农村公路路面技术状况评定与养护研究

Study on technical condition evaluation and maintenance of rural roads

以某地区农村公路为研究对象,通过对路面破损、平整度等检测数据计算分析,汇总计算得到路面技术状况指数PQI得分及评价等级,在此基础上分析路面主要病害成因。结果表明:该地区农村公路路面沥青路面RQI得分为76.3,水泥路面RQI得分为74.6,路面损坏状况指数PCI为61.27,路面损坏评价等级为次,汇总计算得到PQI得分为66.8,评价为次;最后依据该地区农村公路路面路况的检测结果,提出了农村公路路面养护措施的处治措施,为该地区农村公路养护设计提供指导。

Taking rural roads in a certain area as the research object,through the calculation and analysis of the detection data such as pavement damage and smoothness,etc.the PQI score and evaluation grade of pavement technical condition index are summarized and calculated.On this basis,the causes of main pavement diseases are analyzed.The results showed:the RQI score of rural highway pavement asphalt pavement in this area is 76.3,the RQI score of cement pavement is 74.6,the pavement damage condition index PCI is 61.27,the evaluation grade of pavement damage is second,the PQI score was calculated to be 66.8.Finally,according to the detection results of rural highway pavement conditions in this area,the treatment measures of rural highway pavement maintenance measures are put forward.Provide guidance for the maintenance design of rural roads in the region.
