Abstract: 

A variety of factors such as amount of load, velocity, wheel impact, time (loading rate), rest periods, temperature, and stress state, loading modes, aging and moisture can affect the asphalt behavior against deformation and efficiency. One of the most important factors is the effect of velocity on the tensile strain of the asphalt sub-layer, which leads to the most common type of failure (fatigue). In this study, using Abaqus, Ansys and 3D move soft wares, the desired and then a comparison between these three soft wares has been made. Dynamic modeling is conducted relying on the elastic behavior of layers. The study also includes the impact of loading speed on tensile strain of asphalt sub-layer. Results have indicated that Abaqus software compared with Ansys operates faster and more comprehensive for pavement analysis. In addition, 3D move compared with Abaqus and Ansys operates more rapidly in various model of the visco, but Abaqus has a more varied and stronger dynamic analysis. The comparisons between different velocities showed that high velocities include less fatigue failure. In general, the impact of velocity on the tensile strain in the asphalt sub-layer is more remarkable at low velocities. At low velocities, changes occur due to approaching to the static mode.
