摘　　要：按照我国现行沥青路面设计规范,在倒装结构中采用较薄的沥青面层厚度,沥青层的拉应力反而较小,层底拉应力验算很容易通过,容易误导公路技术人员设计一些较薄沥青面层的不合理倒装结构。详细分析了沥青面层厚度对倒装结构各结构层应力的影响情况,在此基础上,分析了我国高速公路倒装结构沥青面层的合理厚度应在12~18 cm。according to present specifications for design of expressway asphalt pavement of our country, the tensile stress of asphalt pavement is instead smaller if we use the thinner asphalt pavement thickness in inversive structure. And more it is easy to mislead the road technical personnel to design some unreasonable inversive structure of the thinner asphalt pavement because the inspecting of level bottom tensile stress is very easy to pass. This article analysis the influence situation of thickness of asphalt pavement on various structures level stress in inversive structure. In this foundation, it is analyzed that the reasonable thickness of asphalt pavement in inversive structure is supposed in 12 - 18 centimeter in expressway.
