根据路面状况和车辆轴载的长期检测数据,以及路面养护维修历史数据,分析了几种典型路面结构下路面破损状况、路面平整度、路面强度与累计当量轴次之间的关系。根据所得到的典型路面结构的使用性能变化规律,分别按路面破损状况、平整度、强度指标估计路面结构能够承受的交通荷载作用次数,得到了典型半刚性沥青路面结构的交通荷载适应能力。
According to the pavement condition and the long-term test data of the vehicle’s axle load, as well as the historical data of pavement maintenance, the relationship between pavement damage status, pavement roughness, road surface strength and cumulative equivalent axis under several typical pavement structures is analyzed. According to the change law of serviceability of the typical pavement structure, the traffic load adaptability of typical semi-rigid asphalt pavement structure is obtained according to the pavement damage, flatness and strength index respectively.
