混凝土路面砖路面排水性能受多种因素的影响，如路面坡度、渗水性能等。着眼于混凝土路面砖路面的渗水性能，假定其仅与路面缝隙比和缝隙渗透能力有关，并通过实测分析了使用龄期对路面渗水性能的影响。对某地区14处使用龄期不等的混凝土路面砖路面透水性进行了测试，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，则路面的透水性越差，并随使用龄期几乎呈指数形式下降；同时，也对这种现象进行了深入分析，发现使用龄期越久，缝隙中所含小颗粒物质越多，这种原因是造成缝隙渗水能力下降的主要原因。试验中也发现，植被对保持土壤疏松、增强土壤的渗水性能有着重要影响。

Drainage performance of the pavement is impacted by many factors,such as the slope,pavement age and so on. It focused on the infiltration performance of the concrete block pavement and conducted anexperiment about the influence of the pavement age on it. Therefore,14 different aged concrete blocks pavement were selected as our objects of research,of which,the youngest is cero and the oldest is 25 years old. Results show that,with longer usage time,the infiltration performance decreases sharply,almost exponentially. In addition,it conducted a further research on this phenomenon and found that with longer pavement age,there would be more tiny parti-cles in the soil. And this is the very reason resulting in the phenomenon. What is more,vegetation also affects this performance greatly in practice.
