The U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory’s Heavy Vehicle Simulator is shown with the new infrared heating system panels installed in the lower area. The IR system was designed, fabricated and built in five weeks by a team with CRREL’s Engineering Resources Branch. This heating system will allow researchers to test hot mix asphalt year round, keeping the test area at a continuous temperature (ambient to more than 120 degrees Fahrenheit/ 49 degrees Celsius).
