Aggregate Industries has commenced work on a major road improvement project from Cambridge to Huntington.

The first section of Highway England's A14 scheme will see 13 miles of the road upgraded to three lanes in each direction and journey times cut by up to 20 minutes.

Aggregate Industries suggested the use of its 10mm SuperThin asphalt to meet stringent noise restrictions at Brampton Hut motorway services.

SuperThin, at 7.8db(A), by far exceeds the minimum sound level requirements, rather than the -3.5db(A) associated with traditional hot rolled asphalt (HRA).


The company's contracting division has already laid 2,200 tonnes of SuperThin.

Approximately 2,200 tonnes of SuperThin is expected to be installed throughout the contract, which is due to be complete at the end of 2020.

Paddy Murphy, Director of Contracting at Aggregate Industries, said: "As the sole pavement contractor and supplier to the UK's largest and most prestigious road improvement project, one of our key aims is to help reduce the impact of operations on the local community and the network.

"One way we're doing this is by ensuring that our asphalt solutions reduce excessive noise pollution to those residing in the built-up areas of the scheme. As the only HAPAS-approved ultra-low noise asphalt available to the UK market, our SuperThin asphalt far exceeds the minimum noise limits at Brampton Hut Services. This solution, along with our exceptional customer service, is receiving great feedback from the A14 Integrated Delivery Team as it continues to be deployed across the rest of the project."
