排水降噪型沥青路面在养护工程中的应用研究

Research on the Application of Drainage Noise Reduction Asphalt Pavement in Maintenance Engineering

为研究排水降噪型沥青路面在养护工程中的应用,论文结合实际工程,介绍了排水降噪沥青路面的排水及降噪机理,重点研究了大孔隙排水降噪沥青混合料设计,并对其冻融劈裂下水稳定性、噪声水平和渗水性能等路用性能进行评价。

In order to study the application of drainage and noise reduction asphalt pavement in maintenance engineering,this paper introduces the drainage and noise reduction mechanism of the asphalt pavement combined with the actual project,focuses on the design oflarge pore noise reduction and drainage asphalt mixture,and evaluates its road performance such as freeze-thaw splitting water stability,noise level and water seepage performance.
