Soil compaction of fills performed by surface force is a process of key importance for road construction. Road rollers represent the most widespread type of compactors. Improvement of both quality of compaction and output of roller is technological problem of great interest. The key point for its solution is optimal choice of combination of parameters which determine the force causing plastic deformation of the soil layer. Theoretical consideration of the process is given in the framework of interaction between massive elastoviscoplastic region of soil layer and source of external surface force. It naturally produces resonance criterion for the energy effective compaction. Minimum value of mechanical resonance in respect to external force allows to find the combination of working regime parameters for the given type of roller. Results of experiments involving sandy loam and clay loam proved the results of numerical modeling and gave key for recommendations on combined speed-frequency energy effective regime of compaction for given types of soils by smooth drum vibratory roller.
