Abstract (en)
[origin: EP1164223A2] Oscillatory amplitude of the lower section (2) relative to the upper section (1), is measured at the excitation frequency. The amplitude is determined at up to 60% of the excitation frequency. The quotient of the values is taken as a measurement of the current degree of ground compaction. An Independent claim is included for corresponding equipment.
