基于重载交通的沥青路面受力特性及病害防治措施研究

The Study on the Mechanical Characteristics & Disease Prevention and Control Measures of Asphalt Pavement Based on the Heavy Traffic

随着我国公路交通不断发展,路面早期破坏也不断加重。通过对山西省轴载、交通量及路面的调查,确定山西省的路面交通组成特点,深入研究重载条件下的路面受力特性,对山西省8条高速公路的病害进行分析,提出从设计施工阶段到运营养护各个阶段的预防性与治理措施的建议,保证了道路的正常服务能力。

Through the investigation of axle load, traffic volume and the pavement in Shanxi Province, this paper determined the road traffic composition characteristics in Shanxi Province. It further studied the pavement mechanical characteristics under the heavy load condition. It analyzed the diseases of eight expressways in Shanxi Province, also put forward the suggestion of preventive and control measures from the design construction stage to all stages of operation and maintenance, which ensured the normal service capacity of the road.
