DD-90 Vibratory Asphalt Compactor
The DD-90 features dual 66 inch (1675 mm) wide drums and provides high performance capability for highway and other large paving jobs. Ten plus tons (9.1 metric tons) of static weight meet D.O.T. static rolling requirements for increased machine utilization. The DD-90 has a nominal capacity up to 250 tons (227 metric tons) of HMA per hour.
Standard Features
- Non corrosive polyethylene water tanks, 250 gallon (946 liters) capacity
- Impact spacing meter to provide consistent, uniform compaction of asphalt
- 3/4, 1-1/4, 1-3/4, or 2 mph automatic vibration speed settings
- Manual push button vibration control located on propulsion lever
- Two complete and independent water systems with four water pumps and water flow control
- Eight variable amplitude settings
- Five-position rotating operator’s console for excellent visibility
- Machined drum surfaces and chamfered drum edges
• Automatic reversing eccentrics
