Applicable Conditions and Design Gist of Old Cement Concrete Pavement Overlay Asphalt Concrete Layer

旧水泥混凝土路面加铺沥青混凝土面层由于其施工的便利性和造价的经济性在目前的旧水泥路养护改造过程中得到广泛应用,并取得了很好的效果,但此改造方式在实际应用中面临诸多限制,如旧路路面损坏状况及两侧建筑物地坪标高限制等。对其适用条件进行了分析,并提出了设计要点,有关经验可供相关专业技术人员参考。

Old cement concrete pavement overlay asphalt concrete layer has been widely used in the current maintenance and reconstruction of old cement road because of its construction convenience and the economic cost,and has achieved good results.However,this reconstruction method is more limited in the practical application,such as the damage status of old road pavement and the limited floor elevations at the two sides of the buildings.The article proposes the design gist.The relative experience can be referenced for the similar bridges.
