| Based on the study of traffic features of cement concrete pavement, the suitability and limitation of fatigue equation which is now adopted in the specification is analyzed in this paper. By analysis of fatigue test results existing and add some more to complete it, a whole stress level cement concrete fatigue equation combined with a axle load conversion method is put forward. Meanwhile, the problem of fatigue lean cement basecourse cement concrete pavement under the comprehensive load of axle and temperature stress is concerned in this paper as well.. |
