Superior Paving field tested a Dynapac CC2200 VI asphalt compactor with Seismic technology on a stretch of Interstate in Virginia. The test came as part of Dynapac’s rollout of the technology on its large asphalt rollers.
Seismic automatically detects the frequency of the material and adjusts the vibration, according to Dynapac, which leads to 30% fuel savings, a more comfortable ride for the operator, and less wear and tear on the machines.

“The operation of this system is straightforward and user-friendly,” said Andreas Persson, a Dynapac engineer, in a statement. “The operator simply selects the high or low amplitude setting, and the machine manages the rest. This simplicity allows the operator to concentrate on navigating the track and ensuring safety, without the need for complex inputs or adjustments.
“It’s all about ease of use: Just set the amplitude, and you’re ready to go.”
The Dynapac CC2200 VI roller weighs 7.6 tons and features a 59-inch drum, which is ideal for finish rolling, according to the company. It includes a Tier 4 Final diesel engine with a high torque setting, efficient patented eccentric weights, and an Eco mode for fuel efficiency. Seismic technology is designed to further optimize compaction efficiency, reduce fuel consumption, and enhance operator comfort.
Michael Washington, a roller operator at Superior Paving, highlighted the roller’s impact on the highway project.

“We’re doing the base asphalt layer on Interstate 95, which runs from Florida to Maine,” said Washington in a statement. “The highway has been undergoing significant widening in Virginia to accommodate increasing traffic, especially toward Washington, D.C. The CC2200 VI roller with Seismic technology has been crucial for the final compaction of the base, intermediate, and topping layers. Its variable-compaction mechanism ensures the right amount of compaction with minimal passes.”
Said Evan Pugh, a density tech QA at Superior, said the technology allows the company to achieve consistent density, even close to the edges of the mat.
“We’ve conducted extensive tests to ensure its performance in various conditions,” said Persson. “This adaptability is crucial for different contractors working on diverse job sites around the globe. So far, the machine has performed well and achieved the desired compaction levels across the board.”
