雷诺锋沥青路面养护技术作为一种新型预防性养护技术,具有加强原路面骨料、恢复沥青质性能、降低路面渗水、延长路面使用寿命等特点,在国外已开始了大规模应用,并获得了良好的评价。我国于2011年9月首次在杭州湾跨海大桥南岸连接线上应用该项技术,本文通过对雷诺锋粘结剂材料组成进行介绍,提出了雷诺锋沥青路面材料的技术标准,并通过路面渗水系数试验以及延长磨损试验对雷诺锋沥青路面的路用性能进行了研究,为该技术今后在国内的应用提供依据。
As a new preventive maintenance technology, Renault front asphalt pavement maintenance technology has the characteristics of strengthening the original pavement aggregate, recovering the asphaltene properties, reducing the water seepage of the pavement and prolonging the service life of the pavement, etc., and has begun to be applied on a large scale in foreign countries and obtained Good evaluation. China applied this technology for the first time on the south bank of Hangzhou Bay Bridge in September 2011. This paper presents the technical specifications of Renault front asphalt pavement material by introducing the composition of Renault front binder and seepage through the road Coefficient test and extended wear test on the road performance Renault front asphalt pavement performance for the technology in the future to provide the basis for the application.
