Technical Description
The Volvo DD15 is a compact static smooth drum roller designed for efficient compaction of hot mix asphalt, soil sub-base, and aggregate base layers. It features a 39.4 in (1,000 mm) wide smooth drum with a 22 in (560 mm) diameter and a 0.47 in (12 mm) shell thickness, providing a professional finish with chamfered drum edges. The roller delivers a high vibration frequency of 66.7 vpm (66.7 Hz) and a centrifugal force of 3,507 lbf (15.6 kN), enabling high-speed, high-productivity compaction comparable to larger machines. Power is supplied by a Kubota D722-B Tier IV diesel engine, a 3-cylinder, water-cooled, naturally aspirated unit producing 16.4 hp (12.2 kW) at 3,000 rpm, coupled with a hydrostatic transmission for smooth, stepless speed control. The DD15 has an operating weight of 3,372 lb (1,530 kg), an operating width of 40.1 in (1,019 mm), and overall dimensions of 80.1 in (2,035 mm) in length and 40.1 in (1,019 mm) in width, with a height of 88.2 in (2,240 mm) when equipped with ROPS. It offers a travel speed of up to 3.9 mph (6.3 km/h) and an outside turning radius of 108 in (2.74 m), ensuring excellent maneuverability in confined spaces. The machine includes an isolated vibratory drum system to minimize vibration feedback, an industry-leading rust-proof water spray system, and an easy-access engine compartment for simplified maintenance.
