辽宁省高速公路超薄磨耗层性能评价研究

Research on Performance Evaluation of Ultra-thin Wearing Course of Expressways in Liaoning Province

为了对辽宁省高速公路超薄磨耗层技术使用效果进行评价研究,通过对辽宁省近年来超薄磨耗层技术的应用情况进行了调查总结,利用多年路面性能检测数据,对超薄磨耗层实施后的路面状况指数、车辙、抗滑性能、平整度等指标进行对比分析;对具体病害特征进行原因分析,提出了保证和提高该项技术路用性能的技术建议。

In order to perform the evaluation research for the using effect of the technology of ultra - thin wearing course of expressways in Liaoning province, the investigation summary is made for the application situation of the technology of ultra - thin wearing course in recent years, the contrastiveanalysis is made on indexes like index of pavement situation, rutting, anti - slide performance, flatness and so on after the implementation of ultra - thin wearing course by utilizing many years＇ pavement performance test data, and the reason analysis is made on characteristics of specific diseases. The technical proposal of guaranteeing and improving the pavement performance of this kind of technology is put forward.
