In a road finishing machine comprising at least one screed, a machine control, and a ventilation system including a fan, the fan can be switched on or off via the machine control automatically independent of the operator and exclusively depending on demand. According to the invention, before or during the laying operation, a defined demand for the operation of the ventilation system is determined, and during or for the laying operation, the ventilation system is operated independent of the operator and automatically, and optionally power-controlled, upon determination of the defined demand.

1. Road finishing machine comprising at least one screed, a machine control, and a ventilation system for drawing in and discharging collected irritants released by a material mixture processed by the road finishing machine, the ventilation system including at least one fan that can be switched on and off,automatically exclusively depending on a demand for the operation of the fan of the ventilation system determined by a machine control or a ventilation system control,wherein the machine control or the ventilation system control comprises a ventilation system operation demand decision section that acquires and processes information one or more of a material mixture type, an operating mode of the screed or the road finishing machine, from a road finishing machine function pre-selection or setting device or from a temperature measuring device of the road finishing machine, to automatically decide whether or not to demand operation of the fan of the ventilation system. 2. Road finishing machine according to claim 1, wherein the road finishing machine comprises at least one device for measuring an actual value of the temperature of the material mixture, and/or a material mixture laying temperature a screed heating temperature or an irritant concentration, the device being situated in the region of a material hopper a longitudinal conveyor, the screed or an irritant withdrawing region of the road finishing machine. 3. Road finishing machine according to claim 1, wherein the machine control comprises an operator-controlled input section for entering information on one or more of material mixture types, material mixture temperatures, material mixture laying temperatures, compaction settings of compacting tools of the screed, screed heating temperatures, operating modes or machine functions of the road finishing machine. 4. Road finishing machine according to claim 1, wherein at least the machine control is linked online to a construction site management system for acquiring information on material mixture types and/or or the ventilation system operation demand decision section. 5. Road finishing machine according to claim 1, wherein an irritant concentration measuring device is provided in an irritant collecting region of the road finishing machine, and is linked to one of a device for switching the ventilation system fan fan on or switching-off or a ventilation system fan power control device. 6. Method for laying an asphalt material mixture on a foundation by a road finishing machine having a screed and further comprising a machine control and a ventilation system for collecting and discharging irritants released from the material mixture processed by the road finishing machine, the ventilation system including at least one fan that can be switched-on and off, the method comprising determining a demand for operation of the ventilation system before or during the laying operation based on an operating mode or machine function of the road finishing machine, a material mixture type, a material mixture temperature, or an irritant concentration, and switching-on the fan automatically and operating the ventilation system at least for the duration of the determined demand. 7. Method according to claim 6, comprising determining and implementing the demand for operation of the ventilation system independent of an operator with the machine control or a ventilation system control. 8. Method according to claim 6, comprising automatically switching-off the fan during a site-changing operation or a transport travel of the road finishing machine. 9. Method according to claim 6, comprising automatically controlling the speed of the fan of the ventilation system on the basis of a comparison executed between a set target value and a measured actual value of an irritant concentration.
