摘要
为确定适合预防性养护的路况标准,为预养护决策提供依据,调研了国内外预防性养护路况标准的相关研究成果,并结合我国普通公路病害及养护特点,提出普通国省干线公路沥青路面预防性养护的宏观标准为:路面结构强度指数PSSI≥80,路面行驶质量指数RQI≥80(二级)、RQI≥75(二级及以下),路面损坏状况指数82≤PCI≤92(二级)、80≤PCI≤90(二级以下),路面车辙深度指数RDI≥75;同时提出了以路面病害严重程度表征的微观路况标准。
In order to determine the road condition standards suitable for preventive maintenance and provide a basis for preventive maintenance decision-making,this paper investigates the relevant research results on preventive maintenance road condition standards at home and abroad,and combines common road diseases and maintenance characteristics to propose preventive maintenance standards for asphalt pavements.The macro standards include the pavement structure strength index:PSSI≥80,smoothness index:RQ≥80(secondary level),RQI≥75(secondary level and below),and road damage index:82≤PCI≤92(ClassⅡ),80≤PCI≤90(Below ClassⅡ),and road rutting depth index RDI≥75.Micro road condition standard characterized by severity of road disease is also proposed.
