asphalt bitumen foaming and mixing device

  • Cold recycling - Foamed bitumen - WIRTGEN GmbH

    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. It is eminently suitable for mixing with cold and moist construction materials.

  • LOW TEMPERATURE Ammann

    Low-temperature asphalt production is perfectly compatible with the use of reclaimed asphalt, because the lower mixing temperatures cause less oxidation of the bitumen contained in the RA. Since there is also less aging of the fresh bitumen during the mixing process, improved low-temperature behaviour can be expected from the blacktop.
