National Highways has reportedly launched a further graphene-enhanced asphalt trial, this time on a one-kilometer section of the A12 between Hatfield Peverel and Witham, east of England. The first trial came in August 2021, when graphene was added to bitumen on the A1 in the North East.
The latest project saw a new surface laid on the A12 northbound, containing 40% reclaimed asphalt – thought to be the highest level ever used in the UK for asphalt with graphene-enhanced polymeric modifier. The performance will be monitored over several years by AtkinsRéalis, which will look at its carbon footprint and whole-life benefits, measuring it against a control section of standard polymer-modified bitumen asphalt.
