摘要
随着我国经济快速发展,公路里程逐年递增,在保证基本路用性能的前提下,路面的功能性与耐久性的提高也尤为重要。多孔沥青路面具有优良的降噪性能、抗滑性能和排水性能,是近年来应用较为广泛的典型路面类型之一;但同时该路面在应用过程中,也存在一些问题,如耐久性较差、易出现水稳定性不足等病害。本文对比了国内外在多孔沥青混合料配合比设计上的差异,总结了国内多孔沥青路面的应用现状,分析了该路面常见的病害类型及成因,并给出了相应的改善措施。
With the rapid development of China's economy,the highway mileage is increasing year by year.Based on the premise of ensuring the basic road performance,the improvement of pavement's functionality and durability is particularly important.Porous asphalt pavement has excellent noise reduction performance,skid resistance and drainage performance,which is one of the typical pavement types widely used in recent years.But at the same time,there are some problems in the application process of the pavement,such as poor durability,easy to appear insufficient water stability and other diseases.This paper compares the differences of porous asphalt mixture design at home and abroad,summarizes the application status of porous asphalt pavement in China,analyzes the common disease types and causes of the pavement,and gives the corresponding improvement measures.
