沥青路面微表处养护措施长期路用性能研究

Research and analysis of long-term pavement performance of micro-surfacing treatment in asphalt pavement

通过对广东省七条高速公路近年来微表处实施路段各路用性能指标(PCI,RQI,RDI,SRI)的对比分析,研究各路段微表处措施实施后的长期路用性能,并对其三种常见的病害类型:纵向裂缝、横向裂缝和坑槽的累计增长趋势进行统计分析,结果表明实施微表后的各路段具有良好的抗滑性能和封水性能,可以有效的恢复和改善路面的坑槽、裂缝等各种病害。

Through the comparison and analysis of pavement performance indicators（ PCI, RQI, RDI, SRI） of seven highway which had imple-mented micro-surfacing treatment in Guangdong Province, Researching on long-term pavement performance of each section, and statistical analy-sis of three common types of diseases：longitudinal cracks, horizontal cracks and pit slots of the cumulative growth trend. The results showed that each section has the very good anti-sliding and sealing performance, what’ s more, can effectively restore and improve pits, cracks, and other dis-eases of the road.
