1. A road paver comprising:
a paving screed including a tamper;
a GNSS receiver;
a material conveyor; and
an electronic control system comprising a memory and a data processor, wherein in the memory digital construction data are stored including a target layer thickness of paving material and a pre-compaction degree that depends on the target layer thickness for a respective local coordinate point, and the control system is configured to automatically control compaction performance of the paving screed as a function of the target layer thickness in order to pave the paving material with the pre-compaction degree for the respective local coordinate point of the road paver determined with the GNSS receiver.
