Water reaches earth in the form of rain fall. The use of pavement materials like Bitumen, Asphalt concrete seals the soil surface which restricts the rain water from infiltration & natural ground recharge. The construction of impervious pavements initiates a chain of events which results in change in urban environment thus causing an imbalance in ecosystem. Pervious concrete which is referred as enhancing porous concrete gap graded concrete or no fine concrete is a step forwards minimizing urban flooding. The pervious concrete mix is prepared using aggregates conforming to IS- 383, cement, polyvinyll alcohol (PVA) & silica fume, and zeolite as admixture. Zeolite, silica fumes is used for replacing cement in various percentages. The cement paste binds the aggregates leaving voids, these voids make it possible for rain water to drain out from pavement surface. As the water flows down to underground surface recharges the ground water for sustainable development. In this project the parameters such as compressive strength, flexural strength, drainage conditions of various mix proportions of pervious pavement layer will be studied.
