The roads and pavements in Sheffield are getting repaired using a new rubber-modified road surfacing material made from old tyres. Amey has collaborated with local manufacturer Roadmender Asphalt for this innovative reconstruction project.
The studies have shown the mastic asphalt-based material is hard-wearing and could speed up road repairs significantly. The materials can be used to repair a wide variety of surface defects in roads and pavements including potholes, surrounds of manholes and gullies, and cracks.
Heating up of the sticky rubber content makes it flowing. It effectively spreads beyond the edges sticking to the surface by making it watertight by flowing into cracks and cavities after pouring into a pothole or crack.
