Abstract: The motion of the vehicle is a major cause of road damage. Through on the vehicle dynamics re-search, to reveal the mechanism of pavement damage, improve pavement structure type, is a hot problem in the study on the current road boundary. For mechanical response under the action of vehicle ｌｏａｄ and speed of pavement problems, based on the asphalt pavement as the research object, using the dynamic vehicle to simulate the vehicle ｌｏａｄ and speed on the mechanical response of pavement. Through the model establishment and ANSYS  finite element analysis method on the vehicle's impact on pavement mechanics.

Keywords: asphalt pavement; vehicle ｌｏａｄ; the speed of the car. the finite elemen.
