NHAI inks MoU with IIT-Kharagpur to develop technology to construct maintenance free highways in India

The National Highways Authority of India (NHAI) has signed MOU with IIT-Kharagpur for research project to develop technology to construct long lasting maintenance free highways.

Under this MoU, IIT-Kharagpur will develop ‘Paneled Cement Concrete Pavements’ for highways. The duration of the research project is 3 years.

Background

  • Traditionally in India, the highways are paved with bituminous material produced from refineries.
  • However, these highways are prone to damage and need frequent maintenance due to adverse climatic conditions such as rain and hot weather prevailing in the country.
  • Therefore, to overcome this problem, the Union Road Transport and Highways Ministry recently had announced a policy for the construction of concrete pavements for all major highways due to their longevity and maintenance free life.

Paneled Concrete Pavement

  • The paneled concrete pavement can facilitate faster construction of highways at much cheaper cost by consuming fewer natural resources and thus promote Green Highways in the country.
  • This concrete will be laid on a lean concrete base which can provide long lasting maintenance free pavement at a cost on par with those of bituminous pavements.
