India's Ministry of Road Transport and Highways drafts a policy to extend national highway lifespan by 20-25 years using 'white-topping'.
India's Ministry of Road Transport and Highways is drafting a new policy, seeking feedback, to extend the lifespan of national highways by 20-25 years using the 'white-topping' technique.
Focusing on rehabilitating asphalt pavement, this method covers existing asphalt with a layer of Portland cement concrete, reducing structural cracks, rutting, and potholes.
The policy aims to address the aging national highway network, which spans 146,000 km.
