Compaction technology can have a significant impact on your bottom line. Utilising technology can help you eliminate passes and deliver substantial savings in labor, fuel and machine wear. The technology also can ensure compaction goals have been achieved, eliminating the need for costly re-work at the jobsite.



Technology is not new to the road-building industry. But if you look back, and then forward, you’ll realise we’re in the midst of a technological revolution that will benefit those who embrace the changes – and leave behind those who don’t.




The patented Ammann triple-shaft exciter system provides industry-leading climbing ability and compaction output. It ultimately delivers outstanding results, even on cohesive soils.

The triple-shaft exciter system eliminates erratic movements, allowing smooth travel even through heavy, cohesive soil. The unique system’s consistent movement enables effortless climbing over obstacles or while compacting backfill materials with high moisture content. This is done without the usual suction effect, which can leave plates at a standstill.

The ease in handling and manoeuvering of the plate is particularly helpful when the use of low frequency/high amplitude is required.



The unique advantages of the well-known Ammann Compaction Expert (ACE) system for optimal compaction control are now featured on Ammann vibrating plates. ACE can display and measure the degree of compaction for jobsite efficiencies and quality control purposes.

Mode of operation
The vibrations generated by the exciter shafts are detected by sensors on the base plate, which transfer acceleration data and the relative positions of the exciters to a site control system. This patented control system, which is vibration-isolated and displayed on the handle, ensures the machine continuously operates at maximum performance. This is supported by highly efficient compaction control with the tested fully hydrostatic system – a standard feature on all heavy-duty Ammann vibrating plates.


Oscillation eliminates about 90 per cent of the stress on materials when compared with a traditional circular vibratory system. This is important when compacting on bridges, over sewers and utility lines and near buildings where a traditional vibratory approach can cause damage.

Oscillation uses less force but delivers both vertical and horizontal energy, essentially massaging the aggregates into place. The drums maintain constant contact with the ground and deliver both static and dynamic forces.

Compactors with oscillation can bring substantial benefits to jobsites. In asphalt applications, they are able to work on hot mats sooner than traditional rollers, and they are able to stay on cold mats longer, too. This greatly expands the compaction window, essential for time-pressed crews.

The rollers also are great fits for sealing asphalt joints. The massaging motion of oscillation provides enough energy to break down the hot asphalt – yet does not damage the adjacent cold mat.

When working in soil applications, the compactors prevent damage to sensitive structures and over-compaction.



Precise, transparent and verifiable compaction processes increasingly are required on construction sites. Ammann took the first steps toward providing these processes in 1998 with the advent of Ammann Compaction Expert (ACE), an automated compaction measurement and control system.

ACE has been continually improved since its introduction and remains the industry leader. It is the only system that automatically adjusts amplitude and frequency based on ground characteristics.

The benefits of ACE technology are significant. Among them:

  1. It can reduce the number of passes a roller makes and deliver savings on fuel, labor and machine wear.
  2. ACE helps ensure proper compaction is achieved and prevents costly rework, which in some cases can even require a return to the jobsite.
  3. It extends the life of the compacted material – and structures placed on top of it – by providing a homogenous surface without weak spots.

ACE technology is available for both soil and asphalt applications. There are three ACE options available.


  • For use with single-drum and heavy asphalt rollers
  • Provides compaction measurement, automatic control and a documentation system
  • Precisely measures and evaluates material stiffness
  • Continuously adjusts frequency and amplitude depending on compaction measurements
  • Delivers the highest compaction efficiency by sending optimal force into the ground
  • Eliminates drum jumping and therefore minimizes the risk of over-compaction or material destruction
  • Includes ADS documentation software with office analyzing feature
  • Can utilise all major manufacturers’ GPS products to provide mapping and operator guidance


  • For use with single-drum rollers, light and heavy asphalt rollers and vibratory plates
  • Provides measurement and documentation

  • Includes ADS documentation software with office analyzing feature
  • Can utilise all major manufacturers’ GPS products to provide mapping and operator guidance


  • For use with vibratory plates
  • Relative compaction measuring device
  • Continuous information about compaction levels
  • Evaluates when maximum compaction has been reached


ACEecon is a proprietary compaction system from Ammann that provides accurate, real-time data to operators of light equipment.

ACEecon continuously measures compaction progress and communicates that information to the operator via an LED display on top of the machine.

That information is extremely valuable for the operator – and ultimately profitable for the contractor – because it removes guesswork from the compaction equation.

Without ACEecon, the operator must estimate the compaction level. If the operator overestimates compaction, he might depart prematurely and leave unfinished work behind. This can lead to quality control issues and costly rework.

Productivity and profits also can be lost if the operator underestimates the progress and continues to work after compaction has been achieved. This miscalculation leads to wasted labor and fuel, and also puts unnecessary hours on the machine.



ACEplus combines the ACE (Ammann Compaction Expert) measurement and control system with a navigation system. It provides an efficient analysis and documentation system for continuous compaction control (CCC).

The satellite navigation system accurately assigns the measured compaction values to the position coordinates and the time. The graphic display of measurement data relays the on-site compaction work and enables a fast and reliable performance analysis.

ACEplus therefore increases process reliability and integrates quality control measures in the work process.
