摘　　要：精细磨耗层是由碎石封层演变而来的一种新型沥青路面预防性养护技术,文章介绍了精细磨耗层的适用范围、技术特点及工艺流程,结合南通市2021年道路大中修工程实例,对道路养护后的路面渗水系数、抗滑系数等指标进行检测,各指标均达到规范要求,有效提升了路面综合性能,预养护效果显著。精细磨耗层不仅施工成本低,而且施工速度快。精细磨耗层是一种超薄封层工艺,适用于城市道路的预防性养护。The fine wear layer is an innovative preventive maintenance technique for asphalt pavement,derived from the crushed stone seal layer.This paper provides an overview of the fine wear layer,including its application scope,technical characteristics,and process flow.Drawing upon the large and medium road repair project in Nantong City in 2021 as an example,the study evaluates the road surface seepage coefficient,anti-skid coefficient,and other performance indicators after the implementation of the fine wear layer.Results demonstrate that all indicators meet the required specifications,effectively enhancing the overall performance of the road surface.The fine wear layer offers advantages such as low construction cost and rapid construction speed.It serves as an ultra-thin sealing layer process suitable for preventive maintenance of urban roads.
