Pervious concrete texture analysis for infiltration rate evaluation

Abstract

Pervious concrete contains voids from 15% to 30% so that water could penetrate thru it in order to reduce surface runoff from percolates on top of the surface or pavement. This study is carried out to determine the suitable type of texture that could maximize the infiltration rate based on the proportion and type of material being used. Besides, the uncertainty of concrete preciousness also could be determined to evaluate the infiltration rate value when using pervious concrete on soil. Also, Monte Carlo Simulation is applied. The highest infiltration rate for pervious concrete sample is 1.24×10 5 mm/hour, with the maximum probability density function of infiltration at 207.18 cm/min (22.59%). The lowest infiltration rate for one of the concrete sample is 8.99×10 5 mm/hour, with the minimum probability density function of infiltration rate at 151.18 cm/min (21.31%).
