The Federal Highway Administration's (FHWA) Truck Pavement Interaction (TPI) research program has initiated a cooperative research to investigate the potential impact of the North American Free Trade Agreement (NAFTA) overloading on US highway pavement performance. The research is in cooperation with the states of Texas, New York and Louisiana under national fooled fund study SPR2(205). In this study, major classes of NAFTA trucks with their axle configurations and load limits were first identified; then a procedure of simulating pavement damage was developed. Simulations using the calibrated pavement primary response and performance model VESYS 5 was performed. Based on simulation results, vehicle damage factors (VDF) and vehicle payload factors (VPF) for each class of truck at different axle configuration were determined. The VPF relates the total pavement damage to payload haul by a specific truck and axle configuration. It is intended to be used as an overall indicator of how highway pavement serviceability will be affected by a vehicle class transporting a known quantity of payload.
