基于其自身的结构特征,排水性沥青混凝土路面具有良好的排水、防滑、降噪、消雾等特性,因而在许多地区进行试点推广,同时也得到国内外专家学者的广泛关注。文中重点分析了排水性沥青混合料的构造特点、排水机理、孔隙率、渗透性、结构耐久性及降噪性,对强度不足、承载能力下降和孔隙阻塞等方面存在的问题进行归纳总结,并初步提出了解决方案。最后探讨了排水性沥青混凝土路面未来的发展前景。
Due to its own structural characteristics, drainage asphalt concrete pavement has good drainage, anti-skid, noise reduction, anti-fogging and other characteristics. Therefore, it has been piloted in many areas and attracted wide attention from domestic and foreign experts and scholars. The paper mainly analyzes the structural characteristics, drainage mechanism, porosity, permeability, structural durability and noise reduction of drainage asphalt mixture, summarizes the existing problems in the aspects of lack of strength, bearing capacity and pore blocking Initially proposed solutions. Finally, the future development of drainage asphalt concrete pavement is discussed.
