由于高温、重载、车轮水平和垂直荷载的综合作用,导致沥青路面在交叉口等许多特殊路段出现拥抱、推移和车辙等剪切损害。抗剪强度指标的确立和应用具有非常迫切的意义。本文通过分析沥青路面的剪切破坏类型,以及路面结构类型、结构层厚度、温度、水平力系数和重载对沥青层剪应力的影响,给出了抗剪强度指标的设计和应用方法,提出针对不同的破坏模式应通过不同的途径解决路面剪切损坏问题。
Due to the combined effect of high temperature, heavy load, wheel horizontal and vertical load, asphalt pavement appears shearing, embrittlement, rutting and other shear damage on many special sections such as intersections. The establishment and application of shear strength index is of great urgency. This paper gives the design and application of shear strength index by analyzing the types of shear failure of asphalt pavement and the influence of pavement structure type, structural layer thickness, temperature, horizontal force coefficient and heavy load on the shear stress of asphalt layer. For different modes of failure should be resolved through different ways pavement shear damage.
