CONSTRUCTION AND PERFORMANCE OF POROUS ASPHALT PAVEMENT FOR RAINWATER HARVESTING

Porous asphalt pavements allow for land development plans that are more thoughtful, harmonious with natural processes, and sustainable. They conserve water, reduce runoff, promote infiltration which cleanses stormwater, replenish aquifers, and protect streams. Rainwater & storm water Harvesting being an essential need of the future, it can be achieved not only through roofs but also through concrete and asphalt roads. The research has focused on improving quality and quantity of ground water. Study investigates performance of aggregates and porous asphalt used in projects, such as properties of aggregates like impact value, crushing value, specific gravity, abrasion test. Tests performance on porous asphalt includes ductility test, fire point test and penetration test. This paper summarizes the construction and performance of porous asphalt pavements. It includes comparison study of porous asphalt pavement and convectional asphalt pavement.
