Rajkumar Chauhan, the Delhi Public Works Department (PWD) Minister, told on Tuesday that the roads of Delhi will be given a complete makeover using international technology before the 2010 Commonwealth Games kick off.
Chauhan, who was inaugurating the upgrading works, which is being done using "recycling and micro surfacing method" in South Delhi mentioned that "Special attention is being paid to the roads which are around the places where the games would be held”.
"A total of 242 km of Delhi roads are being built up with the new technique, which will cost around Rs.2 billion (Rs.200 crore)," he added. The work will be finished by June 2010.
Under this method, 70% of the existing material is reused whereas the 30% is added to repair the gaps that have come up due to wear and tear and atmospheric action on the road over a period of time.
"It is purely an eco-friendly technique and consumes less material. The thickness raised is only 10 to 15 mm. Life of such treated roads is claimed to be 5 to 7 years," Chauhan said, according to an official statement here.
In micro surfacing technique, cold bitumen emulsion is mixed with fine stone aggregates whose mix is then spread over minor cracks in the road surface.
"Life of the road by this method is increased to 2-3 years. In this technology, the thickness added to the existing surface is almost nil. The roads built by micro surfacing will be waterproof," the statement cited the minister as saying.
