Oxfordshire council, working with a private contracting company, have proposed trailing the use of graphene-enhanced type of asphalt for roads.

The trail in Curbridge, Oxfordshire, will be led by graphene specialist Directa Plus, who produce and supply graphene-based products for consumers and industrial markets. The trail will see 750m of road laid using asphalt concrete with a proprietary graphene-enhanced super modifier.

Known as G+, the modifier will be laid into the two upper layers of the road surface. With cooperation of Oxfordshire County Council, Skanska will work as the prime contractor for this venture.

The super modifier will be compared with traditional asphalt in order to assess; service life, vehicle resistance, resistance to deformation and permanent plastic deformation. This trail is taking place after similar trails in Italy were highly successful.

Skanska UK operations director Jim Daughton said: “We’re always looking for new ways to provide best value for our customers and their communities, so we’re delighted to be the first to trial graphene asphalt in the UK.

“If successful, this innovative, fully recyclable product will help us more than double the durability of asphalt used in highways maintenance, thus significantly increasing the lifespan of our roads, while reducing carbon, which is key as we work with our supply chain to achieve net-zero carbon emissions by 2045.”

Directa Plus chief executive Giulio Cesareo said: “This trial is an important step for Directa Plus and Iterchemica, in partnership, in proving the business and use case for the next generation of graphene enhanced road surfaces.

“This technology will allow governments to supply better quality roads for drivers and other road users, at better value for money, and in a more environmentally sustainable way.

“Working with leading companies such as Iterchemica to bring the benefits of G+ graphene enhanced products and materials to market is a key part of Directa Plus’ strategy across all our key industrial verticals.”
