摘要
介绍排水沥青路面的性能特点及存在的问题,指出大孔隙率和大粒径会导致混合料强度损失严重、耐久性差、施工困难等缺陷,并分析了问题产生的原因。应从混合料的原材料、施工工艺和质量控制3方面采取措施,使之既保持良好的使用性能,又具有足够的强度和耐久性。
This paper mainly introduces the performance characteristics of the porous asphalt pavement and its existing problems, and the reasons of the problems are analyzed. Because of the large porosity and particle, there are some defects about mixtures, such as strength loss, poor durability and construction difficulty. Several aspects of the improvement measures are given. To ensure the durability of porous asphalt pavement and keep good service performance and enough strength and durability, raw materials, construction technology and quality control should be taken into account.
