高速公路沥青路面使用性能评价及处治方案研究

The Evaluation of performance and The Study of Treatment Scheme of Freeway Asphalt Pavement

目前,我国高速公路已进入大规模的养护管理时代,对高速公路路面使用性能进行合理的评价,并制定科学的养护对策对高速公路的养护管理具有重要意义。以太原市南环高速公路为例,基于路面使用性能评价指标:路面损坏(PCI)、平整度(RQI)、车辙(RDI)、抗滑性能(SRI)、结构强度(PSSI),对沥青路面病害的损坏规律和损坏程度进行研究分析,提出了高速公路沥青路面病害的维修处治方案,对高速公路的养护决策具有参考意义。

At present,China has entered the large- scale maintenance and management t times of the freeway. It is very important for the maintenance and management of freeway to rationally evaluate the pavement performance and formulate scientific maintain countermeasure. Taking the south speed around the city in Taiyuan for example,the law and the extent of pavement surface disease based on pavement performance evaluation indexes： PCI,RQI,RDI,SRI,PSSI,is studied and analyzed. And the maintenance treatment scheme of freeway asphalt pavement is proposed,what is a important reference for the maintenance decision of freeway.
