The Minister said construction materials which behave normal in plain areas may not be conducive in the extreme cold climate of high altitude areas.
He stressed the need for the application of nanotechnology which will be of great use in soil stabilisation, being a pre-requisite for construction of roads and tunnels in such areas.
He was addressing the inaugural function of a two-day 'International Seminar on New Construction Materials Techniques and Design in Bridge, Tunnel and Road Construction Suitable for Infrastructure Development in Inaccessible Border Area' here.
The seminar is being organised by BRO in partnership with Indian Institution of Bridge Engineers, Delhi State Centre (IIBE, DSC) and in collaboration with Ministry of Road Transport and Highways, National Highways Authority of India, Central Public Works Department and Ministry of Railways.
Speaking on the occasion the Director General Border Roads Lt Gen R M Mittal said road construction has become very vital in infrastructure development of the country.
