摘要
文章结合沥青面层和半刚性基层间的摩擦接触状况,分析沥青路面表面裂缝应力强度因子的变化规律,探讨了不同的面层厚度、不同的面层和基层模量以及不同的裂缝深度对应力强度因子的影响,为改进沥青路面的抗裂设计方法和表面裂缝的养护维修提供理论参考。
Considering the friction contact condition of asphalt surface and semi-rigid base,the change law of the stress intensity factor of asphalt pavement surface crack was analyzed under moving vehicle load.The effect of different surface thick-ness,surface modulus, base modulus and different crack depth was studied.Some theoretical reference was provided for improving the design method of asphalt pavement for resisting crack and for the maintenance and rehabilitation of asphalt pavement.
