透水性沥青路面路用性能研究综述

摘要

近年来,透水性沥青路面在国内外得到了越来越多的应用.介绍了透水性沥青路面结构特点及原材料选择原则,重点介绍了国内外渗透系数的测试方法及目标空隙率的确定;同时,对透水性沥青路面降温、降噪、抗车辙等路用性能的研究现状做了详细的论述;并提出施工中存在的问题和建议,为透水性沥青路面的进一步推广提供参考价值.%In recent years,the permeable asphalt pavement has been wildly used at home and abroad.Its structure characteristics and raw materials selection principles are introduced in this paper and mainly described the test device of permeability coefficient and the relation between permeability coefficient and percentage of voids.Meanwhile,the road performance of asphalt pavement about cooling,noise reduction,anti-rutting and many aspects have been made a detailed elaboration,and also been put forward the existing problems and suggestions in the process of construction.It will be a reference for the further popularization of the permeable asphalt pavement.
