Featuring a 2,000 mm wide drum with chamfer and radii drum edges, the DD128C offers the high compaction performance and reliability. This machine also features a large 1,400 mm diameter drum and auto-reversing eccentrics that ensure eccentric rotation in the direction the machine is traveling. It is also equipped with an industry-leading, automatic drum wetting system that provides speed-dependent water flow to minimize water usage and ensures uniform drum coverage to prevent material pick-up.

The DD128C has a wide range of amplitudes that allows for unmatched versatility whether the job is an ultra-thin lift or a deep 10 cm lift. The vibration frequency is automatically adjusted to the highest vpm for the amplitude setting so operators can get the high rolling speeds and productivity without compromise.

The DD128C is powered by an advanced 110 kW (148 hp) Volvo D4 Tier 4 Final engine, which delivers high torque at low rpm, ensuring high-quality performance with minimal noise and fuel consumption. Engine operating speed during work mode is a scant 1,850 rpm providing the torque and power needed without the noise and fuel draw. Fuel efficiency is further enhanced with optional auto-idling and auto-engine shutdown. The engine and hydraulics are designed to work together to provide quick start times and high drum performance in the most demanding conditions.

The DD128C compactor has unobstructed visibility along with many other advanced safety features. The ROPS/FOPS certified platform, all-around visibility, adjustable seat w/adjustable seat back and 180-degree rotating console provide visibility of the jobsite, as well as unobstructed sightlines to the mat for rolling precision. Ergonomically positioned controls, noise and vibration isolation, and space keep the operator alert and focused. Drum surface and spray nozzle visibility allow the operator to ensure consistent water flow and utilize the fully redundant backup system if a nozzle were to clog.

The DD128C’s swing-up hood allows for unobstructed access to the engine and hydraulic components, enabling simple maintenance, while a single key accesses all service doors. Passive regeneration occurs automatically, without requiring input from the operator, and a service regeneration is carried out by technicians as part of the routine 500-hour service. For added convenience, the water tank can be filled from ground level.

Equipping the DD128C with Compact Assist, Volvo’s unique Intelligent Compaction System, provides the operator with real-time feedback on compaction status. Pass mapping provides a clear view of where work has been done, and which areas require more attention. While temperature mapping ensures operators are compacting the asphalt before it cools. Compact Assist with Density Direct TM reveals the density of the mat in real-time. All the job data is stored and made available on the machine or over the air with job report summaries and data sets ready to be submitted.

The Impact Spacing Meter from Volvo provides a visual reference of speed control to maintain proper impact spacing, resulting in consistent smoothness. The DD128C can also limit machine speed to maintain proper impact spacing automatically making the roller operator’s job easier. With these features at their fingertips, operators can unlock the full productivity potential of Volvo compactors and ensure exceptional mat quality.
