| With the rapid development of the high grade highway of Shaanxi Province, the asphalt pavement at semi-rigid base is used widely. However, the structural serviceability are not coordinated with functionality serviceability in the asphalt pavement, which is designed by the traditional method ,and some early disease and functional disorder appear. Because the material design and the structural design of the asphalt pavement at semi-rigid base is incongruous. In this paper, the inside stress and emergency of asphalt pavement at semi-rigid base of Shaanxi Province typical pavement structure are analyzed to get the position of layer resist high temperature rut area, resist tired to destroy area and resist facture in low temperature, and confirm the structural function of three layers in asphalt surface course of the typical pavement of the high grade highway in Shaanxi Province, guide the choice of material of pavement surface, realize the material design and the structural design integrating of high grade the asphalt pavement at semi-rigid base. |
