As a mean to deal with urban rainfall and water disaster, the permeable pavement is more widely used. The permeability and effect of clogging are essential inputs in hydrologic design, but there is no well developed standard yet to evaluate the permeability. This study aims at developing test equipment and procedure to evaluate permeability of unclogged and clogged permeable pavements. Two types pervious concretes, with different sizes of aggregate in mixture but with the same porosity, were produced and tested by the equipment developed. It is found that the discharge velocity and hydraulic gradient have nonlinear relationships. More particles were clogged in the concrete with larger pore, but the permeability decreased more steeply with increasing clogging particles in the concrete with smaller pore. The results shown here are, however, based on the specific materials and cases tested, and therefore it is necessary to investigate further in order to come up with more general conclusions.
