Accelerated road testing facility

The CSIR-developed heavy vehicle simulator (HVS) is a high-tech field lab with unique instruments to measure and analyse the engineering performance of road structures and material layers. It simulates the damage caused by heavy traffic to road structures, in order to take make the correct decisions on road design, materials and methods before starting the construction of long stretches of road. Researchers can simulate the damage caused by traffic experienced over 20 years within short periods of approximately three months. It has been adapted and improved over the years to the current Mark VI version.

Various versions of the HVS have found their way to countries including the USA, Sweden, China and India. Eleven of these machines are now in operation worldwide. The two local HVS machines belong to the Gauteng Provincial Department of Roads and Transport and to the CSIR respectively.
