A NEW road surface made from recycled tyres has proved successful during a trial on a busy Scottish dual-carriageway.

The first major UK trial of the new asphalt was carried out last month on a short stretch of the A90 between Perth and Dundee, which carries around 35,000 vehicles a day.

Over the next few months the material will be closely monitored against a number of key performance criteria, including grip and skid resistance after the initial tests proved its viability, the company behind the project, Breedon Aggregates Scotland, said.

The new technology enables the new surface to incorporate rubber particles directly into the asphalt.

A spokesman for Transport Scotland said: "We are pleased that industry has identified this opportunity.

"This adopts a sustainable approach in making the best use of resources available."
