Holes And Cracks In Asphalt May Be Numbered. A UK-Developed Innovation Uses Graphene — A Material 200 Times Stronger Than Steel — To Create More Durable And Flexible Pavements Capable Of Withstanding Temperature Variations And Heavy Traffic Without Degrading Quickly
Holes in the streets are a universal problem that affects drivers all over the world. However, a new British technology may represent the end of this hassle. The secret lies in a material reinforced with graphene, one of the strongest substances known to science.
Technology Tested On British Roads
In the UK, the new type of asphalt has shown very promising results compared to the traditional model.
According to a report by the BBC, a local council stated that it was “very encouraged” by the material’s performance after the initial tests were conducted.

Scientists have discovered a hidden underwater “portal” beneath the largest glacier in East Antarctica, capable of carrying warm water to the ice base; Totten drains a colossal basin with the potential to raise sea levels by more than 3.5 meters.

For the first time in history, scientists are observing the Pacific crust tearing on the ocean floor and revealing the birth of an underwater tectonic division.
Just like in Brazil, British roads consist of a mix of stones and bitumen. The difference now lies in the graphene reinforcement, which makes the pavement more resistant to temperature variations and heavy traffic.
More Expensive Asphalt, But Much More Durable
In 2022, Essex Highways applied the graphene asphalt on the A1016 in Chelmsford. The material was developed by the British company Eurovia, which was looking for ways to enhance traditional pavement.
“When we found a graphene additive — a thin, strong, and flexible form of carbon — that we could mix with hot rolled asphalt, Essex Highways agreed to be the first to test it,” said the company’s director, Paul Goosey, in an interview with the BBC.
Despite the higher cost, the gain in durability is considerable. The BBC reports that the enhanced material costs £2.50 (about R$18.26) more per square meter than standard asphalt, but the expectation is that it will last much longer.
What Makes Graphene So Strong
According to Mundo Educação, graphene is obtained by extracting surface layers from graphite, a material abundant in nature.
It is considered the strongest material ever discovered, withstanding pressures of up to 130 gigapascals (130 × 10⁹ Pa).
This combination of lightness, flexibility, and strength makes graphene a potential ally for the future of roads worldwide.
