The Volvo DD-22 and DD-24 (pictured) double-drum asphalt compactors are designed for light- and medium-duty applications.

The DD-22 features a drum width of 39 inches and an operating weight of 5,400 pounds. The DD-24 has a drum width of 47 inches and an operating weight of 5,725 pounds. The front and rear drums on both compactors protrude beyond the frame, making it easier to compact around obstructions without the chassis getting in the way and giving operators a clear view of drum edges.

“The footprint of the machines provides the operator with excellent all-around visibility, including the drum edges,” says Anand Chaturvedi, marketing manager, soil compaction for Volvo Construction Equipment.

The DD-22 and DD-24 double-drum units are built to produce the right combination of amplitude, centrifugal force and frequency to maximize daily productivity. Both compactors provide the choice of automatic or manual vibration and can operate in three modes: statically, front drum vibration only or both drums vibrating. Two vibrating frequencies — 3,300 or 4,020 vibrations per minute — allow the DD-22 and DD-24 to produce smooth, dense mats with a reduced number of passes. At 4,020 vibrations per minute, these compactors have the highest frequency in their class, according to the company.
