M6 rapid hardening concrete plan cuts disruption

NCE stock roads

Kier Highways claims motorists were saved almost an hour on their journey time after it carried out road repairs using a new weekend delivery model which incorporates rapid hardening concrete.

The team used concrete that reaches design strength in 18 hours rather than three days on the project. It meant the section of work could be completed over one weekend, enabling three lanes of the motorway to open in time for the Monday peak.

Overall Kier claims to have saved 35-days worth of lane closures, cutting the waiting time normally needed to filter three lanes down to two.

The works also saw 130m of expansion joints installed to provide additional strength and flexibility to the carriageway.

Kier Highways executive director Dave Wright said: “Having extensively trialled the product, we were trusted to use this new method and it has yielded excellent results, both in the efficiencies and savings, and in the quality of the solution.”

Highways England project manager Jessica Kenny said: “The material cures quicker and gains density as it hardens meaning that repair crews can work faster to carry out repairs without having to wait as long for it to harden.”
