The automatic compactor provides a fully automatic and uniform compaction of specified effort, thus ensuring repeatable test results and eliminating any operator fatigue during the tests.  Conforming to ASTM and AASHTO Standards, this microprocessor-controlled soil compaction tester is designed for 4" and 6" moulds. The end of each layer compaction is indicated by a visual and acoustic signal. 
The machine is supplied  complete with all relevant accessories as: 50.8 mm circular face for 4" diameter specimen and inerchangeable sector face (triangular face) for 6" diameter specimens, and a rammer weights (2495/4535 g) that are easily interchangeable according to the reference standard. 
The wide control display and panel are connected with a shock absorber system and can be tilted according to user comfort.
The software gives the possibility to program customized sequences allowing the user to set the rotation angle from 5° to 90° with 5° steps between two subsequent blows, granting a precise and uniform blows distribution. 
The rotating base has screw clamping system for the moulds locking.
Two doors, one blind frontal and one transparent lateral, ensure comfortable access to a wide test area and gives free view during test running.
