Breedon and Nynas have announced the first trial of a low carbon asphalt in Scotland using a bitumen containing a biogenic component.
The material was laid on the A92 in the north east of the Scottish trunk road network in January and has to comply with the Transport Scotland TS2010 specification.
The new low-carbon asphalt, part of the new Breedon Balance range of materials, was successfully installed in collaboration with Transport Scotland and Amey, the network contractor for the region.
It is thought to be the first time an asphalt containing biogenic materials has been used on the Scottish network, Breedon said.
The Nypol RE range from Nynas, incorporating a biogenic component, substantially reduces the carbon footprint of the polymer modified bitumen compared to a normal polymer binder.
The trial aligns with Transport Scotland's aim of reducing carbon emissions by 75% by 2030.
Ken McNeil, head of technical at Breedon, said: 'We carried out a full laboratory evaluation of our TS2010 material using Nypol RE 103 from Nynas and presented these to Transport Scotland prior to seeking approval to use on the Scottish network.
'We are grateful to both Amey and Transport Scotland for giving us the opportunity to proceed with a live trial.'
The move follows successful trials in England, Breedon added.
Cold Comfort Scotland extreme weather maintenance conference takes place at the Macdonald Inchyra Hotel, Falkirk on 20 April 2023.
