ABSTRACT
Considering the Increased rain fall in recent years due to the effect of climate change is leading to increase in surface run-off and flooding in urban regions, while impervious concrete or asphalt covering of urban lands curtail groundwater recharge and causes water logging. But by allowing surface water to seep downward through the porous structure of the pavements, pervious concrete pavements, also known as porous concrete pavement, have the potential to function as a Sustainable Urban Drainage System (SUDS), reducing the risk of flooding, replenishing groundwater, lowering runoff and peak flows, and enhancing water quality by absorbing pollutants. This study is about using pervious concrete pavement to reduce flooding and manage storm water. The test was carried out by using coarse aggregate of different sizes (10mm, 14mm, 19mm) and three different mix ratios (1:3, 1:4, 1:5), to determine the most suitable design. Cube of size 100mm x 100mm x 100mmwas prepared for this design. The water-cement ratio was kept at different ratios 0.33, to 0.37 The result obtained shows significant difference between all mixes, however, on the 28th day, the mix proportions with aggregates size (1:4 and 14mm respectively) gives the most suitable compressive strength and porosity of 18.25N/ 𝑚𝑚² and 21.7% respectively when compared to mixes with other aggregates size. The pervious concrete can mainly be applied to parking areas, sidewalks & pathways, residential roads, alleys and driveways, shoulders & medians, bridges, swimming pool decks, slope stabilization, footpaths.
