Abstract

Civil Engineering Permeable Interlocking Concrete Pavers (PICP) infiltration stormewater polllution sediment clogging
Clogging of permeable interlocking concrete pavements (PICP) due to the sediment contained in stormwater runoff has been shown to significantly reduce their infiltration capacity over time. Numerous studies have used laboratory-based PICP models and synthetic stormwater in an attempt to replicate and predict the clogging processes that occur in PICP field installations. A variety of sediment types and sizes, and stormwater application rates have been used in these studies with mixed results. The current study investigated the effects that varying sediment types, varying particle size distributions and varying testing durations had on clogging of PICP models. Eighteen speciallyconstructed PICP models were tested in the laboratory using the accelerated semi-synthetic stormwater simulation technique. The study results have revealed new insights into the reliability and validity of laboratory-based PICP clogging testing results and how the results should be viewed.
