文章结合合肥市二环路(宿松路～马鞍山路段)旧水泥混凝土路面加铺改造设计,通过大量的技术分析及现场考察,较详细地阐述了旧水泥混凝土路面现状、交通量、旧水泥混凝土路面的病害处理、土工布及改性沥青的应用.实践证明,在旧水泥混凝土路面上直接加铺烧毛土工布能有效抑制和延缓反射裂缝的产生.

This paper deals with the design of repaving and reform of the Susong Road-Ma＇anshan Road section in the second ring road of Hefei City. A large quantity of technique analysis and spots investigation is carried out. A detailed discussion is made about the investigation and inspection of the old cement concrete roadway, the traffic census, the disposal of damage on the old cement concrete road, and the application of geosyntheties and modified bitumen. The practice proves that repaying singeing geosyntheties directly on the old cement concrete road can repress effectively the creation of reflecting cracks.
