As part of its rolling scheme of civil engineering improvements, Derbyshire County Council had identified a number of high traffic hotspots where the road surface had failed.
These failures included plucking, fretting and pot holing and had occurred much earlier than would be expected in the lifespan of a durable road service.
Most of the areas identified were high traffic roundabouts and junctions used by an increased number of large heavy goods vehicles, which means greater stress had been applied to the road than might otherwise be expected.
To remedy this problem, Derbyshire County Council set about facilitating a competitive tender process to find a product solution that would withstand the high traffic volumes and turning stresses identified at these particular sites.
We were selected as the manufacturer of choice for the supply of a high-quality and durable road surfacing Asphalt, suitable for high stress areas.
The product selected was SuperCurve – a high performance 10mm polymer modified Asphalt designed and engineered to provide an enhanced surface course for areas such as the ones identified in Derbyshire.
Created to meet the needs of the local authority’s road renewal programme, as well as providing a hard-wearing solution for new networks, SuperCurve is a high PBM bitumen with dense in-situ void properties of <5%, capable of withstanding the torsional forces seen on high-stress areas of UK roads.
Launched at the beginning of 2015, SuperCurve has already proven a popular product solution for a number local authorities up and down the country, which is a clear demonstration of our commitment to designing and manufacturing products which exceed the expectations of even the highest specification.
