Abstract:
According to a method for constructing a cover layer S on a planum M by using a paving screed B the elevation of the paving screed B above the planum M is measured using a reference RZ on the planum M by at least one elevation sensors H and/or the lateral inclination of the paving screed B with respect to the planum M is measured by at least one lateral inclination sensor N. Upon occurrence of a deviation from the target elevation pulling points P of pulling bars 6 of the paving screed B are displaced vertically at a road paver F by levelling cylinders Z. Each levelling cylinder Z is exclusively adjusted over an absolute stroke starting from a selected zero point NP. The absolute stroke is calculated from a measuring result of a reference measurement and by consideration of a construction ratio factor. A new adjustment position of the levelling cylinder Z resulting from the adjustment over the absolute stroke in a self-learning fashion automatically is selected as the new zero point NP for a subsequent regulation cycle.
