Design, construction and performance of porous asphalt pavement for rainwater harvesting

Multi-storied commercial and residential buildings, which significantly increase the demand for water supply, are increasingly being constructed in urban India. In many states of India, such as Bihar, Delhi, Gujarat, Haryana, Punjab, Rajasthan and Tamilnadu, the ground water is plunging at an alarming rate. Responsible town planners, architects and civil engineers must be proactive and integrate rainwater harvesting techniques in the design of all types of buildings, parking lots and low-trafficked roads/streets. For example, Public Works Department (Buildings and Roads) engineers can integrate government buildings with porous asphalt parking lots. This would recharge the ground water in over-exploited/critical areas of India. The revolutionary technology represented in this paper addresses that very need. The porous asphalt pavement which can be used for parking lots or low-traffic roads/streets works as follows: the top 75 mm asphalt layer is specially designed to make it porous. Rainwater goes through it rapidly without any ponding. The water is then stored in an underlying open-graded stone bed, which is about 225 mm thick. From there, water percolates slowly into the underlying soil. The porous parking lot or street can be integrated with a roof rainwater harvesting system in the buildings adjacent to it by diverting the roof water to the stone bed. Recently, ,the Jaipur Development Authority has constructed the first ever porous asphalt parking lot in India. This paper gives the details of its design, construction and performance.
