| Abstract: | Adopting the three - dimension finite element static analysis method, the authors calculate and analyse the old cement concrete pavement which was joined asphaltum overlayer under the wheel load stress along with the change of the base course thickness. The paper takes a deep study of the effect of the different base course thickness to the asphaltum overlayer reflectional crack, set forth the great effect of the base course thickness to the asphaltum overlayer load stress, and put forward the best base course thickness when the thickness of the asphaltum overlayer is definite. |
