UBC prof paves way for nano-fibre roads that repair themselves

Metro News reported on a self-repairing road project in rural India spearheaded by Nemkumar Banthia, a UBC civil engineering professor.

Banthia explained the intricacies of coated nano-fibres in the road.

“This coating creates a higher humidity environment,” Banthia said. “Cement hydrates when the humidity goes up, so if a crack is created these fibres secrete a nano-material to release humidity — which allows the concrete to close those cracks.”

Banthia was also interviewed by the Chinese news agency Xinhua.
