An Electric Road System (ERS) is one option to enhance the operating range of battery electric vehicles without stops for charging. A comprehensive study of the performance of a road structure with an embedded ERS has been carried out with a Heavy Vehicle Simulator (HVS). The rail for conductive dynamic charging while in motion is placed between the wheel paths in the road. In the first phase of the study the ERS system was subjected to overpasses of a truck tire loaded to 6 kN in dry and wet conditions until the beginning of failure. The overpass test was performed to check how many times a truck could make a lane change, crossing the ERS. In the second phase the performance of the road structure with an ERS installed was evaluated with the HVS. The road structure was a typical Swedish high[1]capacity road structure where the bound asphalt layer thickness was 210 mm thick placed on 500 mm unbound layers of crushed rock. Strain gauges and pressure cells were placed in asphalt layers close to the ERS and in a reference area. The responses from the gauges were compared and analyzed considering the typical lateral wandering of heavy vehicles on Swedish motorways. The conclusion is that the structural performance of the road with an ERS installed, and the reference road are similar.
