Study of effective laying pattern of permeable interlocking concrete paver for storm-water management

Abstract

This study determined the skid resistance and runoff infiltration rate of different laying patterns of PICP, namely stretcher bond and herringbone patterns. The dimensions of PICP block are 10.3 cm (height) × 12.5 cm (width) × 25 cm (length) and arranged for a total coverage area of 1.8 m2. Pendulum skid resistance tester and ring method were used to determine the skid resistant and runoff infiltration rate, respectively. The herringbone pattern showed higher skid resistant value in either dry or wet condition compared to stretcher bone pattern. Herringbone pattern exhibited infiltration rate of 21450.7 mm/hr while stretcher bond pattern only has an infiltration rate of 18516 mm/hr. It is observed that herringbone pattern performed better than the stretcher pattern in term of storm-water management.
