Construction firm Skanska has trialled a new form of recyclable asphalt in the UK for more durable roads and to reduce environmental impacts.
The firm is hoping to reduce potholes and increase the use of recycled materials in roads, which is typically 10% on motorways and A-roads.
The new material is made of “high performance” asphalt and “a supermodifier containing graphene and a specially selected plastic”.
Skanska worked with Aggregate Industries and Italian manufacturer Iterchimica to develop the asphalt, which was tested on a 750m section of road in Curbridge, Oxfordshire.
Jim Daughton, operations director at Skanska, said: “Exploring these new materials is about taking a new approach to tackling two of the biggest issues facing the highways industry and UK drivers – reducing potholes and improving the quality of our infrastructure for the future while driving down carbon.
“We’re always looking for new ways to provide best value and our innovative approach enables us to deliver better and more effective projects for our customers and their communities, so we’re delighted to be the first to trial graphene asphalt in the UK and increase the use of recycled materials.”
Paddy Murphy, managing director of contracting at Aggregate Industries, said: “We hope this trial will go on to prove that this asphalt is more durable and can be used across the UK to improve the lifespan of our roads.”
Skanska has also resurfaced a section of the M25 in Essex using an asphalt mixture with 50% recycled materials.
In August, Highways England trialled an asphalt formula using recycled rubber tyres on a stretch of the M1. In May, a road in Scotland was made from 20 tonnes of waste plastics.
