First carbon neutral roadworks completed in UK

The UK’s first carbon neutral pavement scheme used cold recycled asphalt mixed SuperLow asphalt, produced off site, to make a carbon neutral paving surface

The Contracting Services division of Aggregates Industries (AI) has completed work on the UK’s first carbon neutral pavement scheme.

AI worked with principal contractor AE Yates and design company AMEY to deliver the A590 M6 J36 scheme for Highways England - the government company responsible for the operation, maintenance and improvement of the country’s motorways and major A roads.

The project saw AI carry out resurfacing works to the A590 road and the roundabout at junction 36 on the M6 motorway to Brettarg Holt, which is located north of the city of Manchester.

AI removed the top 32cm (12.5in) of the existing pavement surface and used it to produce an ex situ cold recycled asphalt. This was then mixed with the company’s SuperLow asphalt to make a carbon neutral paving surface.
