EXPERT ADVICE for KM International, North Branch, Mich. described several methods: • Asphalt recycling by means of a mobile asphalt recycler. Millings and asphalt chunks are loaded into a machine, then mixed, tumbled, dried out, new asphalt cement is added and the end result is recycler asphalt. • Infrared recycling which occurs as an inplace designated repair area using an infrared asphalt recycler to scarify, lute, and compact. • Hot In-Place Recycling is achieved by a large machine scarifying an entire road lane and then another machine rejuvenating and then compacting the material back into place. • Asphalt Plants have also started to use Recycled Asphalt Product (RAP) as part of their production process. As an option, Soft Heat Mfg., based in Plains City, Ohio, offers a portable asphalt reclaiming unit that heats the existing asphalt already in place and allows the contractor to rework it and add more asphalt if there is a void to fill. “We refer to the reclaiming of asphalt as returning it to a usable and workable state,” said Dave Price, president and developer with Soft Heat Mfg. “The idea is that every contractor can use bunked up asphalt product instead of hauling leftover new product to a dump. The reality is that cold and unused new product is readily available as leftovers all the time and can be reclaimed at 200 pounds at a time, in less than seven minutes. One can reclaim old asphalt as well, if it’s in chunks that are shoe-box size or smaller.” Price continued: “When you consider that left over asphalt mix gets dumped every day, and at a cost to do so, that with proper equipment, it can be reclaimed at great profit. There is no need for rejuvenators, no mixing required, and the weather season or temperature does not matter. This is an ideal product for patchwork and repairs as well as to fill and level damaged surfaces. If you think about it, this is recycling at the front line and at its best!” There are various types of equipment that can be used to recycle asphalt. “There are asphalt hot boxes and recyclers that can be equipped to reclaim virgin uncompressed asphalt or recycle RAP or asphalt millings,” stated Ric Simon, executive vice president, Falcon Asphalt Repair Equipment, Freeland, Mich. “For example, our trailer-mounted, slip-ins and hooklifts can be equipped with dual burners to enhance the reclaiming and recycling of asphalt in an overnight process. Once recycling is completed in the machine, it can be transported to the repair location in the same vessel it was recycled in. You load the materials into the Falcon Hot Box & Recycler, heat it overnight, transport the machine with hot recycled asphalt to the repair areas and fill the potholes.” Simon added: “From a ‘green initiative’ and care for the environment standpoint, the ability to use RAP versus new hot mix is certainly a benefit.” Recycling requires less energy than producing new. Most roads are made from concrete or asphalt. Mining the raw materials for either product requires massive amounts of energy and disrupts the environment from which they are extracted.
