Intelligent control for all compaction applications

ACE (Ammann Compaction Expert) is an electronic measuring and control system for vibrating rollers that automatically adjusts the amplitude and frequency to suit the characteristics of the ground. The system has been available in larger Ammann machines for several years, helping operators to achieve target levels of compaction without over-compacting or loosening material. Ammann now offers the same technology for light compaction equipment, including its AVH 6030 model, a three-shaft high performance vibratory plate compactor, and its RW 1504HF trench roller.
ACE manages the machine’s compaction effort according to its reading of the layer’s load bearing capacity. The system automatically reduces the compactor amplitude in hard areas, and increases amplitude where load capacity is low. The operator is presented with a clear and simple display of machine and compaction data; including continuous readings for current amplitude and frequency. The display also provides the recommended speed for optimum compaction, so the operation can be completed accurately in the fewest possible passes.
Real-time information improves profitability by reducing the number of passes to achieve compaction targets, reducing the time and cost to complete the project, and eliminating over-compaction.
ACE can show where soft spots or uncompacted areas are located in the material so operators can improve the quality of the layer. As a result, ACE leads to a more homogenous compaction throughout the material, and ensures the uniform load-bearing capacity through all layers to provide an ideal base for asphalt.
For tandem rollers, ACE also ensures consistent compaction levels and bearing capacity and achieves an optimal surface structure. ACE is able to monitor the temperature of the asphalt and will prevent the machine from compacting if the mat is too hot or too cold. ACE also allows early identification of trouble spots beneath the surface, where the subsoil is not up to the required load bearing capacity.
The ACE system records all data on the bearing capacity of each soil or asphalt layer to meet requirements for CCC (Continuous Compaction Control) documentation. Captured data can be exported via standard USB storage devices. This record of continuous readings enables contractors to identify non-compactable areas and take any necessary remediation steps, such as soil stabilization or material exchange.
Ammann ACEplus includes new GPS technology which puts mapping of compaction results into the operator’s compartment through a touchscreen, among other benefits.
