基于车辙量预估的路面设计方案比选

The Selection and Comparison of Pavement Design Scheme Based on the Amount of Rutting Prediction

车辙是影响重载地区沥青路面使用性能的主要病害,对路面车辙量进行科学合理的预估,进而根据车辙预估量,调整路面结构,形成基于车辙预估量的路面设计方法,具有重要的意义。以阳蟒高速公路沥青路面设计为例,针对柔性基层和半刚性基层两种路面结构进行了车辙量预估,预估结果表明,柔性基层车辙量要明显小于半刚性基层,为车辙预估模型的建立与路面结构的选择提供了借鉴。

Taking Yangmang Highway asphalt pavement design as an example, in view of two kinds of pavement structure of the flexible base and semi-rigid base, this paper predicted the amount of rutting. The prediction results showed that the amount of flexible base rutting prediction was significantly less than that of the semi-rigid base, which provided the reference for the establishment of rutting prediction model and the choice of pavement structure.
