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.

COMPACTION TECHNOLOGY

COMPACTING WITH VIBRATORY PLATES

THE TRIPLE-SHAFT EXCITER SYSTEM

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.

 

ACE ON PLATE COMPACTORS

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.

ACEeco
With the ACEeco system comes the corresponding relative compaction control display. ACEeco continuously informs the operator about the degree of compaction and the maximum target.

ACEforce
ACEforce is mounted on the machine and covers the spectrum of compaction in soil and aggregate compaction. Available information includes the achieved compaction. The system also can automatically adjust based on the compaction level. This helps avoid unnecessary passes and possible over-compaction. The measurement mode allows compaction measurement at any point on-site.

Oscilação

A oscilação elimina cerca de 90 por cento do estresse em materiais quando comparada com um sistema vibratório circular tradicional. Isto é importante quando se compacta em pontes, sobre tubulações e linhas de serviços públicos e perto de edifícios, onde uma abordagem vibratória tradicional pode causar danos.

A oscilação utiliza menos força, mas proporciona energia vertical e horizontal, essencialmente massageando os agregados para a correta acomodação em seu lugar. Os tambores mantêm um contato constante com o solo e fornecem forças estáticas e dinâmicas.

As máquinas de compactação com oscilação podem trazer benefícios substanciais em seus locais de trabalho. Em aplicações de asfalto, elas são capazes de trabalhar com superfícies quentes mais cedo do que os rolos tradicionais, e elas também podem permanecer mais tempo em superfícies frias. Isso expande grandemente a janela de compactação, essencial para equipes pressionadas por tempo.

Os rolos também são ótimas soluções para selar juntas de asfalto. O movimento de massagem da oscilação fornece energia suficiente para quebrar o asfalto quente – mas não danifica a superfície fria adjacente.

Ao trabalhar em aplicações de solo, os compactadores evitam danos a estruturas sensíveis e excesso de compactação.

INTELLIGENT GROUND 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.

ACEpro

  • 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

ACEforce

  • For use with single-drum rollers, light and heavy asphalt rollers and vibratory plates
  • Provides measurement and documentation
  • Precisely measures and evaluates material stiffness
  • Operator guiding function shows compaction progress
  • Includes ADS documentation software with office analyzing feature
  • Can utilise all major manufacturers’ GPS products to provide mapping and operator guidance

ACEecon

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

ACEecon

O ACEecon é um sistema de compactação patenteado da Ammann que fornece dados precisos e em tempo real para operadores de equipamentos leves.

O ACEecon mede continuamente o progresso da compactação e comunica essas informações ao operador através de uma tela LED na parte superior da máquina.

Essa informação é extremamente valiosa para o operador – e, em última instância, é rentável para o empreiteiro – porque remove suposições da equação de compactação.

Sem o ACEecon, o operador deve estimar o nível de compactação. Se o operador superestimar a compactação, ele poderá parar prematuramente e deixar o trabalho inacabado. Isso pode levar a problemas de controle de qualidade e retrabalho caro.

A produtividade e os lucros também podem ser perdidos se o operador subestimar o progresso e continuar a trabalhar após a compactação ter sido alcançada. Este erro de cálculo leva ao desperdício de trabalho e combustível, e também coloca horas desnecessárias na máquina.

GPS-BASED COMPACTION

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.
