Abstract

The invention relates to a road paver (1) comprising a paving screed (11) wherein the paving screed (11) comprises a tamping machine (21) and the road paver (1) further comprises a GNSS receiver (13) and a material conveyor (7). The road paver (1) further comprises an electronic control system (15) comprising a memory (17) and a data processor (19), in which digital construction data (37), in particular a target height profile (43) of the road surface (28) to be paved, a target layer thickness (dS) of the paving material (5) and, if necessary, a height profile (39) of the roadbed (27) are stored in the memory (17). The control system (15) is configured to automatically control the compaction performance of the paving screed (11) according to the target layer thickness (dS) to pave the paving material (5) for each local coordinate point (41) of the road paver (1) determined by the GNSS receiver (13).

Description

technical field [0001] The invention relates to a road paver and a method for operating a road paver. Background technique [0002] In road construction, it is often found that the subgrade (ie the base prepared for the application of the road surface) still has unevenness. Therefore, it is necessary to level these unevennesses when paving the road in order to obtain a level road surface. For this purpose, it has hitherto been known to control the leveling cylinders of road paver machines in order to vary the layer thickness of the road surface by means of conventional leveling methods so that thicker layers of paving material are used to level depressions and thinner layers Use the best paving material to level the bumps so that a perfectly level pavement can be paved across the board. However, the above method has proven to be disadvantageous, because the subsequent compaction by the rollers can again cause unevenness in the paved road, because thicker layers have a larg...
