Overview

The Ammann AV 70-2, 85-2, 95-2, and 115-2 series are heavy tandem rollers designed primarily for asphalt compaction but also suitable for compacting gravel, sand, and stabilized soils. These machines are ideal for medium to large surface areas such as highways, roads, construction sites, and industrial zones.

Key Features and Specifications

• Chassis and Maneuverability: Rigid chassis with split drums (billes fendues) allowing optimal energy transmission and excellent maneuverability, including crab steering with lateral offset up to 1293-1340 mm on both sides.
• Drum and Vibration: Two vibrating drums provide effective compaction with selectable frequencies and amplitudes to suit various surface types. The split drum design prevents surface rippling.
• Operator Comfort and Control: Spacious cabin with dual-side access, sliding and 170° rotating seat with integrated controls, and fingertip steering (FTS) allowing three steering modes (front drum, rear drum, or both). An LCD screen displays steering mode, drum angle, crab offset, vibration frequency, machine speed, and engine RPM.
• Engine and Power: Equipped with Cummins engines (4BT3.3-C85 for AV70-2 to AV95-2 and QSB4.5-30-T-C110 for AV115-2) delivering 63 kW or 82 kW respectively, compliant with ISO 3046/1 standards.
• Water and Fuel Capacity: Water tanks range from 600 to 1300 liters for drum wetting; fuel tanks range from 125 to 210 liters depending on model.
• Braking System: Hydrostatic service brakes with multi-disc parking and emergency brakes.
• Dimensions and Weight: Operating weights vary from approximately 6,650 kg to 11,550 kg; maximum compaction widths range from 2,583 mm to 3,090 mm.

Variants

• Standard Tandem Rollers: AV 70-2, 85-2, 95-2, 115-2 models with split vibrating drums.
• Combi Models (AV70-2K, AV85-2K, AV95-2K): Combine a vibrating front drum with pneumatic rear tires for enhanced surface homogenization.

Options and Accessories

• ACE (Ammann Compaction Expert) system with infrared thermometer for intelligent compaction control and continuous amplitude/frequency adjustment.
• Cutting and compacting discs controlled from the cabin with water spray nozzles.
• Gravel spreader and sand distributor with vibrator.
• Infrared temperature sensor with dashboard display.
• Cabin options including canopy with ROPS, air conditioning, radio, additional work lights, beacon, and vandalism protection.
• Safety and convenience features such as reversing alarm, fire extinguisher, tool kit, and biodegradable hydraulic oil.

Ergonomics and Operator Benefits

The fingertip steering system combined with the sliding and rotating seat allows the operator to maintain optimal posture and visibility during all phases of operation, reducing fatigue and improving compaction quality. The ergonomic layout places all controls within easy reach, enhancing precision and comfort.

Maintenance and Durability

• Robust articulation bearings and high-quality hydraulic oil filtration ensure long service life.
• Maintenance intervals are set at every three months and two years for major servicing.
• Reliable vibration eccentric mechanisms.
