The National Highways Authority of India (NHAI) is expected to introduce a technology that could revolutionise road maintenance in the country. It will lead to creation of 'self-repairing or healing' roads. (Unsplash)
This technology will enable a road to 'repair' itself using a new type of asphalt, which will be infused with steel fibre along with bitumen. (Unsplash)
If a gap emerges on the road, the bitumen will spread to cover it and along with steel threads, fill the potholes. NHAI official say it will fix the persistent problem of potholes. (Unsplash)
The government is expected to undertake a cost-benefit analysis of the project before giving a go-ahead. NHAI is confident that the new technology will increase the lifespan of roads and minimise traffic disruption caused by potholes. (Unsplash)
Asphalt is a sustainable paving material used for constructing pavements and highways, along with airport runways, parking lots and driveways. (Unsplash)
But over long period of time, bitumen deteriorates, leading to erosion of the asphalt and the formation of cracks, which eventually evolve into hazardous potholes. The new technology aims to tackle this degradation. (Unsplash)
