Abstract
A slip form paving machine includes a machine frame, a plurality of ground engaging wheels or tracks, and front and rear height adjustable lifting columns supporting the machine frame from the ground engaging wheels or tracks, the lifting columns being adjustable to adjust a longitudinal inclination of the machine frame in a paving direction. A slip form mold is supported from the machine frame for molding a mass of concrete into a formed not yet hardened concrete slab as the paving machine moves forward in the paving direction. An oscillating beam is supported from the machine frame behind the slip form mold for engaging and oscillating transversely to the paving direction upon an upper surface of the formed not yet hardened concrete slab to smooth the upper surface. A roll size sensor is configured to detect a size of a roll of not yet hardened concrete created in front of the oscillating beam.
