The aim of this study is to evaluate the effects of aggregate system on pervious concrete. The ever-rapid growing of urbanization and the increasing threat of global warming have likely to cause the increase in runoff or precipitation in various regions. For many years, pervious concrete has been making a significant contribution to sustainable urban drainage system. Besides improving environmental condition, pervious concrete can help in minimizing risk of flooding, reducing runoffs and peak flows, improving the precipitation load on overstressed drainage system, recharging ground water and can improve water quality by capturing pollutants. This study is conducted by doing lab works that include sieving, mixing, compacting, casting and testing of hardened concrete at 7-day and 28-day. This study suggested that the usage of higher amount of smaller aggregate on pervious concrete had resulted in higher compressive strength than the one's with less amount of smaller aggregate. This study also suggested, the usage of higher amount of bigger aggregate on pervious concrete had resulted in higher value of permeability constant, K (mm/s) than the one's with less amount of bigger aggregate.
