旧水泥砼路面加铺沥青面层的实践

Practices of Paving Asphalt Concrete Coverage on the Deterioration Portland Cement Concrete Pavement

介绍了旧砼路面上加铺沥青面层的设计与应用,包括旧砼路面的破坏病害调查,产生破坏病害的机理分析,采取加铺沥青砼面层设计时的旧砼路面处治方法和防裂措施,以及加铺沥青路面的使用效果.其成果对旧水泥砼路面的加铺改造设计、施工和质量控制具有参考应用价值.

Introduces the practices of paving asphalt concrete coverage on the deterioration rigid pavement, the deterioration state investigation, reasons analyses of concrete pavement deterioration and the thickness and fracture-prevent methods of as-phalt concrete coverage. The field application result shows that paving asphalt concrete coverage on the deterioration rigid pavement can obtain good effect under the condition that the cracking and breaking labs are fitly repaired.
