Abstract
A ground compaction roller, in particular a tandem roller or a single-drum roller, having a machine frame, a drive unit, at least one roller drum mounted on the machine frame for rotation about a rotation axis, an exciter device arranged at least partially in the roller drum, and a sensor device for measuring the compaction of a ground achieved by a passage of the ground compaction roller, said sensor device being arranged on the roller drum in the region of the rotation axis and rotating together with the roller drum during operation of the ground compaction roller. The invention also relates to a method for ascertaining the ground stiffness during ground compaction with a ground compaction roller, in particular a tandem roller or a single-drum roller, comprising the steps of: measuring the acceleration directly at a roller drum which rotates during operation, ascertaining the ground stiffness from the measured values, wirelessly transmitting the measured values and/or the ground stiffness values to a receiving device.
