基层模量对沥青路面结构的力学响应

摘要

With unchanged structural parameters of asphalt pavement, the distributing rules of internal stress, strain and deflection of overall pavement structure is studied through adjusting base course modulus of pavement on the basis of BISAR3.0 software, and the influence of the change of base course modulus of asphalt pavement on structural layer of asphalt pavement is analyzed, which means much to reasonable selection of structural parameters of pavement and composite design of structural pavement.%在沥青路面结构参数均不变的情况下,基于BISAR3.0软件,通过调整路面基层的模量来研究整个路面结构内部应力、应变和弯沉的分布规律,分析了沥青路面基层模量的变化对沥青路面结构层的影响,对合理选择路面结构参数,作好路面结构组合设计工作具有重要意义。
