Seismic Asphalt

Compaction Redefined

With a Seismic Asphalt machine you benefit from increased productivity, energy- and cost efficiency as well as operator comfort and simplicity. The Patented Seismic innovation by Dynapac is unique and is the only system on the market that is completely automatic with no need for additional operator training.
 


Excellent Operator Comfort

The machine operates at a lower noise level and transmits fewer vibrations to the cab, thanks to reduced frequency levels. This results in a more pleasant experience for the operator, allowing you to enjoy your workday in a quieter, smoother, and more comfortable cab.

 

Select and go

Starting a machine with Seismic is incredibly simple, as Seismic is automatically activated by default. Just pick high or low amplitude. That’s it. You’re ready to roll.

Thanks to lower frequency vibrations, the improvement is evident both inside the cab and in the area around the machine. You get a calmer, more comfortable workspace that enhances both focus and overall operator wellbeing.

How the System Works

The system provides real-time monitoring and continuously adjusts the frequency automatically based on the material. No additional training is required and no risk of getting the compaction settings wrong. By working in harmony with the material being compacted, it significantly reduces issues like bouncing and aggregate crushing. This fully automatic compaction process eliminates operator guesswork, ensuring optimal performance for any material or layer thickness.
 

 


Reduces Wear and Tear

Thanks to Seismic and the optimized frequency adjustments, the vibration powertrain and drum shells are exposed to less stress and wear compared to conventional compaction. This, in turn, means a longer life of the vibration mechanism and related hydraulics. On top of this, Dynapac´s already durable and thick drum shells will last even longer, maximizing the drums lifetime.


Seismic Delivers More

EcoMode

With the EcoMode setting enabled, the machine operates at the lowest possible RPM without compromising compaction quality. The machine automatically idles after 10 seconds in neutral, significantly reducing engine RPM. This feature does not interfere with the general workflow or operation of the machine and ensures instant start-up after idle mode. 


Temperature Meter

Dual asphalt temperature sensors mounted within outermost crossbeams of both drums allowing the operator to continuously monitor surface temperature. Keeping track of the asphalt’s temperature is critical to asphalt compaction, consequently Seismic Asphalt utilizes the temperature readings to adjust both drum’s frequency – the only system in the industry, which constantly uses the temperature to adjust.


Compaction Meter

The Dynapac Compaction Meter provides real time stiffness measurements to ensure optimal compaction. The compaction meter can present two different values for the operator, EVIB1 and EVIB2. The optional system is standard with Seismic Asphalt. The same sensors for the compaction meter are used to calculate the frequency adjustment of the Seismic Asphalt system.
