摘要
为了得到高速公路沥青路面使用性能指标之间的相关性及变化规律,对路龄小于3年的单条高速公路进行多次跟踪检测,对路龄大于3年的多条高速公路同时进行检测,得到了路面破损率、国际平整度指数、车辙、横向力系数、构造深度等指标值,分析了各项检测评价指标与路龄的关系以及各指标之间的相关性。研究结果表明,单路段各指标均具有较强的相关性,多条路段之间国际平整度指数与车辙深度、路面结构强度系数相关性较为明显。
To obtain the correlation and variation laws between the performance indexes of expressway asphalt pavement,this paper conducted multiple tracking detections on single expressways less than 3 years old and simultaneous tests on expressways more than 3 years old.The index values of pavement distress ratio,international roughness index,rutting depth index,lateral force coefficient,and tectonic depth were obtained,and the relation between each index and road age and the correlation between the indexes were analyzed.The results showed that the indexes of single road sections all had a strong correlation,and the correlation between the international roughness index and the rutting depth index and the pavement structural strength coefficient between multiple road sections was more obvious.
