Abstract: The mechanical response of asphalt pavement under different condition of dry-wet subgrade was studied byBISAR3 software from the perspective of pavement mechanics． The change of the displacement, normal stress and shearstress of every layers were analyzed by roadbed resilient modulus and connection status between the layers． The results shows that subgrade dry-wet state has great influence on asphalt pavement structure, especially the displacement and the bottom normal stress and shear stress
