| Abstract: | Numerical simulation analysis about heavy-loaded asphalt pavement was performed using elastic and elastic-plastic theories with finite element analysis software ANSYS,and the mechanical responses of pavement in two cyclic traffic loads were studied.Proposing that increases the pavement design target such as tensile strain of asphalt bottom layer and road bed pressure strain. |
