Spe­cial con­crete set to ban­ish pot­holes

‘Self-heal­ing’ sur­face re­pairs cracks au­to­mat­i­cally

Buckinghamshire Advertiser - - NEWS - By Jo-Anne Rowney jo-anne.rowney@trin­i­tymir­ror.com

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.”
