随着国内公路网络逐渐成型,路面预防性养护暴露出了很多问题。路面预防性养护工作的质量是决定路面使用寿命的主要因素之一。预防性养护能否获得成功,并取得良好的经济效益,和养护的时机有关,但是,现阶段国际上有关养护时机的探讨和实践仍然存在不足,尚未找到合理解决方案。本研究在我国交通实际情况的基础上,以路面预防性养护为对象展开研究。文章以沥青路面为对象,为了解决其老化速率、渗水系数、路面平整性持续期、路面状况指数(PCI)等方面的问题,建立了针对沥青路面的功能性预防养护指标体系,从而促进沥青路面总体质量的提升。
With the gradual formation of domestic road network, many problems have been exposed in the preventive maintenance of pavement. Pavement preventive maintenance work quality is one of the main factors that determine the service life of pavement. Whether preventive maintenance can be successful and good economic benefits is related to the timing of conservation. However, there is still not enough international discussion and practice on conservation timing to find a reasonable solution. Based on the actual traffic conditions in our country, this study starts with the preventive maintenance of pavement. In order to solve the problems of aging rate, water seepage coefficient, duration of road surface roughness and pavement condition index (PCI) and so on, the article sets up the index system of functional prevention and curing for asphalt pavement to promote asphalt pavement The overall quality improvement.
