沥青路面是一种相对特殊的公路路面形式,如养护工作无法有效进行,则不但会缩短道路的寿命,同时还会对道路的安全通行造成严重的不良影响。实践证明,做好沥青路面的养护工作有助于改善道路行驶的舒适度及提高车辆的通行效率。为了能够有效养护沥青路面,本文对沥青路面的养护现状进行了分析,并在此基础上探讨了常见的沥青路面养护技术,包括路面裂缝填封技术、雾状封层和还原剂封层养护技术、碎石封层养护技术、薄层罩面养护技术、微表封层养护技术、坑洞修补术、沥青再生技术以及开槽修补法。
Asphalt pavement is a relatively special form of highway pavement. If the maintenance work can not be effectively carried out, not only will it shorten the life of the road, but also cause serious adverse impacts on the safe passage of the road. Practice has proved that doing a good job of maintenance of asphalt pavement helps to improve the road driving comfort and improve traffic efficiency. In order to effectively maintain asphalt pavement, this paper analyzes the status quo of asphalt pavement maintenance, and on this basis, discusses the common asphalt pavement maintenance technology, including pavement crack sealing technology, fog sealing layer and reducing agent seal maintenance technology , Gravel seal maintenance technology, thin layer cover maintenance technology, micro-watch seal layer conservation technology, pit repair, asphalt recycling technology and grooving repair method.
