大广高速吉安至南康段路面综合性能分析与评定

Thesis title Analysis and Evaluation of Comprehensive Pavement Performance of Daguang Expressway from Ji′an to Nankang

以大广高速吉安至南康段路面为研究对象,从路面破损状况、车辙、行驶质量和路面抗滑性能四方面对路面状况进行调查统计,在此基础上计算路面技术状况指数,评定路面技术状况等级,评估路面综合性能。研究表明,该段沥青路面技术状况良好,综合路面破损状况指数PCI、车辙状况指数RDI、行驶质量指数RQI均为优,路面抗滑性能指数SRI为良,综合技术状况指数PQI为93.83,路面病害针对性处治后可以继续服役。

Taking the road surface from Ji’an to Nankang section of Daguang Expressway as the research object,the road surface conditions are investigated and statistics from four aspects:road damage,rutting,driving quality and road anti-skid performance.On this basis,the road surface technical condition index is calculated and the road surface technology is evaluated.Condition level to evaluate the overall performance of the road surface.The research shows that the technical condition of the asphalt pavement is good,the comprehensive pavement damage index PCI,rutting condition index RDI,and driving quality index RQI are all excellent,the pavement anti-skid performance index SRI is good,the comprehensive technical condition index PQI is 93.83,and the pavement is diseased.You can continue to serve after targeted treatment.
