预防性养护效果与养护时机关系密切,但目前尚不能准确把握预防性养护时机,导致养护效果不能达到预期。本文结合浙江省普通国省干线的路况检测数据,采用了基于养护效果的养护时机确定方法和基于路况衰变规律的养护时机确定方法,提出了浙江省普通国省干线沥青路面的预防性养护时机,对指导预防性养护工作具有重要意义。
The effect of preventive maintenance is closely related to the timing of conservation. However, the timing of preventive conservation can not be accurately grasped at present so that the conservation effect can not achieve the expected result. In this paper, based on the detection data of the traffic conditions of the common national trunk lines in Zhejiang Province, the method of determining the maintenance timing based on the conservation effect and the maintenance timing method based on the decay of the road conditions are adopted. Preventive maintenance time is proposed for ordinary asphalt pavement in Zhejiang Province. It is of great importance to guide the preventive maintenance work.
