The Ammann ASC150D is a high-performance static smooth drum roller designed for efficient soil compaction across various construction applications, including road, railway, airfield, and industrial site construction. It features a front smooth steel drum with a diameter of 59.1 inches and width of 86.7 inches, capable of exerting centrifugal forces of 53,280 lbs (high) and 73,063 lbs (low), with a nominal amplitude of 0.1 inches and vibration frequencies of 29 and 35 vibrations per minute. The roller delivers a static linear load of 259.9 pounds per inch for uniform compaction. Powered by a Cummins QSB4.5-C160 engine generating 158 hp (118 kW), the machine offers a fuel capacity of 108.4 gallons and a maximum speed of 6.3 mph (10 kph). It weighs approximately 31,703 lbs, providing stability and compaction efficiency. Ground clearance is 16.6 inches, with overall dimensions including a length of 18.7 feet, width of 8.3 feet, height of 10 feet, and a wheelbase of 9.3 feet. Equipped with 23.1-26 tires, the ASC150D supports maneuverability and durability on rough terrain. The articulated frame and smooth drum design enable effective compaction of a wide range of soils, including clay, loam, sandy, gravelly, and rockfill materials, with layer thicknesses varying by soil type. Its vibration and amplitude systems ensure optimal compaction outputs, and the unit typically includes operator comfort features such as adjustable seating and an ergonomically designed cabin. The ASC150D is suitable for medium to large compaction jobs requiring consistent and reliable performance.
