Ammann develops new tandem drum asphalt compactors

Developed by Ammann, the new ARX 90 and ARX 110 tandem rollers are available in both Tier 4Final/Stage IV variants for use in Europe and North America, as well as Tier 3 versions for use in lesser regulated markets. These high performance units are the first Ammann vibratory rollers to feature oscillation. This system cuts out around 90% of the vibrations to surroundings from conventional vibratory systems.

ARX 90 = High performance unit
Developed by 6791 Ammann, the new ARX 90 and ARX 110 tandem rollers are available in both Tier 4Final/Stage IV variants for use in Europe and North America, as well as Tier 3 versions for use in lesser regulated markets. These high performance units are the first Ammann vibratory rollers to feature oscillation. This system cuts out around 90% of the vibrations to surroundings from conventional vibratory systems. The new rollers combine the oscillating, back-and-forth-movement of the drum with a constant static load. The firm claims that this allows the units to reach specified compaction values more quickly.

For increased output, the ARX offers a combination of oscillation and the firms heavy-duty, two-stage vibratory drum. This said to offer easy adjustment of amplitude and frequency. The optional ACE system offers measurement in absolute values and evaluation of material stiffness. It also provides an operator guidance function and can document the whole compaction process.
