Highways Authority Plans to Construct Self-Healing Roads in India: Report

In case of any gaps on the road, the bitumen will spread out to cover it and, with the help of steel threads, fill up the potholes. NHAI officials believe that this innovation will help address the persistent issue of potholes, which are a major cause of road accidents and fatalities in India.

However, it is currently unclear how long it will take for the asphalt to cover and repair a pothole or gap on the road.

“We are exploring creative and unconventional methods to enhance durability and tackle the problem of potholes,” a senior government official stated, as reported by the Economic Times.

Before moving forward with the project, the government will conduct a cost-benefit analysis. NHAI is confident that this new technology will extend the lifespan of roads and reduce traffic disruptions caused by potholes.

Asphalt is a sustainable paving material commonly used in the construction of pavements, highways, airport runways, parking lots, and driveways. It accelerates construction, is eco-friendly, and offers a smooth and quiet driving experience.

It is created by mixing aggregates, binder, and filler. Aggregates are combined with bitumen to produce a strong and dependable mixture. Specialized trucks transport the hot asphalt mixture to the desired location, where it is spread and compacted using heavy machinery.

Over time, bitumen deteriorates, causing erosion of the asphalt and the development of cracks that eventually turn into dangerous potholes. The new technology aims to combat this deterioration.

NHAI is a government agency tasked with the construction and maintenance of the national highway network in India.
