. The control can be tethered to the unit for operation if the remote battery loses its charge. Typically, a charge will last 8 to 10 hours, or operators may change the battery when filling the fuel tank. Remote monitoring of crusher production performance, engine loading, temperature, and location is also available. These may be monitored via wireless service to a smart phone or computer.

Heatec says that managers of asphalt facilities in the United States and Canada are showing a remarkable response to the Recon™ monitor system that the company introduced in late 2015. Recon units are now in operation at 23 facilities and being installed at 9 others. Heatec is working through a significant backlog of orders for additional units at press time.
The Recon system enables plant personnel to remotely monitor the live status of asphalt heaters and asphalt storage tanks at their HMA plants. Operators use this information to avoid unwanted shutdowns due to heating problems. And they keep close watch on asphalt use and inventories to better plan tank refills.
The Recon monitor shows heater alarm status, hot oil temperatures, asphalt tank temperatures, tank liquid levels and tank mixer on-off state. Operators can use a smartphone, tablet or PC to access the system.
Chris Cook, Plant Superintendent at King Asphalt, Pacolet, South Carolina, says he really likes the remote access that his Recon system provides. He uses his iPhone to keep close watch on tank levels and temperatures at their facility. And he looks forward to finding ways to use the historical data that the system records.

From Systems Equipment
SYSTEMS Equipment has announced the release of the 1292 Material Temperature Capture at Time of Load, the newest companion product to the company’s Windows-based loadout system, the WIN-LC3000. Product conception was spurred by feedback from both producers and end-users in the asphalt industry with a common objective—to have an efficient way of measuring and documenting the temperature quality of hot mix being used for any given job.
The 1292 assembly consists of a PLC and two modules to be mounted in the control center (with an optional enclosure), as well as a probe and housing assembly that is mounted to each loadout silo (or drum, if used with the blend system).
Asphalt plants employing this technology have the unique position of being able to measure and document asphalt temperatures at time of load, as well as adjust temperatures with better precision for ongoing production based on feedback from pavers applying the product. This quality assurance discipline provides accountability throughout the asphalt “chain” for any given job. Some state- and federally-funded projects also require this temperature measurement to ensure that the asphalt mix meets code-specific requirements.
The 1292 includes a single infrared probe protected by an enclosure measuring approximately 4.5 inches high by 3 inches wide by 3 inches deep. One probe per silo is required. When used in tandem with the loadout system, the active end of the probe is mounted to the loadout silo frame and directed toward the truck bed. A small air valve incorporated into the enclosure prevents debris from attaching itself to the end of the probe and skewing the reading. As loading proceeds, the probe measures the temperature of the newly loaded asphalt mix. The temperature reading is both stored in the loadout database and printed on the driver’s loadout ticket.
The 1292 assembly can also work cooperatively with the blend system, capturing material temperature as the asphalt mix exits the drum. Due to the thick metal housing on traditional temperature measurement units, getting an accurate reading takes time as the heat must work its way through the housing and to the probe. “With the 1292 assembly, the reading is almost instantaneous,” Fred Axmear, software engineer at SYSTEMS Equipment Corporation, said. “This is particularly helpful with small batches, and also improves reaction time when temperatures need to be adjusted because feedback is both quick and accurate.”
He added, “By installing the 1292, operators now have a much greater level of control over the quality of their hot mix. Having the ability to document mix temperatures at time of load also gives them an added level of assurance and documentation for jobs with higher requirement levels, such as federal highway projects. Their bases are covered.”

Updated from Systems Equipment
The Total System Control, launched by SYSTEMS Equipment Corporation in early 2014, is among the most evolutionary products in SYSTEMS’ line of asphalt plant automation, boasting frequent updates and features designed to make life easier for plant operators. Offering touch-screen control of all motors and/or silos, the TSC makes “total control” possible from one to two monitors in a single station within the control room.
“Gone are the days of hard-wired panels with gauges and push-button controls,” Mitch Duncklee, software engineer and developer for SYSTEMS Equipment, said. “Work spaces are now clutter-free and highly efficient.”
Duncklee added that SYSTEMS’ TSC is not rigid when it comes to making plant changes. It is customer programmable because it is “English-language driven,” Duncklee said. “Those who are not versed in complex PLC programing jargon can still understand the software.” To add, move or modify a button can be done by in-house technicians. No Internet connection is typically required.
The TSC lists many features, including recent updates that have made it more intuitive, easier to program for first-time users, and that reduce, if not eliminate, the need for costly service trips for simple changes. Among most recent user-friendly enhancements, the TSC makes:
- adding a new operator or changing an existing one even simpler.
- maneuvering menus easier by making options more visually obvious and simple to find.
- customization possible with “run mode” adjustments for multiple operators.
- reconfiguration of motors or silos simple, as plant technicians can easily add, delete or relocate displayed ‘buttons’ to match plant changes.
“The TSC has made modifying something at the plant as easy as changing a mix formula,” Duncklee said. “The only expense is if more hardware needs to be added.”
New “operators” on the TSC include handling of valves (or flop gates) and limits, multiple interlocked inputs for alarms or indicators, and a tank operator that monitors and controls the functions of each tank.
“Think of programming the flop gate logic for the top of the silos in plain English, without running cables between the limits, in the comfort of the control center,” Duncklee said. “It is easy to set up a combination of existing inputs to fire an output or sound an alarm, all without touching PLC ladder code.”
Rick Moulton of Construction Resources Management compares SYSTEMS’ TSC to a “glass cockpit,” referring to the replacement of dials, gauges and buttons with LCD monitors and touchscreens. “We’ve been upgrading our plants with SYSTEMS’ TSC to achieve the same results,” he said. “We can now configure and arrange buttons and indicators to allow our operators to better run the plant in a much less cluttered environment,” Moulton said. “And like pilots, our operators can now ‘fly’ their plants more efficiently, not having to move all over the control center to do their work.”
