Abstract: Using ABAQUS finite element software to simulate the 3D asphalt pavement model, the strain, stress and displacement of each layer are calculated under the action of traffic ｌｏａｄ, then the influence of asphalt mixture uniformity on the mechanical response of asphalt pavement was obtained. The results show: the uniformity of asphalt mixture has an influence on the mechanical response of pavement; under the same environmental factors and traffic ｌｏａｄ, the displacement of the flexible base asphalt pavement is larger than that of the semi-rigid base asphalt pavement; the tensile stress generated in the asphalt pavement is basically on the surface of the base layer and the pavement layer, the tensile stress of semi-rigid base asphalt pavement is larger than that of the flexible.
