摘要
预防性养护将成为我国高速公路养护管理的发展方向,但在我国预防性养护理论研究尚处于起步阶段。本文针对沥青混凝土路面早期破坏现象,将裂缝、车辙、平整度和抗滑性作为基于预防性养护的早期性能评价内容,并对其进行了分级。根据分级,本文从技术角度提出了针对预防性养护的对策方法,这为高速公路沥青混凝土路面预防性养护的决策提供了理论依据,可供高速公路养护管理部门参考。
Preventive maintenance is the direction for development of expressway maintenance management, but the theoretical study in China is still in the initial stage. Against the early damages of asphalt concrete pavement, the evaluation contents including cracks, rutting, roughness and sliding are put forward and then graded. According to the grading, the countermeasure for preventive maintenance is also set up from the technical perspective. Therefore it can be used for the preventive maintenance countermeasure and as the reference for the highway maintenance management.
