TL;DRAbstract

This thesis presents the results of the experimental testing program performed at the Accelerated Pavement Load Facility (APLF) of Ohio University on four pavement test sections.The influence of load, temperature, offset, and thickness on the pulse duration and strain at the bottom of the asphalt concrete layer is discussed.A threedimensional finite element model is developed in Abaqus.This numerical model prediction was compared to the results brought by the response model of the Mechanistic-Empirical Pavement Design Guide (MEPDG).The results of the experimental testing showed that the applied load does not affect the longitudinal pulse duration and that the influence of the offset depends on the magnitude of the applied load.Furthermore, the influence of the temperature on the mentioned variable is more significant at a high value (104F) when it is compared to intermediate (70F) or low values (40F).In regards to the thickness, it was seen that the peak longitudinal tensile strain dec
