In order to study the stress and the displacement of the flexible multi-layered elastic pavement under various loads distributed in arbitrary shape, the boundary element method for the flexible layered pavement was presented using the fundamental solutions multi-layered solids for the analysis. With combination of the generalized Kelvin fundamental solution and the boundary element method, the boundary integral equation was established for the boundary value problem of the flexible layered pavement to explain the singular integral appearing in the kernel function. The method, which does not involve integral of layered material’s interface, can be used to solve the stress and the displacement of the multi-layered elastic media under various loads distributed in arbitrary shape. The analytical result shows that the present method is of higher precision and can be used for analysis of the flexible pavement which mechanical parameters change along the depth because of using the generalized Kelvin fundamental solutions of layered elastic solids.
