Ammann has introduced the ACEeco compaction measuring system for its five model AVH hydraulic plate range. As an extra cost option, the system uses a compaction display that indicates the compaction progress using an LED scale. The system also displays the maximum compaction level achievable and this, said Ammann, will help operators to avoid making unnecessary passes and over-compaction. Available for AVH5020, 5030, 6020, 6030 and 100-20 models, which have operating weights from 530–555kg and working width
