METHOD FOR OPERATING A MOVABLE COMPACTION DEVICE DURING MATERIAL COMPACTION WORK
In the method for operating a movable compaction device (10) during material compaction work the moisture content of the material to be compacted is monitored. The method comprises the steps of defining a compaction performance index for the material (100) to be compacted, said compaction performance index being an electromagnetic character correlating with the volumetric moisture content of the material, determining the compaction performance index value in a number of survey points of the material to be compacted during compaction work using electromagnetic measurement device and controlling the operation on the compaction device based on determined compaction performance index values. Determination of the compaction performance index includes sending at east one wideband electromagnetic pulse to the material to be compacted with a ground penetrating radar, receiving a reflected signal, measuring the power spectral density and peak to peak amplitude from the reflected signal and calculating the compaction performance index by using the measured density and amplitude.
