摘　　要：该文结合橡胶沥青应力吸收层在地下道路复合式路面结构中的应用。应用BISAR分析软件分析应力吸收层模量及厚度对层间最大剪应力的影响,随着应力吸收层厚度的增加,层间剪应力减小,层间剪应力随着应力吸收层回弹模量的增加而增大。同时结合实体工程介绍了了橡胶沥青应力吸收层的施工工艺及质量控制指标与方法,可供类似工程参考。The article analyzes the influence of stress-absorbing layer's modulus and thickness on the maximum shear stress between the layers according to the application of the rubber asphalt stress-absorbing layer in the compound pavement structure of underground road.With the thickness increment of the stress-absorbing layer,the shear stress between the layers decreases and the shear stress between the layers increases with the increment of rebound modulus of stress-absorbing layer.The article introduces the construction technology and the quality control index and method of the rubber asphalt stress-absorbing layer by the engineering cases,which can be referred for the similar projects.
