Tests have shown that a new road surface technology could be more resistant to general wear and tear.
A trial to see if the use of graphene, the strongest material ever measured, can increase the lifespan of Essex roads is showing positive results.
The trial has involved a graphene-enhanced surfacing material, Gipave, added to hot rolled asphalt and used on roads in Essex since 2022. This is the first time it has been used in this way in the UK.
Graphene material is 200 times stronger than steel yet extremely flexible. It makes the asphalt far less susceptible both to hardening and cracking in cold temperatures, or softening in warm temperatures.
Early results of the trial suggest it is far more durable than traditional materials. It could reduce the risk of potholes forming by up to 20 percent.
Councillor Tom Cunningham, Cabinet Member for Highways, Infrastructure, and Sustainable Transport, said: “We are very encouraged with the results of the trial. These dramatic improvements are what we need in the long term, as it means our roads will potentially need less repairing and maintenance.
“Essex has 5,000 miles of roads and some of the highest levels of traffic in the country, so it is paramount we find new and efficient ways of maintaining them.
“Innovative approaches to road maintenance help us to create a county that is accessible to all, while also giving residents the best value for their money.”
If the current results continue, graphene has the potential to positively impact road repairs in the county.
Essex County Council will decide whether to adopt it as part of road repairs on a permanent basis.
