British motorists pay a high price for repairs to damage caused by potholes. Claims for pothole damage are estimated to total around £4 billion annually, according to insurer Green Flag. And such is the public outcry over the state of the country’s roads that the government set aside a fund of £2.5 billion in the latest Budget to address the problem. To addres this, Roadmender Asphalt, a Sheffield-based bitumen technology company, has developed a novel approach to pothole repairs. The company uses mastic asphalt, one of which is called Elastomac. This novel thermoplastic includes seven end of life tyres in every tonne.
