摘　　要：概述了水泥混凝土路面和沥青路面的优缺点。通过分析水泥混凝土路面的结构与基础,得出水泥混凝土路面破坏的原因有:施工过程中的偷工减料;路基压实度不足;基层含灰量不够,压实度不足,水稳施工质量差;汽车超载,尤其是重型车辆超载;水泥路面排水不好,造成水进入路基,导致路面发生"变形+沉降"。Based on the analysis on the advantages and disadvantages of cement concrete pavement and asphalt pavement, and the structure and foundation of cement concrete pavement, this paper summarizes the reasons for the pavement failure：Jerry- built in construction process ; lack of subgrade compaction ; inadequate grassroots ash content,inadequate compaction and poor water stability ; vehicle overloading , especially heavy vehicle overloading ; ＂deformation ＋ settlement＂ of the pavement due to poor drainage and water infiltration.

关 键 词：水泥混凝土路面 沥青路面 基础
