Derbyshire Expands Pothole Repair Trials with New Technology and Materials

Derbyshire County Council is testing a range of innovative road repair solutions as part of a wider effort to improve the speed, durability and cost-effectiveness of pothole maintenance across the county.

The latest trials form part of the authority's £70 million highways capital investment programme, which is focused on improving road conditions and identifying more efficient ways to maintain the network.

Among the technologies being assessed is the JCB Pothole Pro, a specialist machine designed to streamline the repair process by cutting, preparing and cleaning damaged sections of road in a matter of minutes. The equipment will be evaluated over the next three months to determine whether it can enhance the council's existing repair operations and provide value for money over the longer term.

The trial builds on previous assessments undertaken by the council and forms part of a broader strategy to explore emerging technologies capable of tackling the growing challenge of pothole repairs.

Alongside new machinery, Derbyshire has also been experimenting with alternative repair materials. Over the past 18 months, selected locations have been repaired using an elasto-mastic compound containing recycled rubber sourced from used lorry tyres.

The material is designed to offer greater flexibility than conventional asphalt, helping repairs withstand traffic loads and temperature changes while reducing the risk of water penetrating the road surface. The council says repairs carried out using the product have so far remained in good condition without requiring additional maintenance.

To support work on rural roads, two jetpatching units are also operating across the county. The technology enables crews to repair multiple potholes quickly while minimising disruption to motorists and can be used effectively even during damp weather conditions.

A further initiative involves the introduction of thermal repair techniques on residential streets and in town centres. The process works by heating and reusing existing road materials to create a seamless repair that bonds directly with the surrounding carriageway, producing a waterproof finish designed to extend the life of the repair.

Up to four specialist crews are expected to be deployed across Derbyshire using the thermal repair method through to April 2027.

Councillor Charlotte Hill, Cabinet Member for Highways, said the council recognises the frustration potholes cause for residents and is committed to exploring a variety of solutions rather than relying on a single repair method.

She said ongoing investment in equipment, materials and innovation is helping ensure the most appropriate repair techniques are used for different road types and conditions.

The council currently repairs around 2,000 potholes every week through its rapid response programme, with the latest trials supported by a dedicated highways innovation group tasked with identifying new approaches to maintaining Derbyshire's road network.

By combining traditional maintenance techniques with emerging technologies, Derbyshire hopes to improve the resilience of its roads while making best use of available funding and resources.
