Abstract: The road as a structural material is exposed to the natural environment, its performance will be af-fected by external environmental factors. As a black asphalt pavement partial flexible pavement, its traffic ｌｏａｄ and temperatures of the two major external contributing factor is very sensitive, because of this, most of the pavement mechanical response analysis focuses on two aspects. From the aspects of ｌｏａｄ analyzes the pavement structure under specific overloaded layers of bottom surface tensile stress and shear stress, the pri-mary layer bottom tensile stress, changes in surface deflection values. At the same time, the temperature change from the way their environment, analyzes the specific pavement structure under non-uniform temperature vertical displacement, vertical bending stress and tensile stress grassroots bottom surface with temperature changes. ｌｏａｄ factors and temperatures of the two cases on the road is a significant force in computing-related road mechanics can not be ignored.
