摘　　要：假定混凝土路面砖路面的渗水性能仅与路面缝隙比和缝隙渗透能力有关,通过实测分析使用龄期对路面渗水性能的影响,选择某地区14处使用龄期不等的混凝土路面砖测试路面透水性,其中最短使用龄期为新铺路面,最长为使用25年路面。结果表明:使用龄期越久,缝隙中所含小颗粒物质越多,路面的透水性越差,并随使用龄期几乎呈指数形式下降。Given that the water permeability of concrete brick pavement is only related to the pavement crevice ratio and crevice permeability, this paper measured and analyzed the influence of service age on the water permeability of pavement. The water permeability of concrete pavement bricks of different service ages was tested. 14 pieces of concrete pavements brick of different service ages, from less than 1 year to 25 years, were tested. It was found that the older service age of pavement is, the more fine granular substances there are in the crevice and the poorer water permeability of the pavement, and the water permeability of the pavement drops after its service age in an exponential form.
