Heatwurx Inc., an asphalt preservation and repair equipment manufacturer headquartered in Greenwood Village, Colo., has announced that the U.S. Army Corps of Engineers has completed its evaluation of equipment and materials for the U.S. Air Force's Sustained Pavement Repair (SuPR) kit for in-place asphalt recycling. The report, Laboratory and Field Evaluation of In-Place Asphalt Recycling Technologies for Small Airfield Repair, concluded that "the in-place asphalt repair technology, including the use of rejuvenator and asphalt infrared heater, proved to be effective in terms of repair times and repair quality."

The Air Force Civil Engineer Center (AFCEC) sponsored the research project with the main purpose "to determine the most expedient methods, materials and equipment for small-to-medium repairs in damaged airfield asphalt concrete (AC) pavements using in-place asphalt recycling technologies." 

The U.S. Army Engineer Research and Development Center (ERDC), in collaboration with Applied Research Associates (ARA), was tasked to evaluate and test equipment for performing sustainment repairs in damaged airfield asphalt pavements that will give military engineers the capability for in-place asphalt recycling.

According to Heatwurx, based on the laboratory and field-testing, the ERDC recommended the use of an electric infrared heater and asphalt processor for the SuPR augmentation kit because it meets the Air Force's performance, reliability, transportation, and eco-friendly recycling requirements. The Heatwurx HWX-30 Electric Infrared Heater and HWX-AP40 Asphalt Processor were identified in the report as the equipment that best met the requirements of the Air Force for this program and were included in the ERDC's recommended equipment list.

Heatwurx notes that the reference is the second major recognition for the company. Last year, the company's Hot-in-Place Asphalt Pavement Recycling Process was selected as an "Additionally Selected Technology" by the Technology Implementation Group (TIG) of the American Association of State Highway Transportation Officials (AASHTO). The organization identifies and advocates the implementation and/or use of a select few proven technologies, products or processes that are likely to yield significant economic or qualitative benefits.

"The in-depth testing and evaluation of our equipment by the world’s largest public engineering, design, and construction management agency, coupled with the recognition from AASHTO, who sets the standards for this country's roadways, further supports the use of Heatwurx equipment and processes as the innovative, cost-effective, and environmentally conscious way to preserve and repair our roadways," says Stephen Garland, Heatwurx' CEO. "Heatwurx provides real quantitative value to local, state and federal transportation and public works agencies responsible for maintaining and keeping our roads safe."
