Now Waste Plastic to Strengthen Roads

Government of Delhi started its initiative for a cleaner environment banning plastic bags some time before, now in a new move the waste plastic will be used to build roads in Delhi and NCR. Read on...

To ensure a smooth ride during the Commonwealth Games, Public Works Department (PWD) is going to use waste plastic technology to resurface a total of 242-km road length in the city at a cost of around Rs 250 crore. The new technology will ensure longevity of the roads.

Minister, PWD, Rajkumar Chauhan on Friday inaugurated the resurfacing work of roads in south Delhi. He said: "Special attention is being paid to roads leading to Games venues. All Delhi roads will be built using international technology.'' The waste plastic technology involves mixing waste plastic and bitumen. This ensures greater longevity and flexibility of roads.

Work on strengthening the roads using waste plastic and micro-surfacing technology has begun on 71-km road length under PWD in south Delhi and 32-km of roads in east Delhi. The technology has already been used to resurface around 60km of the roads in Delhi. This technology will help take care of plastic waste in the city.

Resurfacing of key roads in south Delhi using waste plastic technology will cost around Rs 33.22 crore. These roads include Airport area, Rama Road, Aruna Asaf Ali Marg, IGP Slip Road, Bhairon Marg, Okhla Estate Marg no-13, Bhakti Vedanta Marg, Anuvrat Marg, etc. According to PWD officials, the resurfacing of roads will be completed by June 2010.

"Plastic technology is eco-friendly and consumes less material. The thickness is raised by only 10-15mm and such roads would last up to seven years,'' added Chauhan.

Said PWD secretary K K Sharma: "The bitumen melts at higher temperatures during summer and when mixed with plastic it adds to the flexibility and durability of roads.''

Besides waste plastic technology, PWD is also using in-situ technology to resurface roads and a 100 crore project has already been approved by the government. Under in-situ technology, raw material on the surface of the road is removed, heated and after adding some amount of new material it is used again for re-laying of road. This helps in maintaining the level of the road and is eco-friendly as well.
