The permeable pavements are mainly constructed for the purpose of cultivating ground water and mainly applied on the sidewalk. It was admitted that permeability was effective for flood which increases rapidly in the city. And application on a heavy traffic road is also considered now in regarding to a recent law about control runoff. Therefore, test constructions are tried in various places. However, it is necessary to solve problems, such as durability, to apply permeable pavements to the roadway. Especially, aggregates of granular materials moves by infiltration of rain water and the quality have been changed. This paper verified the quality change of granular materials by the infiltration of rain water.
