Abstract: In this paper,CRCP was regarded as a kind of composite meterial,its anisotropic elastic constants were analysed by method of micromechanics.By using the classical anisotropic thoery of antisymmetric composite plate,the equilibrium equations of pavement on Winkler foundation were established,and in the case of vertical load expressed by double Fourier’s series,solutions of the equations were obtained. An example was also given.
