国内外排水沥青路面养护技术研究综述

Summary of Research on Maintenance Technology of Porous Asphalt Pavement at Home and Abroad

排水沥青路面是世界公认的安全、舒适、环保的功能路面,近年来在我国多个省份得到越来越多的应用。然而排水沥青路面在使用过程中容易出现孔隙堵塞、松散等病害,面临着养护问题。结合排水沥青路面的特点,从功能性养护、预防性养护、结构性养护修补和季节性冬季养护等方面,对国内外排水沥青路面养护技术进行调研分析,吸收先进成果和经验,为我国排水沥青路面养护提供借鉴和参考。

Porous asphalt pavement is recognized as a safe,comfortable and environmentally friendly functional road in the world.It has been applied more and more in many provinces of China in recent years.However,porous asphalt pavement is easy to be blocked,loose and so on in the use of porous asphalt pavement,and it is also faced with the maintenance of porous pavement with the extension of traffic time.Combining the characteristics of porous asphalt pavement,this paper investigates and analyzes the maintenance technology of porous asphalt pavement at home and abroad from functional maintenance,preventive maintenance,structural maintenance repair and seasonal winter maintenance,and draws on advanced achievements and experience.Improve the reference and reference for the maintenance of porous asphalt pavement in China.
