摘要
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。
The relationships of pavement distress, roughness, strength condition with accumulative equivalent axles for typical pavement structures were analyzed according to the pavement condition, axle load and pavement maintenance in recent years. The variations of pavement performance of the typical pavement structure were analyzed, and the numbers of standard axle load that could be borne by typical pavement structures were evaluated according to the pavement distress, roughness and strength condition. The traffic load adaptability of semi-rigid baseasphalt pavement was summarized.
