Abstract: According to the pavement under different cases, such as the standard axle load, overload, at room temperature and high temperature,with or without load level,mechanical response of asphalt pavement internal shear stress and road surface deflection by different layers of high modulus asphalt mixture is studied. The result shows that the high modulus asphalt mixture can significantly reduce the internal shear stress and road surface deflection of the asphalt layer when it is used in the upper middle layer. Otherwise,the effect when it is used in the bottom layer is not obvious. The results of this paper can provide a theoretical basis for the design of asphalt pavement.
