Digital programmable automatic Proctor/CBR compactor.

This research model is substantially similar to the standard model except for the more sophisticated compaction technique, which features all methods of the standard models plus the performance of the central blow prescribed by the French NF and Dutch RAV standards. At the start of the test cycle the operator selects the Standard (ASTM, NF, etc.) and the mould size and the test automatically proceeds. The display shows the current state of the test in real time. The end of each layer compaction is indicated by a visual and acoustic signal.
