摘要
采用PG 82 SBS改性沥青GAC-16罩面对广东阳茂高速中存在连续坑槽、路面损坏状况指数PCI值偏低的路段进行养护,这在很大程度上改善了原道路的使用情况。大约半年后对罩面进行进行性能检测,发现罩面养护路段具有较好的抗高温车辙及抗渗水能力,而且可以有效预防反射裂缝。这一专项养护工程给大交通量和重载交通道路的养护工程提供了重要的参考价值,并为推动PG 82 SBS改性沥青及GAC-16罩面的应用产生了积极作用。
The GAC-16 overlay with PG 82 SBS modified asphalt was used to maintain the section of Guangdong Yangmao Expressway with continuous potholes and low pavement condition index PCI values, which largely improved the use of the original road. About half a year later, the performance of the overlay was tested, and it was found that the overly had a excellent resistances to high-temperature rutting and water permeability, while effectively preventing the reflective cracking. This special maintenance project can provide an important reference value to the maintenance project of roads with high traffic volume and heavy traffic, and has a positive effect on promoting the application of PG 82 SBS modified asphalt and GAC-16 overly.
