一、概述道路是国民经济发展的重要基础设施,随着我国交通事业突飞猛进的发展,城市道路状况得到了明显的改善。然而,随着城市道路里程大幅度增加,一些新建道路通车时间不长就出现了不同程度的路面早期破坏现象,常表现为早期的微小裂缝、早期车辙和平整度的衰减、泛油和抗滑性能的下降、细料失落导致的露骨、磨光、路面渗水等表面病害。这些病害如不能在早期处理而任其发展下去,则必然进一步导致表面松散,或由于渗水而导致下层剥落以及深度车辙 I. Overview The road is an important infrastructure for the development of the national economy. With the rapid development of transportation in our country, the road conditions in urban areas have been significantly improved. However, with the significant increase in urban road mileage, some new roads have been in traffic for a short period of time and have experienced various degrees of early damage to the road surface. They often show early tiny cracks, early rutting and flattening attenuation, oil flooding and anti-skidding Degradation of performance, faded material caused by explicit, polished, surface water seepage and other surface diseases. If these diseases can not be allowed to develop in the early stage of treatment, it will inevitably further lead to the surface loose, or due to seepage caused by the lower spalling and depth rutting
