Sensitivity Analysis of Rut Depth to Longitudinal Measurement Location in Accelerated Pavement Testing with a Heavy Vehicle Simulator-Airfield
The FAA uses a heavy vehicle simulator-airfield (HVS-A) to conduct full scale performance testing on pavement surface layers at the National Airport Pavement and Materials Research Center at the William J. Hughes Technical Center. The HVS-A applies load to an instrumented test section approximately 36 ft in length. During trafficking pavement data including temperature, strain, pressure, and rut depth are collected. The data are then analyzed to characterize the pavement performance with respect to variables such as pavement temperature, tire pressure, and load. During analysis, rut depth is typically determined at a single location, but sensors are located along the test section. This implicitly assumes that pavement performance is uniform along the length of the test strip. Pavement cross sections collected at 4-in. intervals longitudinally throughout testing were compared to determine the longitudinal variation in rut depth and assess the sensitivity of rut depth to the choice of location at which rutting is determined.
