Restoration of infiltration capacity of permeable pavers

This study investigates the infiltration capacity of UNI Eco-Stone © permeable pavers, located at the University of Guelph. The objectives of this research were to determine how infiltration capacity, volatile organic matter, heavy metal concentration and particle size analysis of the external drainage cell material vary with average daily traffic use and surface ponding. Using a rainfall infiltrometer, 110 test plots at the University of Guelph were subjected to 420 tests comprising two simulated rainfall events of known intensity and duration. Data collected during the second rainfall was used to calculate effective infiltration capacity.; Preliminary results yielded quite different results for infiltration capacity and particle size analysis of the external drainage cell material for the different average daily traffic uses. To a lesser degree, a relationship for the amount of volatile organic carbon and average daily traffic use was also developed. A definitive relationship for the heavy metal concentration and the average daily traffic use could not be developed. Recommendations are made concerning the type and frequency of maintenance for, and the design of, permeable pavement installations.*; *This dissertation includes a CD that is compound (contains both a paper copy and a CD as part of the dissertation).
