High energy impact compaction involves the transfer of compaction energy into the soil by means of the lifting and falling motion of non-circular rotating masses. The rotation of such masses to their highest point results in an effective potential energy build-up. Further rotation of these masses results in the conversion of this potential energy into a falling kinetic energy, which is transferred to the soil upon the impact of the lowest point of the masses with the surface of the soil. The amount of energy transferred, in the form of compactive effort, is closely related to the amount of potential energy generated in the lifting process.
Some typical applications include, but are not limited to:
Deep in-situ compaction
Thick lift compaction
Proof rolling
Compaction of rockfill
Compaction of dredged marine sands
Rehabilitation of quarries and mines
Brownfields rehabilitation
Coal discard compaction
Treatment of unsurfaced roads
Treatment of materials with a high collapsible potential
