Method For Providing Information Related To The Compression State Of A Soil When Performing A Compaction Process Using A Soil Compressor

A method for assessing soil compaction state utilizes a soil compactor featuring at least one vibratory roller with a rotating imbalance arrangement. An acceleration detection arrangement measures the roller's vertical acceleration (orthogonal to soil) and horizontal acceleration (parallel to soil). The method comprises: (a) detecting these accelerations during movement; (b) determining a measurement relationship ($Z_M$) between ground contact force ($F_b$) and roller deflection ($s_w$) for at least one vibration cycle; (c) determining a simulation relationship ($Z_S$) between $F_b$ and $s_w$ using a ground model with at least one simulation parameter; (d) comparing $Z_S$ and $Z_M$; and (e) concluding that a simulation parameter's default value represents a corresponding soil parameter if $Z_S$ substantially corresponds to $Z_M$.
