Using recycled material to refurbish roads usually only applies to the lower layers, using materials such as rubble from demolished buildings. Hamburg’s goal in this example was to recycle 100% of all materials during the resurfacing works on the City’s main street. The bitumen component therefore had to be recycled as well as aggregate materials. The City allowed a group of private companies who originally came up with the idea to test its use on roads not used by the public. After a series of tests, the City was reassured about the quality of the 100% recycling process. A restricted tender procedure was conducted and 5 companies made a bid. The contract was carried out successfully in 36 hours, keeping travel disruption to a minimum. The Municipality saved 30% compared to usual costs for road resurfacing, which equates to approximately €20,000.
