Abstract
The disclosure relates to a road construction machine configured in the form of a road paver or in the form of a feeder vehicle for supplying a road paver with paving material, wherein the road construction machine has at least one ventilation system with a suction side for generating negative pressure for extracting bituminous vapors and with a discharge side for generating positive pressure for blowing out the extracted bituminous vapors. The road construction machine further includes at least one spraying device provided on the discharge side for spraying an exhaust air flow formed there from extracted bituminous vapors with an atomized liquid.

A road construction machine configured as a road paver or a feeder vehicle for supplying a road paver with paving material, wherein the road construction machine comprises a ventilation system with a suction side for generating negative pressure for extracting bituminous vapors and with a discharge side for generating positive pressure for blowing out the extracted bituminous vapors, and a spraying device, wherein the spraying device is provided on the discharge side for spraying an exhaust air flow formed there from extracted bituminous vapors with an atomized liquid.
A method comprising:
- generating negative pressure on a suction side of a ventilation system on a road paver and/or on a feeder vehicle for a road paver to extract bituminous vapors on the suction side;
- generating positive pressure on a discharge side of the ventilation system to blow out the extracted bituminous vapor;
- and
- spraying an exhaust air flow formed from the extracted bituminous vapors with an atomized liquid.
