| Abstract: | The model of dynamic properties for asphalt pavement was established based on the principle of finite element. Then model accuracy was verified through comparative analysis with measured data. Under FWD, the influences of surface thickness, modulus, loading speed on dynamic behavior were studied. Results contributed to pavement structural optimal design and damage analysis |
