Field performance report: ARR 1585-2 in real construction conditions

Loading...

The ARR 1585-2 trench roller demonstrates strong performance, reliability, and efficiency under real-world construction conditions. Equipped with a Kubota D1105 Stage V engine delivering 15.6 kW and an operating weight of 1,420 kg, the machine is designed to handle a wide range of compaction tasks across various soil types.

Materials tested

During the field test, the ARR 1585-2 was used to compact multiple types of materials, including:

  • Recycled construction waste, brick fraction 0/63 mm

  • Recycled construction waste, concrete fraction 0/63 mm

  • Gravel 16/32

  • Clayed sand and soil

This variety provided a comprehensive evaluation of the machine’s versatility across both granular and cohesive materials.

Test overview

The testing took place on a construction site during groundwork preparation for a family house. The machine was evaluated in two main phases: construction of an access road and compaction of a former basement excavation.

1. Access road compaction

The first phase involved building a temporary access road to allow heavy construction machinery to reach the site.

  • Total area: 260 m²

  • Material: 15–20 cm layer of recycled brick, 0/63 mm

  • Compaction: 5 passes over the entire surface

  • Total compaction time: approximately 4.2 hours

After compaction with the trench roller, the surface was leveled using a vibratory plate.

Result

The ARR 1585-2 proved effective in achieving consistent compaction across a relatively large surface area, maintaining surface integrity without material displacement during lane transitions.

2. Former basement compaction

The second phase focused on filling and compacting an excavated basement area to prepare for concrete foundation strip installation.

  • Excavation cleaned and prepared to required depth

  • Sequential layering and compaction process applied

  • 30 cm concrete rubble layer, 6 m², compacted with 10 passes

  • Two layers of gravel, 16/32 mm, each 15 cm thick

  • Final backfill: five layers of clay and clayey sand, each 20 cm thick

  • Total passes: approximately 30

  • Total compaction time: approximately 2.2 hours

Result

The machine handled both coarse and cohesive materials efficiently, delivering stable and uniform compaction even in confined excavation conditions.

Machine performance and handling

The ARR 1585-2 demonstrated several key strengths during operation:

  • Reliable and safe control, ensuring operator confidence

  • Skid-steering system allows smooth maneuvering even without damaging the compacted surface

  • Suitable for larger areas, not only trenches

  • Effective slope capability, easily exiting excavations

  • Lateral tilt warning system operates reliably, enhancing safety

  • Equipped with ACE, Ammann Compaction Expert, system for real-time compaction measurement

Fuel efficiency

Fuel consumption was monitored throughout the test:

  • Total operation time: 6.9 machine hours, mth

  • Fuel consumption: approximately 24 liters

  • Average consumption: 3.5 l/mth

  • Fuel tank capacity: 22 liters

  • Continuous operation without refueling: approximately 6 hours
