By compacting at the natural frequency of the asphalt mat, Seismic Asphalt avoids double-jumping of the drum and losing any compaction effort.

At World of Asphalt, Dynapac is introduced its Seismic technology for asphalt compaction.

The intelligent Seismic Asphalt system improves compaction performance significantly compared to conventional compaction carried out at a fixed frequency, according to the manufacturer.

Seismic Asphalt automatically detects the optimum compaction frequency and continuously adjusts it accordingly. Due to the Seismic Asphalt system, Dynapac can offer an increase in efficiency and lower cost of ownership from fuel savings and less wear-and-tear on the roller.

Seismic Asphalt Does it Differently

Traditional double drum vibratory rollers deliver a rapid succession of impacts to the surface at a frequency that is either pre-set at a high or low amplitude or at a frequency that is adjusted manually. Seismic Asphalt from Dynapac does it differently.

Since the drums and the material act as one dynamic system, several benefits can be found from the system's natural resonance frequency. By compacting at the natural frequency of the asphalt mat, Seismic Asphalt avoids double-jumping of the drum and losing any compaction effort.

Seismic Asphalt automatically determines the optimal drum vibration frequency for the compacted material, constantly monitors the variations of the asphalt layer, and automatically adjusts to changing temperature conditions. The operator no longer has to manually set the frequency or guess what asphalt material type or frequency should be used at any given time.

By using the pre-set on the speed limiter, a constant speed and optimal compaction is ensured, thus allowing the operator to focus on meeting the compaction requirements.

Dynapac's well-renowned tools such as Dynapac Compaction Meter and Dyn@lyzer ensure that these requirements are met.

It will be a standard feature for the CC2200VI-CC6200VI and the CO2200VI-CO6200VI roller ranges.
