沥青路面超载作用下力学性能敏感性分析

在不同荷载条件下变化沥青路面结构层的模量,找出沥青路面在超载作用下随结构参数变化路表弯沉、面层拉应力、基层拉应力、底基层拉应力和土基顶面压应变等力学性能及路用性能的变化规律,针对超载作用下的沥青路面要合理控制各结构层之间的模量关系,同时提高土基模量.为超载作用下沥青路面设计、施工提供理论依据.

Mechanical Properties of Asphalt Pavement Sensitivity Analysis Under Overload

By changing asphalt pavement layer modulus under different load conditions,the mechanical properties and pavement performance variation of the surface deflection,surface tensile stress,sub-base tensile stress,subgrade tensile stress are determined with the structure parameters changing of the asphalt pavement under overload.The overloading asphalt pavement should reasonable control the relationship of the layer modulus and increase the subgrade modulus.It provides a theoretical basis for the design and cons...
