宣大高速公路水泥混凝土路面使用性能评价

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。

Concrete Pavement Performance Evaluation of Xuanda Highway

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.
