平整度、粗糙度、强度是高等级路面三项最重要的质量指标,但影响因素很多,施工控制难度最大的则是平整度指标。因为,从路基到路面,从级配到拌和,从摊铺到辗压等,施工中的每一个环节,都与它有非常密切的关系,只要其中有某个环节出现失误,路面平整度都会直接或间接受到影响和损害。 Flatness, roughness and strength are the three most important quality indexes of high-grade pavement, but there are many influencing factors. The most difficult for construction control is the flatness index. Because, from the subgrade to the road, from grading to mixing, from paving to rolling, etc., every aspect of construction, and it has a very close relationship, as long as there is a link in some mistakes, the road surface will be flat Directly or indirectly affected and damaged.
