结合宣大（宣化-大同）高速公路改建项目分析水泥混凝土路面使用性能评价原则、指标及方法。采用人工方法调查路面的损坏状况，车载式激光平整度仪测定路面平整度，摆式仪测定路面的摩擦系数，得出路面损坏状况指数 PCI 、路面行驶质量指数 RQI 、路面抗滑性能指数 SRI ，进而得到路面使用性能指数 PQI ；并采用落锤式弯沉仪测定路面弯沉值，得到路面结构强度指数PSSI 。综合评定宣大高速公路现有路面使用性能，并提出相应的处治方案。

Combining the evaluation principles,indexes and methods of concrete pavement performance of Xuanda(Xuanhua-Datong)highway reconstruction projects,this paper investigated the concrete pavement distress condition by artificial methods,detected the pavement evenness with vehicle-mount-ed laser,measured the friction coefficient of road surfaces,which were used to calculate Pavement Surface Condition Index (PCI),Riding Quality Index (RQI),Skidding Resistance Index (SRI),ob-tained Pavement Quality or Performance Index (PQI).And via using the FWD to measure pavement deflections,the pavement get the pavement strength index(PSSI).Finally the paper gives the compre-hensive evaluation of the pavement performance and put forward the management measures.
