Abstract
An apparatus for compaction of soil and asphalt includes a first mass, such as a compaction drum, or vibrating plate, a second mass configured to oscillate vertically and an unbalanced shaft configured to vibrate the first and second masses. Wherein removable masses can be added and removed from the second mass, in order to enable resonance vibration of the first and second masses, thereby doubling and even tripling the compaction forces applied to the surface being compacted.
