| 摘 要： | 为了防止沥青路面车辙的产生,分析了沥青路面结构最大剪应力的产生和分布．结果表明,当面层相对刚度很大而厚度较薄时,垂直荷载在路面面层的一定部位产生较大的剪应力,剪应力的过度集中是路面产生车辙等剪切破坏的主要原因．为克服和减少沥青路面结构车辙,除应以设计弯沉为结构设计控制指标外,还应增加水平荷载的控制参数．

| Abstract: | Through the analysis of generation and distribution of the maximal shearing strength in the bituminous pavement, it is discovered that the vertical load may make shear strength increase when the relative stiffness is bigger and the thickness is thinner at the crossing of city roads, especially of high velocity and over loading. Exorbitant centralization of the shear strength leads to cut demolishing. In order to overcome and reduce asphalt pavement rut, we should consider the design of the material and the ... |
