Nemkumar Banthia, an Indian professor in Canada has come up with a brilliant technology of self-repairing roads

Almost everyone is familiar with the poor quality of roads in India. No matter how many times they are repaired, these roads easily lead to self-destruction with just one monsoon. Well, here’s a good news. An alumni of IIT, who is currently a professor in Canada has invented a fantastic way which will allow the roads to mend themselves without any added cost.
He created these self-repairing roads with the use of highly advanced technology and materials. These roads tend to have a good longevity, sustainability and are cost effective too.
Nemkumar Banthia is a teacher in the department of civil engineering, University of British Columbia (UBC). He hails from Nagpur, India. After he shifted to Canada 34 years back, he started searching for better roads. Banthia started with his project of constructing such advanced technology roads in a village about 90 km away from Bengaluru. It was seen a tool to improve the life of the villagers.
Banthia also worked with the IC-IMPACTS, Canada-India Research Center of Excellence as a scientific director where he found this new life giving technology for Indian roads. The roads are less costly and also economic friendly. These roads use 60 percent fly ash instead of cement thus preventing common carbon footprints whereas use of cement release greenhouses gases.
The roads were constructed last winter in the village and have successfully sustained all four seasons. They are about 60 percent less thicker as compared to the common Indian roads thus reducing production cost and raw materials. Also, the roads contain highly strong concrete equipped with fiber reinforcement having nano-coating. This enables the roads to absorb water and stay hydrated thus allowing them to self heal.
Banthia says, “These are fibres which have a hydrophilic nano-coating on them. Hydrophilia means they attract water and this water then becomes available for crack healing. Every time you have a crack, you always have unhydrated cement and this water is now giving it the hydration capability, producing further silicates which actually closes the crack in time”.
According to Banthia, the roads can last for up to 15 years which is far more than the lifespan of typical Indian roads. The initial cost is 30 percent cheaper hence money is also saved. Currently, the projected is destined to cover 2.4 million km roads in rural places in India. Afterwards, the project will commence to larger states starting with Madhya Pradesh and Haryana.
He says that the technology is not just restricted to India and is expected to expand to parts of Canada as well.
