This study describes field investigations designed to compare the infiltration capacities of 55 permeable pavement systems installed in the Netherlands and in Australia. The ages of the pavements varied from 1 to 12 years. Using infiltrometer testing, the performance of the pavements has been compared in terms of their ability to infiltrate a three month average recurrence interval storm event in the case of the Australian pavements or the minimum specification for European infiltration capacities of 97.2 mm/h for the Dutch pavements. Many of the tested pavements broadly follow a hypothetical decay curve of infiltration rate with age of pavement. However, these are clustered into two distinct groups (Dutch and Australian) with the older Australian pavements appearing to maintain higher infiltration rates relative to their age. The study has shown that the performance of the clogged permeable pavement systems was still generally acceptable, even after many years in service.
