Abstract: On account of urbanization, impervious coverage has increased rapidly and rainfall pattern varied much due to the global weather change. So, peak flood discharge arose more easily and concentration time of stormwater reduced nowadays. In order to solve these kinds of problems, Low Impact Development (LID) techniques such as permeable pavement have been suggested as one of the solutions and recently more interested. To evaluate decrease of surface infiltration rate of porous asphalt pavement systems over time, surface infiltration rate of two porous asphalt road testbeds which have different layer systems was investigated by using ASTM C 1701 standard test method for about one year. The differences of pavement understructure were judged to have no influence on surface infiltration rate. During the test period, average surface infiltration rate decreased from 0.59 to 0.19 mm/s.
