In India, Zydex Technologies is looking to build up to 20,000 km of moisture-resistant green roads by 2016 using its nanotechnology. Such roads need no maintenance for about 15 years. The company has already completed about 500 km of roads in India with Border Roads Organisation and other agencies, Zydex Industries said.
Zydex has already built such highways in US, Europe and Africa. The Gujarat-headquartered organisation has patented its nanotechnology which reduces water percolation into roads.
Use of this technology can help the government save Rs 7,200 crore per annum on bitumen only.
