All roads in the national capital will be built up using international technology before the beginning of 2010 Commonwealth Games (CWG), Delhi Public Works Department (PWD) Minister Rajkumar Chauhan said Tuesday.
"Special attention is being paid to the roads which are around the places where the games would be held," Chauhan said, while inaugurating the work using "recycling and micro surfacing method" in south Delhi.
"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.
In the recycling method, about 70 per cent of the available material in the road is used and only about 30 per cent material is added to fill the gaps that occur 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.
