Special concrete set to banish potholes
‘Self-healing’ surface repairs cracks automatically
THEY are the bane of every driver’s life and cost millions to repair but soon potholes could be a thing of the past.
Three universities have got together to develop a special type of self-healing concrete to repair cracks and crevices opened up by bad weather.
If the research is successful it could provide a better way to deal with bad roads.
Transport which looks for Bucks,
after the county’s roads, has said it is aware of the project and is ‘interested’ in anything that helps it maintain the roads.
Researchers the University of Bath, Cardiff University and the University of Cambridge created the concrete, which is full of bacteria hidden in tiny capsules.
When water seeps into cracks the bacteria bursts out and produces limestone, sealing the gap up before it becomes wider and a pothole.
The scientists have said it could remove the need
at for repairs altogether and reduce costs by half.
Pothole campaigner Alan Wallwork, of Lycrome Road, Chesham, said: “As with all new technology I’m a bit sceptical until it’s proven to work, but in principle this sounds like a good thing.
“My only thought when I heard about it is that this is based on concrete and our roads are mostly tarmac around here, so I’d wonder how this would work. I agree with TfB absolutely that they need to look into it first and see if it could provide a solution Buckinghamshire.”
The spokesman for Transport for Bucks Dan Elworthy said: “We are aware of the research being carried out and are interested in any initiative or innovation which can bring efficiency or added effectiveness to our maintenance practices. We will therefore investigate the findings of the research and any practical application which can be adopted.”
