Investigation and Analysis of Guangxi Road Network Asphalt Pave-ment Defect

文章通过广西路网公路沥青路面大规模现场病害调查和室内试验,分析了路网公路沥青路面的主要病害类型及损坏特征,建立了路面残余空隙率、面层强度、油石比、基层强度等性能指标与路面损坏之间的关系,可为沥青路面设计及施工提供参考。

Through a big scale on site defect investigation and indoor test on asphalt pave-ment of Guangxi road network,the article analyzes the major defect type and failure charac-teristics.It builds a relationship between the degree of failure and pavement performance indexes such as residual pore ratio,surface strength,bitumen-aggregate ratio and the intensity of base,which provides reference to asphalt pavement design and construction.
