Recommendations of National Get-together on Road Research and Its Utilization (NGT 2012)
CSIR-Central Road Research Institute, organised a National Get-together on Road Research and its Utilization (NGT-2012) at New Delhi on March 1-2, 2012 to provide excellent forum for highway engineering fraternity – researchers, experts, technocrats, academicians, consultants and consulting firms, manufacturers associated with road developments in our country to deliberate on emerging issues of roads and road transportation for sustainable infrastructure development in the country. The Get-Together was sponsored by 15 organisations and was attended by more than 400 delegates representing DDA, NHAI, PWDs, various R&D and academic Institutions. The Get-Together was inaugurated by Sh.C. Kandasamy, Director-General (RD), MORTH, while Lt. Gen.R.Ravi Shankar, PVSM, VSM, DG(BRO) was Guest of Honour. The two-day meet comprised of seven Technical sessions which included Panel discussions and presentation on important themes viz., Pavement Engineering & Materials, Hill Roads and Landslide Mitigation, Urban Transportation, Road Safety & Environmental issues. The interactions resulted in a number of priority areas of R&D pertaining to road and road transportation. A copy of the gist of key issues / recommendations/ R&D Priority areas which emerged during various sessions are given below:
