This paper established a three-dimensional model of asphalt pavement by finite element analysis method, studied the effects of vehicle braking on the asphalt pavement, and analyzed the mechanical law of asphalt pavement through comparing the stress of pavement asphalt when the vehicle is in uniform motion or braking condition. The results show that the vertical stress, vertical displacement and horizontal shear stress of the asphalt pavement increase significantly while the vehicle is under the braking condition. In every asphalt pavement structure layer, the maximum horizontal shear stress under vehicle braking condition are all about four times to that of under vehicle uniform motion, so it’s necessary to significantly improve the shear strength of the asphalt pavement in these sections which often bear automobile braking force.
