Abstract
A fumes abatement system for an asphalt paving machine is disclosed for dispelling noxious fumes that are emitted from asphalt in the hopper of and from behind the paving machine during paving operations. The fumes abatement system utilizes existing plate walls of the feeder tunnel and superstructure to eliminate additional parts and for increased durability. A high capacity blower and a tall exhaust stack are used to disperse the fumes well above the operators of the machine.
