1. An automotive road construction machine, comprising;
- a working drum mounted at a machine frame for working a ground surface or traffic surface;
a combustion engine for driving the working drum;
a drive train between the combustion engine and the working drum, the drive train including a clutch having an input side and an output side;
at least one vibration damper and/or vibration absorber coupled to the output side of the clutch, the at least one vibration damper and/or vibration absorber including;
a connecting device connected to the output side of the clutch;
a flywheel mass; and
an elastic element connecting the flywheel mass to the connecting device; and
wherein the said vibration damper and/or vibration absorber eliminates or reduces rotary vibrations generated by the combustion engine.

9. An automotive road construction machine, comprising:
-
a machine frame; a working drum supported from the machine frame for working a ground surface or traffic surface; a combustion engine for driving the working drum; a drive train between the combustion engine and the working drum, the drive train including a clutch having an input side and an output side; and at least one vibration damper and/or vibration absorber coupled to the output side of the clutch, the at least one vibration damper and/or vibration absorber including an additional mass arranged coaxially to an axis of rotary vibration in which the rotary vibrations of the combustion engine are occurring, and radially towards the outside, with the said additional mass capable of being excited to rotary vibrations which counteract the rotary vibrations of the combustion engine, wherein the said vibration damper and/or vibration absorber eliminates or reduces rotary vibrations generated by the combustion engine.
