Dynapac is reentering the 15-tonne asphalt roller category with the launch of the all-new CC7000 VI, the heaviest asphalt roller in the world.
With an operating weight of more than 14,500 kg, the CC7000 VI sets a new benchmark for size, performance and durability.
“It comes from the legacy DNA of the CC722, which has been in high demand from for contractors, and we’ve listened,” said Jennifer Bishop, Dynapac’s Director of Product Marketing and Customer Experience. “So, we’ve come out with this massive machine that also has the widest drum diameter in its class.”
Built for the most demanding large-scale applications, the CC7000 VI is engineered to deliver exceptional compaction results while maximizing productivity. Equipped with Dynapac’s patented Seismic Asphalt technology, the roller automatically adjusts vibration frequency in real time based on material stiffness to ensure optimal compaction, reduced energy consumption and lower operating costs while operator comfort is enhanced from less shaking and less noise.
“Dynapac is excited to reenter the 16-ton classification with a machine that pushes the boundaries of performance and efficiency,” said Eric Booth, Product Marketing Manager for Compaction. “The CC7000 VI reflects our commitment to innovation and to delivering equipment that meets today’s toughest jobsite requirements.”
Legacy inspired
The CC7000 VI is built on Dynapac’s decades of compaction expertise, drawing design inspiration from the CC722 and CC7200, as well as the company’s high‑performance soil rollers. Its newly engineered drums offer one of the highest static linear loads in the market — up to 211 pli — ensuring the roller can withstand the harshest application conditions.
Featuring a compaction width of 213 cm, the asphalt roller is powered by the 154-hp Cummins F3.8 Stage V water cooled turbo diesel engine.
The CC7000 VI is equipped with a 140 cm drum diameter, the largest in the asphalt range. This reduces rolling resistance and shovelling of the asphalt. The CC7000 VI is built for maximum compaction performance with a static linear load of 33.8 to 38.2 kg/cm.
The new drum design takes inspiration from Dynapac’s soil rollers, built for durability and the toughest jobsites. The drum features cartridge designed eccentric housing with a significantly reduced oil amount. Dynapac’s patented Efficiency Eccentrics delivers a 50 per cent reduction in energy needed for vibration start-up and leads to reduced wear and tear.
Operator-focused
The CC7000 VI is designed with the operator in mind. The intuitive operator station features a sliding seat with 180-degree or full rotation. As well, the controls and display move seamlessly with the operator, improving visibility and ergonomic operation throughout the compaction process.
A large-capacity water tank further enhances productivity by minimizing refill downtime and a 4-3-2 full back-up sprinkler system.
Seismic Asphalt
Dynapac’s Seismic Asphalt, a patented technology, is available on tandem, oscillation and pivot-steer asphalt rollers. It is the only system on the market that automatically harmonizes vibration frequency with the natural frequency of the asphalt layer. Seismic Asphalt was a finalist in the technology category of the 2026 Next Level Awards at ConExpo.
“This is the world’s first patented system that adjusts the asphalt temperature and natural frequency. This unit optimizes the vibration five times per second, and it’s simple. It’s simplicity for the operator,” Bishop said. “There’s nothing for the operator to do but adjust the amplitude based on the math.”

Proper asphalt compaction is critical to road longevity. In fact, a 1 per cent increase in density can extend a road’s life by up to 10 per cent. Achieving this precision has traditionally relied on operator expertise, but now, that knowledge is built into the machine as a default setting.
As asphalt cools, compaction effort must increase, but doing so incorrectly risks over-compaction and aggregate damage. Seismic Asphalt solves this challenge by using infrared sensors to measure temperature and combining that data with stiffness and frequency readings. The system calculates and adjusts to the optimal vibration frequency, ensuring compaction is always performed at the best point.
Rather than simply display temperature, Seismic Asphalt uses this information to make smart, automatic decisions eliminating guesswork and maximizing efficiency.
By using Seismic and the optimized frequency adjustments, the vibration powertrain and drum shells are exposed to less stress and wear compared to conventional compaction. This means a longer life of the vibratory system and related hydraulics. A less worn machine can stay in the fleet for longer or be sold at a higher resale value.
When vibrating at the natural frequency, the drum’s amplitude is optimized, which leads to a more efficient use of energy.
This ensures effective compaction with minimal energy as well as cost and fuel savings of up to 25 per cent when working together with EcoMode. The minimized fuel usage not only lowers operational costs but also translates to significant carbon dioxide reductions of up to 25 per cent and less environmental impact.
The Seismic Asphalt system is standard on all Dynapac heavy tandem rollers.
