新时代公路沥青路面预防性养护技术及实践

Preventive Maintenance Technology and Practice for Highway Asphalt Pavement in the New Era

新时代,公路已成为国家经济发展的重要物流载体,路面养护是公路建设与维护至关重要的一环。沥青路面作为我国公路建设应用广泛的路面类型,具有较好的耐久性、平整度和舒适性,但随着路面的长时间使用,其各种性能持续下降,会出现龟裂、反射裂缝等问题。因此,有效应用预防性养护技术十分重要,文章结合实际案例,分析新时代公路沥青路面预防性养护特点、公路沥青路面预防性养护面临的问题,以及新时代公路沥青路面预防性养护技术及具体实践。

In the new era,highway has become an important logistics carrier for national economic development.Pavement maintenance is a crucial part of highway construction and maintenance.As a widely used pavement type in China's highway construction,asphalt pavement has good durability,smoothness and comfort.However,with the long-term use of the pavement,its various properties continue to decline,and problems such as map crack and reflection crack will occur.Therefore,it is very important to effectively apply preventive maintenance technology.Combined with practical cases,this paper analyzes the characteristics of preventive maintenance of highway asphalt pavement in the new era,the problems faced by preventive maintenance of highway asphalt pavement,and the preventive maintenance technology and specific practice of highway asphalt pavement in the new era.
