New resurfacing technology used for first time in the UK

Contractor A-one+ is resurfacing over 1.6km of the A1 at Brownieside in Northumberland using cold paving technology — a first for the UK.

The company is using a bespoke Wirtgen CR 3200 machine to recycle the underlying layers of the road. The old surface material is churning up with new material within the machine, before laying it down immediately on the road behind.

With the new method, 500 to 1,000t of road surface can be laid per hour — a significant increase when compared with the 100t per hour of conventional techniques.

Additionally, it reduces the quarried stone used by 75%, the waste taken to landfill by 66%, and requires 70% fewer lorry trips to and from site.

Steve Bishop, Highways England’s project manager, said: “This new technology is brilliant news for the thousands of drivers that use motorways and major A roads in the North East, who will benefit from smoother and safer journeys.

“The road surface is designed to last for at least 10 years, meaning that we shouldn’t need to go back to carry out further repairs any time soon meaning less disruption for drivers.

“This is the first machine of its type in the UK but the process is already successfully used in the USA, France and China. We are always working with our partners to trial new technologies that will help us to minimise disruption to drivers while we carry out essential road maintenance.”

Work started at the beginning of August and is now finished.
