Vibratory Asphalt Compactor DD90HF
The DD-90HF
features dual 66 inch (1675 mm) wide drums with 3800 vpm (63.3 Hz) frequency
for fast rolling speeds and ultra smooth surface finish. The unit provides
high performance capability for main line highway paving jobs. Operating
weight over 10 tons (9.8 metric tonnes) meets all state D.O.T. static
rolling requirements. The DD-90HF has a nominal capacity up to 325 tons (290
metric tonnes) of HMA per hour.
Standard Features
• Adjustable vibration on/off speeds of 0.75, 1.25, 1.75, 2 mph (1.2, 2,
2.8, 3.2 km/hr)
• Automatic reversing eccentric rotation
• Dual vibration frequency of 3800 vpm (63.3 Hz) and 2500 vpm (47.5 Hz)
• Eight-position variable amplitude settings

• Four-cylinder turbocharged and aftercooled diesel engine
• Machined drums, chamfered drum edges
• Polyethylene water tanks, 260 gallons (984 liters) capacity
• Patented Impact Meter to provide consistent spacing of drum vibration
impacts for uniform compaction of HMA
• Standard ROPS/ FOPS and seat belt
• Two complete, independent water systems with triple water filtration,
four water pumps, four spray bars and variable water flow
