摘要
针对沥青混凝土路面普遍存在的温缩裂缝问题,对沥青面层在温度应力作用下的力学状态进行了分析。用Mohr-Conlomb方程表示面层与基层之间的剪力,同时以面层抗拉强度为指标提出了面层温缩裂缝间距的确定方法。考虑了沥青粘弹性对裂缝间距的影响,最后有限元数值模拟表明,裂缝间距模型是合理的。
Concerning with the crack widely exiting in the AC pavement, this paper has analyzed the thermal stress of the pavement The shearing stress between surface layer and base is depicted by Mohr-Conlomb equation, at the same time, the method to determine the crack spacing is forward according to the strength of the surface layer, the viscoelastic property of the ac pavement is considered as well, at last, the accordance of theoretical results and FEA results approved that the model is rational
