由防滑降噪沥青混凝料组成的路面具有良好的抗滑、排水和降噪功能,在城市道路建设中扮演着重要角色,然而目前对该材料透水性的相关研究还不够完善。本文基于防滑降噪沥青路面空隙率、连通空隙率以及渗水系数3个指标,运用MATLAB软件,对路面结构的透水性能进行评价分析。结果表明:防滑降噪沥青路面良好的排水性能主要源于结构内部的大量孔隙,连通空隙率可作为该类路面渗水系数控制指标;同时,本文采用的与常水头渗透仪装置配套的防滑降噪沥青路面透水性能评价软件计算结果准确可靠,可在实际工程中运用。

The pavement composed of anti-skid and noise reduction asphalt mixturet has good anti-skid,drainage and noise reduction functions,and plays an important role in the construction of urban roads.However,the current research on the water permeability of this material is not perfect.Based on the three indexes of anti-skid and noise reduction asphalt pavement porosity,connected porosity and water permeability coefficient,MATLAB software is used to evaluate and analyze the water permeability of the pavement structure.The results show that the good drainage performance of the anti-skid and noise redu...
