Cold recycling - Foamed bitumen - WIRTGEN
Foamed bitumen is produced by foaming standard road-grade bitumen. In the process, small amounts of water and air are injected into the hot bitumen at high pressure, which results in the bitumen foaming and expanding to around 20 times its original volume. The bitumen foam is then injected into a mixer via injection nozzles.
