This article presents the behaviour of pervious concrete made with stone waste aggregate as replacement to natural granite aggregate in various proportions of 0%, 25%, 50%, 75% and 100% by volume of cast specimens. The study mainly focused to evaluate compressive strength, split tension strength and permeability. The split tensile strength was compared with ACI318-M-11 and GB50010-2002 codes and it is noticed that, the codes are underestimated the real strength of split tension. Hence a regression model was proposed to estimate the results and the model was checked with reliability based Integral Absolute Error (IAE). Micro structure analysis was performed for various mixes through Scanning Electron Microscopy (SEM) images.
