Use of pervious concrete for pavement construction provides benefits such as reducing the stormwater run-off and recharging the ground water. This paper discusses the results of an experimental investigation into the effect of pore structure clogging and compaction on the water permeability of pervious concrete. The water permeability of pervious concrete was studied under falling head. The results showed that the clayey materials presence in the percolating water had seriously reduced the water permeability of pervious concrete. High-pressure water cleaning was found to partially recover the water permeability of pervious concrete. Since compaction causes pore structure modification, it should not be used with pervious concrete to ensure high water permeability of pervious concrete.
