After several months of lab-based development, National highways are now live testing the use of in-situ recycling of road surface with added graphene.
These ‘world’s first’ trials are being carried out alongside the Graphene Engineering Innovation Centre (GEIC) at The University of Manchester and Pavement Testing Services (PTS).
DSD Construction is proud to have been involved in the trial of this revolutionary resurfacing technology working alongside SPL, on the northbound carriage of the A1 in Northumberland by providing specialist plant, equipment, and staff to complete the physical works on site.
The trial involved the removal & in-situ recycling of the existing road surface which was also mixed with raw graphene and other materials on-site, to form a new stronger recycled road surface. By recycling the old asphalt into the new road surface material, National Highways will significantly save energy, carbon footprint and cost in the maintenance of highways on the future.
“Graphene’s benefits are industry-changing. It’s stronger than steel and adding it to other materials can turn them into super materials. From what we’ve seen so far, it could make some of our assets last significantly longer. “
Graeme Watt – Asset Needs Manager, National Highways.
The success of this new material will extend the lifespan of busy roads and reduce the frequency of roadworks. This is one of the first steps to achieving carbon reduction within highways construction- moving the industry towards reduced carbon maintenance with longer lasting solutions.
“We are delighted to be involved in this prestigious trial for National Highways which aligns with our plans to maximise efficiency and minimise carbon footprint on all of our future projects by working with technology partners and academia”.
