Abstract

A method for providing information related to the compaction state of soil when performing a compaction operation with a soil compactor includes: a) detecting a vertical acceleration and a horizontal acceleration of a vibratory roller when moving a soil compactor over soil to be compacted, b) determining a measurement relationship between a ground contact force and a deflection of the vibratory roller for one vibration cycle using the vertical acceleration and horizontal acceleration detected in operation a), c) determining a simulation relationship between the ground contact force and the deflection for one vibration cycle using a ground model taking into account at least one simulation parameter, d) comparing the simulation relationship to the measurement relationship, and e) determining that a default value of the at least one simulation parameter taken into account in the ground model substantially represents a corresponding soil parameter of the soil to be compacted when the simulation relationship substantially corresponds to the measurement relationship.
