Zusammenfassung:	The machine has a frame with working roller below a roller housing (8). This has a spray device (10) for water or binding agent, with a nozzle (12) direction into a working chamber. The nozzle has a controlled closure device (18) with closure element (22), to open and close the nozzle. The closure device can initiate a further movement of the closure element past the closing position, to remove collected material in and/or in front of the nozzle. The nozzle is connected to ring pipe (14) or a tank. The spray device has a mixer unit (36) with expansion chamber (38), and a bitumen injection nozzle (40) to mix hot bitumen with water or with water and air, for ejection of foamed bitumen from the spray nozzle.
