PROBLEM TO BE SOLVED: To adequately evaluate the situation of earth compaction only by a simple data analysis. SOLUTION: An earth compaction control equipment 1 comprises an accelerometer 2 for measuring acceleration is the vertical direction of a vibrating body installed in a rolling machine during rolling operation, a filter 3 for outputting corrected acceleration data by removing fundamental vibration frequency components from acceleration data measured with an accelerometer, an integrating circuit 4 for determining a time average by integrating the measured acceleration data and corrected acceleration data by respective absolute values, and an arithmetic circuit 5 for obtaining an integration ratio by dividing the integrated value of the corrected acceleration data determined by the integrating circuit by the integrated value of the measured acceleration data.
