ROAD bosses in Southampton are preparing to unleash a "miracle" pour and fix pothole putty to fill frost damaged roads after this weekend's cold snap.

Construction firm Balfour Beatty, which signed a 10-year £100m deal to improve the city's crumbling roads, will begin using the putty to blitz potholes across city.

The product, called Viafix, can be simply poured into a pothole, even if it is full of water, to create a instantly drivable permanently fix that lasts longer than traditional black top fillings.

The recent sub zero temperatures, snow, compacted ice, salt and grit on the roads has created hundreds more potholes in the city with more cold weather to come.

The council's roads boss, councillor Matt Dean said: "We all know the Southampton's roads need a lot of work and investment to get them up to a good standard. Balfour Beatty WorkPlace is really tackling this head on and bringing in new technology and techniques to fix our roads faster and more effectively."

Meanwhile a multi-million pound programme to return Hampshire's roads to the condition they were in before the impact of last winter's weather has just been completed.

A total of 63 miles of roads have been resurfaced or repaired as part of Operation Restore with 53,000 tonnes of surfacing material laid in over 200 locations across Hampshire.

A second operation, Resiliance, will start next year to repair and strengthen more roads to withstand severe weather including snow, ice and flooding.
