Potholes on Indian roads have always been a nuisance for drivers and passengers. The country has the second largest road network in the world, but it still suffers from potholes. In 2022, potholes caused more than 4,500 traffic accidents, resulting in approximately 1,800 deaths.
However, the National Highways Authority of India has come up with a smart solution to solve this problem and has brought a new technology that could bring a huge change in the road conditions in India. The use of self-healing materials for road construction is something the National Highways Authority of India hopes to achieve.

The technology promises to enable roads to repair themselves with the help of a unique asphalt. The new composite mix will then be infused with asphalt and steel fibers. What’s unique and interesting about this technology is that if a gap appears in the road, the asphalt actually spreads, covering the gap with steel wire to fill the pothole.
Work on the road to self-healing
National Highways Authority of India officials say the technology will actually solve the pothole problem. Potholes on roads cause a large number of deaths and accidents in India. However, it is currently unknown how long it will take asphalt to cover or repair gaps or potholes in the road. This asphalt repair technique actually works by integrating small pieces of steel wool into the composition of the asphalt. This is actually the binder component in asphalt. The heating of the steel fibers is promoted by an induction device during the initial process. This will melt and re-bond the asphalt.
