Now a days the urban population is increasing day by day and with that increase needs the raise in concrete jungles where almost all parts of city is covered with impermeable concrete. Due to this the recharge of ground water is decreases and in rainy seasons the water stored on the roads create nuisance to the public.In the recent past we have observed the destruction caused by
the nature to a renowned city Chennai. The answer to the above problem is pervious concrete. It consists of coarse aggregate,
cement, and water. Pervious concrete is a zero slump, open graded and light weight concrete. It is also known as “no fines concrete”. It is having a high void content of about 30%. Due to this reduce the runoff to the drainage systems. Environmental protection agency (EPA) recognized that pervious concrete is a green building material for providing pollution control and storm water management. It is used for various purposes like for footpath, pavement, street road etc,.by evaluating compressive strength, split tensile strength and permeability. The aim of this project is to design and study the effects of aggregate gradations on the permeability of pervious concrete
