| 摘 要： | 分析了现行水泥路面养护技术规范,提出了适用于旧水泥混凝土路面养护和罩面需求的水泥路面性能评价指标体系和评价方法。采用路面状况指数、行驶质量指数和国际摩阻系数等指标评价路面的使用性能,采用断板率、基层顶面当量回弹模量、接缝传荷能力和板底脱空率等指标评价路面的结构状况。考虑到各评价指标分级的模糊性,应用模糊物元分析法建立了多指标的路面状况评定方法,其中的权重确定综合了AHP法和熵值法,以求同时反映评价分级的主观性和实测数据的客观性。分析结果表明:实际路段的路面性能对应"中"的关联度最大(0.562 4),对应"次"的关联度次之(0.319 4),根据最大关联度原则,该路段的路面性能属于"中"级偏"次",与实际情况相符,表明评价指标体系和方法可行。

| Abstract: | The needs of maintenance and overlay for Portland cement concrete pavement(PCCP) were considered,the current Chinese technical specifications of cement concrete pavement maintenance were analyzed,and new evaluation index system and method were put forward.Pavement condition index(PCI),running quality index(RQI) and international friction index(IFI) were used to evaluate the functional performance of PCCP.The ratio of broken plate(DBL),the resilience modulus of base course,the load transferring capacity of t... |
