Dragon PatcherNew technology provides a fast, efficient and sustainable solution to pothole repair
Potholes are an increasing problem on our roads. Traditional ways of preventing and repairing potholes are both costly and time-consuming, with lengthy operations disrupting traffic flow and inconveniencing city motorists.
Peterborough Highway Services, a partnership with Peterborough City Council and Skanska, is using new technology from Sweden to provide a safe, fast and environmentally sustainable solution. The ‘Dragon Patcher’ – nicknamed due to its fire emitting nozzle — is operated by one person in a cab. The area which needs repairing is cleaned with compressed air and then sealed with a combination of stone chippings and hot bitumen emulsion. The surface is then ready to take traffic. In colder weather conditions a flame is applied to warm the surface. The patcher also treats minor cracks and crazing that could otherwise develop into potholes, thereby treating a potential defect before it occurs.
The patcher is proven to be significantly quicker at repairs, and costs are almost half those incurred using the traditional method. There is less waste and, most importantly, it is safer for road workers. The outcome of the UK trials showed that the Swedish patcher was twice as quick when compared with a manual repair solution.
In Peterborough, the patcher has increased productivity four times over and reduced costs by 50%.
