| In this paper, pavement dynamic loading was obtained from field data of pavement unevenness by Quarter-truck vehicle model.Then, finite element software NASTRAL was employed to investigate the structural response of 2-Dimensional asphalt pavement under different type of excitation, as well as the influence of pavement parameters on the stresses and deflection of the pavement.The effects of arbitrary loading on asphalt pavement were also analyzed.Finally , the structural response of 3-Dimensional asphalt pavement subject to excitation was studied. |
