Compared to conventional concrete, pervious concrete is simpler in constitution as it only contains paste and aggregate with monotonous size. During the mix design of pervious concrete, water to binder ratio (W/B ratio), binder or paste to aggregate ratios (B/A or P/A) and aggregate size and type need to be taken into consideration [8], [11], [12], [13].
