摘　　要：为了研究不同降雨强度下Ⅲ型全透式透水沥青路面的快速堵塞规律,设计了一种可以监测其堵塞状况的试验装置,采用控制变量法研究了雨强等5大因素对引起路面堵塞规律的影响.结果表明:堵塞行为的发生主要经历4个阶段,分别为急剧堵塞阶段、局部恢复阶段、渐进堵塞阶段和稳定出流阶段;偏粗型级配的路面抗堵塞能力要高于偏细型级配路面;全级配堵塞物最容易产生堵塞.该研究结果可为进一步研究和评价全透式透水沥青路面堵塞规律提供重要方法,并有助于透水沥青路面的优化设计.In order to research the Ⅲ type permeable asphalt pavement fast clogging rule under different rainfall intensity,a test device which can monitor its blockage condition is designed.The influence of 5 factors such as rain intensity on road blockage is studied by means of control variable method.The results show that the clogging behavior is mainly experienced in four stages,which are the quick clogging,the rapid plugging stage,the recovery stage,the progressive stage and the stable outflow stage.The anti-clogging capacity of the coarse-graded pavement is higher than that of the slabs.Full-graded clogging is the most likely to cause blockage.The research results can provide an important method for further study and evaluation of the plugging law of permeable asphalt pavement and help to optimize the design of permeable asphalt pavement.
