Chawathil First Nation Canada's first community

with self-healing road


 


Created in B.C., self-healing concrete can be used anywhere,

lasts longer, is a greener option 


​The future is coming, and it's arriving at Chawathil: the First Nation will be the

 first place in Canada to have a self-healing road.


"Chawathil is a very interesting community, very forward-thingking and modern-

thinking,"said Dr. Nemy Banthia, who's the research chair and University of

British Columbia (UBC) professor behind self-healing concrete. “They welcomed

us to bring this new technology into their community.

 

“And it’s very impactful technology,” Banthia continued. The First Nation will be

getting a “highly loaded parking lot and an approach road with lots and lots of

traffic.” Between the parking lot and the road, Banthia says there will be several

hundred square feet of the concrete installed in Chawathil.

 

Created in his IC-IMPACTS (India-Canada Centre for Innovative

Multidisciplinary Partnerships to Accelerate Community Transformation and

Sustainability) lab, a federal research initiative based at UBC, Banthia says the

self-healing road technology is a fibre-reinforced concrete that’s made through

combining tire fibres, plant-based cellulose fibres, and a nano-coated

manufactured fibre material: “It’s a hybrid system of (recycled and

manufactured) products,” the professor explained.

 

“We’ve already installed a self-healing road in the south of India, in a very small

village, but it has completely transformed the village,” Banthia said. Since the

road was installed in 2016, “it has required no maintenance … despite extreme

heat and monsoon rains.”

 

Self-healing concrete reduces crack formation by more than 90 per cent

compared to regular concrete, uses recycled products, “has the (smallest)

carbon footprint, and lasts at least five times longer. Concrete structures

naturally develop cracks over time, but these fibres are designed to bridge the

cracks as they form, enabling the structure to withstand extreme weather

conditions and last longer.


“It’s tremendously exciting to be able to use technology tested and proven

overseas to address infrastructure challenges (in) Canadian communities,”

Banthia added.


On Thursday, May 2, Banthia attended Chawathil First Nation for the

groundbreaking of their new self-healing roadway and parking lot.


“But we hope to scale this further, as we have a huge competitive advantage

(and a) really Canadian innovation,” Banthia said during a telephone interview.

“We’ll certainly watch how the pavement performs to ensure it holds up and

meets the requirements of (a Canadian) community” because the possibilities for

this product are nearly endless.


“It can be used everywhere. Everywhere concrete is used this can be used:

buildings, bridges, sidewalks. And it’s a basic material” that’s even earthquake

safe, Banthia said.​
