Dynapac’s CP28 is the world’s heaviest pneumatic tire roller.
The machine’s ballast weight allows contractors to choose a working weight from 10.5 to 31 tons, to meet job site requirements. The versatile roller is ideal for many applications, such as proof rolling soil and base, mainline asphalt compaction and chip sealing.
The CP28 features a flexible ballast system with three watertight compartments. Steel plates can be added or removed from ballast compartments using forklifts.
For enhanced weight flexibility, the machine can be ballasted with other materials like wet sand, water or steel. This flexibility allows contractors to optimize the machine weight from 10.5 tons to an industry leading maximum weight of up to 31 tons.
Precision operator control
Dynapac’s CP28 is equipped with a redesigned air-on-the-run (AOR) and tire suspension systems for greater control and uniform compaction. The AOR system allows precise tire pressure control to offer ideal wheel load weight for any application and can inflate all tires from low to fully inflated in 12 minutes.
Dynapac also built the CP28 with a newly designed front and rear suspension system to help optimize tires to surface contact. The front suspension includes a 4.5-degree lateral oscillation and a 1.5-degree tire tilt. The new rear suspension offers a 2-degree tire tilt to both sides.

As well, enhanced suspension movement helps maintain tire contact with the surface, leaving the operator with an impressive compaction result.
Each tire is equipped with its own water nozzle, cocoa mat and scraper as a standard feature. Options such as an independent emulsion spray system combined with Dyn@guard emulsion solution and tire skirts to help trap heat on the tires to limit asphalt pick up on the job site.
Fatigue-free operation
Like other machines in the Dynapac heavy tandem roller line, the CP28 roller’s standard features include a fully adjustable swivel and slide seat, 18-cm colour touch screen, harmonized controls across asphalt product line and premium operator station.
The CP28 can be customized with an asymmetric cab, allowing operators to achieve great visibility while remaining inside the cab for enhanced control.
The frame design is carefully crafted to achieve superior visibility in both front and rear of the machine allowing the operator to control the machine precisely for asphalt or chipseal compaction applications.
The CP28 pneumatic roller is also designed with sustainability in mind, including fully adjustable eco mode to minimize environmental impact. This feature maintains the lowest possible rpm while ensuring sufficient power is available for compaction.
The efficient water system includes Automatic Water Control (AWC), using water only when needed.
