- the hot bitumen is made from a bitumen tank via supply lines and a bitumen injection nozzle with from a water tank water supplied via a water injection nozzle mixed in an expansion chamber of the mixing device.
- the work roll has the advantage that the foamed bitumen directly into the granulated building material mixture can be mixed in before the foam collapses.
- the foamed bitumen is only added shortly before it leaves from the foam outlet nozzles in an expansion chamber one separately for each foam outlet nozzle Mixing device generated.
- the generation of the Foam bitumen only shortly before it leaves the Foam outlet nozzles make this possible in an advantageous manner to dose the foamed bitumen exactly.
- the injector for hot bitumen a tappet adapted to the nozzle cross-section for the nozzle opening, which for periodic Clean or close the nozzle opening using a Control can be driven.
- the plunger is used for cleaning the nozzle Pushed through the nozzle 1 to 2 times per minute, so that the nozzle cross-section is always kept clear. If the nozzle is to be closed, the plunger remains in the Nozzle cross section.

Orthogonal to this free jet are radial or tangential to the circular expansion chamber 26 water through a water injector 22 and Air is injected via an air blowing device 24.
- In the expansion chamber becomes a strong swirl of the expanding foam volume reached, whereby a high expansion number of the foam bitumen as well as a longer half-life can be achieved.
- the air will for example, injected under a pressure of 4 to 5 bar.
- the foam outlet nozzle 14 is eccentric to the expansion chamber 26 and arranged to the bitumen injection nozzle 18, whereby the swirl in the expansion chamber 26 still is reinforced.
- the bitumen injection nozzle is pulsed with the help a plunger 30 periodically cleaned, the plunger controlled by a pneumatic drive device 32 microprocessor is driven.
- the plunger 30 can also be used to close the bitumen injection nozzle 18, if, for example, the foamed bitumen in a reduced width should be sprayed. This is for example for multi-lane, overlapping work meaningful.
