英国现行柔性路面结构设计方法,是1987年颁布实施的新建道路结构设计规范的一部分.该设计方法以永久变形(车辙深度)与疲劳开裂作为柔性路面结构厚度的设计准则,其极限条件是对新建柔性路面要求在设计年限内不能出现大于10mm的车辙深度;也不能出现因车辆荷载作用而产生疲劳裂缝.这种方法
The current flexible pavement structure design method in the United Kingdom is part of the new road structure design code promulgated in 1987. The design method takes the permanent deformation (rutting depth) and fatigue cracking as the design criteria for the thickness of the flexible pavement structure. The limit condition is that the new Flexible pavement requirements within the design life can not be greater than the rutting depth of 10mm; also can not occur due to vehicle load and fatigue cracks .This method
