摘要
通过建立排水性沥青路面结构的三维仿真模型,分析在不同的中面层厚度、层间接触条件以及环境温度的影响下,面层层间界面的力学特性。进而通过排水性沥青路面面层结构的剪切试验,结合有限元计算结果分析评价排水性沥青路面结构层间界面实际使用性能及特点。研究成果为排水性沥青路面的结构设计提供理论分析和试验依据,为路面铺筑施工提供指导意见。
The surface layer interface mechanical characteristics under different thickness of middle course,the contact condition between layers and environmental temperature are analyzed by establishing the 3D model of drainage asphalt pavement structure. Then performances and characteristics of surface layer interface in drainage asphalt pavement structure are evaluated by shear test combined with the results of finite element calculation. This conclusion can provide theoretical analysis and experimental basis for drainage asphalt pavement structure design and suggestions for pavement construction.
