Abstract
Pervious Concrete Pavements (PCP) are considered a best management practice (BMP) by the United States Environmental Protection Agency (EPA) for stormwater runoff during rainfall events. PCPs provide an alternative to detention and retention ponds for engineers, which can ultimately reduce construction costs while improving the quality of stormwater runoff effluent through a three phase filtration system. Due to the high porosity typical of PCPs, there is an increased potential for void clogging during its lifespan due to soil, dust, and other particles produced by vehicular traffic and other environmental factors. This study evaluated the field performance of eight PCPs located moderately populated urban area by measuring the hydraulic conductivity and categorizing each as good, moderate, or severely clogged. A historical hydrologic analysis was conducted through the observation of the PCPs clogging over a period of five years. Further, an evaluation of suitable methods was performed to improve draining rate such that owners can extend the service life of PCPs. The cleaning methods investigated included sweeping, pressure washing, and vacuuming. Each method was evaluated through a statistical analysis to select the most desired technique for maintaining PCPs.
