The Ammann ASC70D is a static smooth drum roller designed for efficient soil compaction across various soil types including clayey, loam, mixed, sandy soils, gravels, and stabilized soils. It features a 4.3 ft front drum diameter and a 66.2 in drum width equipped with steel scrapers to maintain drum surface cleanliness during compaction. The drum produces a high centrifugal force of approximately 32,600 lbs and a low centrifugal force near 29,200 lbs, with nominal amplitude at 0.1 in for both vibration settings, and vibration frequencies of 30 and 40 vpm for adaptable compaction energy. Static linear load is 133.9 pounds per inch, contributing to high compaction efficiency. Powered by a 101 hp (75 kW) B4.5-C99 engine, the roller has a maximum speed of 7.5 mph and a fuel capacity of 72.7 gallons, supporting extended operation. The machine stands 9.5 ft tall to the top of the cab, is 17.1 ft long, 6.2 ft wide, and has 15.2 in ground clearance. It weighs 15,741 lbs and uses 14.9-24 tires for traction and stability. The wheelbase measures 8.4 ft. With optimized vibration parameters for increased compaction effect and durability, the ASC70D offers reliable performance with minimal maintenance required, ideal for medium to heavy soil compaction in road construction and earthworks.
