Highways England has dubbed a new type of material an “anti-ageing cream for roads” and says it could prevent the need for roadworks and reduce environmental impact.
England’s motorways and major A-roads are expected to be resurfaced every 10-12 years because water, sun and air, combined with the weight of heavy traffic, causes the surface to deteriorate and crack.
The asphalt mix, which is held together by a new bitumen, is designed to be more resistant to the elements, by oxidising more slowly. It means that the road surface stays flexible for longer, preventing cracks forming.
A section of dual carriageway in Northamptonshire has become the first in the country to be resurfaced with the new material.
“The ultimate priority for us is safety so we invest in new technology and materials to keep those using the roads safe,” said Mike Wilson, Highways England’s Chief Highways Engineer.
“Longer lasting roads means fewer roadworks, less disruption for motorists and a more sustainable network for everyone.”
