Pothole repair machine fixing Nottinghamshire’s roads


A new machine which can fill potholes quicker and more permanently than before will be brought onto the roads in Nottinghamshire after a trial scheme proved successful.

It is hoped the new techniques will stop potholes from having to be repeatedly filled, saving money in the long-run.

In February, Nottinghamshire County Council approved £1.75 million for the project, which also includes two new techniques for filling pot holes.

The new technology has now been tested throughout the summer, and has received a seal of approval from the council.

The machine, known as the Road Master, is now expected to be fully operational by spring next year.

It comes after a particularly harsh winter last year meant 115,000 potholes had to be filled – which the council said led to concerns about the sustainability of the approach.

Already this year, 70,000 pot holes have been filled.

Councillor John Cottee, head of the county’s highways committee, who also represents Keyworth for the Conservatives, said: “We’ve been delighted with the positive impact that the new equipment has had on our repairs so far, providing us with another tool to repair and prevent road surface deterioration in the county and significantly improving productivity.

“Road repairs and resurfacing is one of our top priorities and this £1.75m is a long-term investment to save more money further down the line whilst improving the quality of road repairs, increasing productivity and extending the life expectancy of our roads and is another example of our continuing investment in the network.

“The new Roadmaster we have on order is due to be with us by the spring. It has a higher specification than the machine we’re currently using, including an integrated roller to provide an even better finish.”

One of two new techniques highways workers will now be able to use is called spray injection chip patching, which will be made possible by the new machine.

First, a high-pressure blower will blast the area to get rid of dust and debris. A sticky seal is then sprayed into the area, before new bitumen and aggregate is sprayed into the pothole.

Once that is done, the area around the defect is sprayed to leave a larger, square patch which is designed to prevent the pothole opening up again in the future.

Dry aggregate is then sprayed onto the new patch, meaning cars can drive over the repair straight away.

Another new system, known as mechanised patching, will also be brought in to deal with more major and structural damage on larger sections of road.
