![]() This challenging HVS upgrade involved CRREL’s in-house design and fabrication of an infrared heating system. The most recent upgrade involves two new systems for heating and cooling of the pavement test section under the HVS from 15 degrees Fahrenheit to more than 120 degrees Fahrenheit (minus 9 to 49 degrees Celsius) for year round testing. ![]() The Heavy Vehicle Simulator (measuring 75 feet long, 12 feet wide, and 12 feet high and weighing 51 tons) when testing can apply heavy loads, while conducting up to 10,000 passes per day simulating truck and airplane traffic.ĬRREL’s ERB staff members Civil Engineering Technicians Charlie Smith and Andy Bernier have been working to modernize the HVS and other supporting equipment in order to conduct pavements testing more safely, reliably and cost effectively. ![]() Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory has drawn on and utilized a broad range of in-house capabilities to provide the lab’s trafficking tool, the Heavy Vehicle Simulator, additional capacity for testing pavements year round.
