Dynapac SEISMIC: Maximum Compaction with Minimal Effort

9a368b13

SEISMIC Asphalt works to match the vibration frequency of the drum to the natural resonance frequency of the asphalt and drum system.

Hot asphalt is easier to compact, but as it cools, more compactive effort is necessary. Conventionally, more amplitude is necessary to continue to get more density.

Amplitude is amplified when the vibration frequency is in tune with the natural resonance frequency. Adjusting closer to the “sweet spot” of the natural resonance gives an “amplitude boost” for more optimal compaction

This allows for maximum results with minimal effort and a reduction in wasted energy.
