Standard: ASTM D5581
Automatic Compactability
This ruggedly constructed apparatus automatically compacts the Marshall specimens 6” diameter, and stops after the preset number of blows has been completed on the separate automatic digital display counter.
The trip mechanism is structured so that the sliding hammer falls at the same height at every blow. The mould is stationary and the hammer has flat-foot.
