Currently, there does not exist any established test method to evaluate the long-term performance of a porous asphalt pavement against clogging, with or without maintenance cleaning. This study proposes a laboratory test method to bridge this gap. The test method consisted of three main procedures: (i) A procedure to introduce clogging materials into a test specimen, (ii) a procedure to measure the permeability coefficient of the specimen, and (iii) a de-clogging cleaning procedure simulating high-pressure washing. Three porous asphalt mixtures were studied. The test results showed that mixtures with a higher initial porosity required less maintenance effort in terms of the frequency of cleaning, achieved higher cleaning effectiveness in terms of the overall pavement service performance, and had longer service life. A higher cleaning frequency having cleaning activated sooner would produce better overall pavement permeability performance over the entire pavement service life.

目前，不存在任何既定的测试方法来评估多孔沥青路面的长期抗堵塞性能，无论是否进行维护清洁。本研究提出了一种实验室测试方法来弥补这一差距。该测试方法由三个主要程序组成：(i) 将堵塞材料引入测试样品的程序，(ii) 测量样品渗透系数的程序，以及 (iii) 模拟高强度的除堵塞清洁程序。压力洗涤。研究了三种多孔沥青混合物。测试结果表明，具有较高初始孔隙率的混合物在清洁频率方面需要较少的维护工作，在整体路面使用性能方面实现更高的清洁效果，并具有更长的使用寿命。
