A roller flap position correction mode can be activated manually or automatically. In the roller flap position correction mode, the position of the rear roller flap is optimised so that an accumulation of material is largely avoided. The control device of the roller flap adjustment device is designed in such a way that in the roller flap correction mode, the floating position of the rear roller flap is cancelled in a first step and the rear roller flap is pivoted upwards from a first pivoted position into a second pivoted position. In a second step, the floating position is set again, so that the rear roller flap assumes a third pivoted position in which the lower edge of the rear roller flap rests on the ground. After the floating position has been reset, a checking routine is carried out, which includes at least one checking cycle.

A machine train is composed of a road milling machine that travels in front and a road finisher that travels behind. The road milling machine has a profile data determining device configured so that a sequence of height profile data describing the height of the road surface in the longitudinal direction is determined while the road milling machine advances. For transmission of the height profile data, a data transmission device is provided on the road milling machine and a data receiving device is provided on the road finisher. To change the position of the screed, the road finisher has a levelling device that comprises at least one actuator and a control unit, which is configured so that the control unit generates a control signal for controlling the at least one actuator in accordance with a height profile data set.

A system and method are provided for the tracking of material milled via a milling machine, to improve recycling possibilities for the milling material. The milling material removed during milling is deposited onto a vehicle for transport to a deposition site. A first detection device associated with the milling machine detects data signals relating to the milling material, and the milling material is tracked via a documentation device comprising a user interface, based at least on the data signals. The documentation device may selectively display which milling material has been unloaded at a particular deposition site. A marking device may be provided to mark the milling material or the transport vehicle, and/or a second detection device may be provided to detect position data corresponding to the deposition site, wherein the marking and/or position data are interlinked with the data signals relating to the milling material in the documentation device.
