Asphalt Product Gallery: December 2016
AsphaltPro sets the standard for equipment and service information by focusing on what’s new in the industry. This product gallery focuses specifically on the production branch of our industry. Let’s take a look at the latest launches and upgrades that can influence and enhance your bottom line when it comes to the production of aggregates, binders and mixes. We’ll start with the team at Standard Filter Corporation, Carlsbad, California, and a technological advance you may have heard of already. Just this summer, a large asphalt contractor committed to using MIXLink at more than 100 of its plants across the nation, but the process began about six years ago. David Burig of Standard Filter Corp shares.
Plant Sustainability Migrates to the Cloud
In 2010, California’s South Coast Air Quality Management District (SCAQMD) implemented rule 1155, which mandated bag break detection devices on all hot mix asphalt (HMA) plant baghouses. With that ruling came regular inspections and the mandate that records be kept on-site to verify compliance. According to the ruling, the records must be “available immediately to the Executive Director of SCAQMD upon request.”
In 2012, Toby Wiik, president of Standard Filter Corporation, was speaking to a plant supervisor in Los Angeles about the onerous nature of the reporting and record keeping requirement. Wiik had seen a small PLC that could gather baghouse data and send SMS text messages. He then developed a program to send those messages to a server in the cloud. After successfully petitioning the SCAQMD to accept cloud data in lieu of on-site paper records, he launched the automated baghouse monitoring and record keeping system called DustLink.
Soon the plant owners asked if the system could keep track of other things, such as tonnage, burner fuel consumption and motor kW draw. The next logical step was to use this data to calculate plant efficiency in BTUs per ton, and the system evolved into what is now MIXLink. It tracks all of those key metrics and more, and they can be seen in real time from any computer or mobile device, and the data can be saved for immediate retrieval from anywhere. MIXLink will work on all OEM control system, acting as a bridge to unify data across all platforms.
“A plant manager can now sit in his office and see how efficiently all of his plants are running in real time,” Wiik said. “And at the end of each run, key efficiency indicators are logged on a summary page, that allow management to analyze the run at a glance. A detailed Excel spreadsheet is also generated, storing every aspect of the run in five-second increments.”
By clicking on a saved run on the summary page, users can bring up a graphic representation of that particular run. Efficiency can be compared from run to run, or from one plant to another. You can also compare the cost of the mix you just ran to the historical average for that mix.
Let’s consider efficiency. Every plant has its sweet spot—the rate at which it runs with the highest efficiency. But plant operators may not know where that spot is. MIXLink allows operators to see their efficiency on a flat screen in the control house, in terms of BTUs per ton and actual dollars per ton. Now operators can set visual target efficiency goals, basing them on the mix they’re running, so they have something to shoot for. Operators can tweak their run for more efficient operation as it’s happening. Real world data shows a reduction in fuel consumption of up to 20 percent when an operator can see the efficiency at which he’s running.
We tend to focus on burner fuel when we think about HMA plant efficiency, but power and demand charges can be reduced significantly if they are properly managed. How much does it cost to run your baghouse exhaust fans during an hour-long hot stop? MIXLink allows you to see the instantaneous and historical electrical current draw for your plant as a whole, or you can look at key power consumers individually. If a drum drive motor starts pulling more current than it usually does, it may be a sign that it hasn’t been lubricated, or a bearing could be going bad. Whichever it is, alarms can be configured to send notification via text message or email to the recipient of your choice when any parameter goes outside of user-defined limits. Alarms can be set for any parameters being monitored, including motor current, mix temperature, or if the ratio of AC to aggregate goes outside of recipe parameters.
When the last truck is loaded, there are reports to do. MIXLink can take the data gathered during the day’s production and create customized reports that fit the owner’s needs. MIXLink also captures and archives production data for access days or years later—this includes mix temperature, AC content and even weather conditions at the time a batch was made. Because the data is stored securely in the cloud, authorized users can access it at any time, from any computer or smart device.
MIXLink has grown to what it is today through customer input. These measurable data points are the points HMA producers have requested. The construction materials industry is already embracing cloud-based plant connectivity.

From Process Heating Company
Process Heating Company (PHCo), Seattle, continues to offer its Lo-Desnity® electric heat for asphalt producers in the unitized storage tank heaters, fuel-oil preheaters and hot-oil heaters. With fluctuating energy prices, efficiency becomes critical to the cost of doing business. Electric heat offers 100 percent energy efficiency throughout the lifetime of the heater, because all of the energy is used to heat. PHCo electric heaters typically last for more than 30 years, providing 100 percent efficient heat over their entire lifetime, according to the manufacturer. In addition, electric heaters can be interfaced and coordinated with other electrical equipment so that the load of the heaters can be reduced to base rates, thus preventing increased demand charges or peak-use rates, and lowering consumption cost.
PHCo’s unique drywell-style heaters are designed to dissipate controlled heat as low as three watts per square inch on the heater’s sheath to prevent coking or damaging of temperature-sensitive asphalt, oil and emulsion materials. Because the drywell-style elements are accessible from outside of the tank, they also may be serviced without draining the tank. Electric heat is environmentally positive because it heats without combustion or emissions.

From Stockpile Reports
Stockpile Reports, an inventory management system companies use to measure volume and tonnage of materials via drone, plane and iPhone-based measurement tools, released its new Verified Measurements feature June 13, 2016.
Stockpile Reports’ Verified Measurement feature gives a confidence score to each one of the stockpile measurements at construction and aggregate producer sites. When stockpiles are measured, there can be all kinds of measurement risks. Vegetation growing on the pile, standing water, equipment obstructions and more, all can cause big errors in a company’s inventory numbers. The Stockpile Reports system automatically highlights those risks, so companies can always have the insights they need to know whether to have crews do some pile cleanup and re-measure. Companies can almost eliminate write-offs and costly budget overruns.

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.
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.”
- Use this at loadout.

Volvo Construction Equipment, Shippensburg, Pennsylvania, introduced the A60H articulated hauler for use in the quarry, at the recent MINExpo. Powered by a 673-horsepower Volvo D16J engine, the A60H includes active hydraulic front suspension, hydro-mechanical steering and high ground clearance at the articulation joint. It features automatic traction control and 100 percent differential locks. It includes hill-assist, which is a new safety feature that holds the hauler in place on steep slopes without the need to engage the parking brake. The feature is designed to automatically activate when the truck arrives at a complete stop on a hill, and is disengaged when the operator accelerates. The dump support system is designed to allow the operator to see the percentage side inclination of the truck and set allowable parameters for safe operation. On-board weighing now comes standard and is fully automatic. Three load indicator lights alert both the hauler operator and the excavator when nominal load has been reached and can warn the operators of overloading.
