| 摘 要： | 现有的旧路状况评价体系侧重于养护对策,并不适用于高速公路改扩建工程的需要。针对连霍高速公路郑州段的旧路状况,以PQI评价指标的基本原则出发,以路面结构强度指数（PSSI）为主要判断基础,以路面损坏状况指数（PCI）和路面车辙深度指数（RDI）为辅助判别,并根据不同的重要性分别赋予相应的权重值,最终得到适合于改扩建工程的路面使用性能综合评价指数PCQI,并对不同车道、不同判断级别的路段提出了相应的处理措施,实践应用表明评价成果与实际工程情况相符。

| Abstract: | The present evaluation system of existing road condition is emphasized in maintenance countermeasure,which is not suitable for reconstruction and extension project of expressway.According to the existing road condition in Zhengzhou section of Lian-Huo expressway,starting from basic principles of PQI,the pavement structural strength index(PSSI) to determine the main base,the pavement condition index(PCI) and pavement rutting depth index(RDI) is a supplementary discriminant,and depending on the importance of ... |
