Automatic Marshall Compactor, Astm
This ruggedly constructed machine has been designed to eliminate the laborious process of hand compaction.
The apparatus automatically compacts the sample and stops after the preset number of blows.
The mould is held in position by a quick and practical clamping device. The trip mechanism is arranged so that the sliding hammer falls at the same distance for every blow. The compactor includes the laminate hardwood block.
All moving parts are protected with safety guard, which stops automatically the compactor when opened, and the control panel is fit with an emergency stop red button.
There are 2 models designed for 4” and 6” dia. Marshall molds.
In the model for 4” dia. Marshall molds, The drive mechanism lifts the 4536 g ± 9 gr compaction hammer, plated against corrosion, to the height of 457mm ± 3 mm allows free fall.
In the model for 6” dia. Marshall molds, The drive mechanism lifts the 10205 g ± 10 gr compaction hammer, plated against corrosion, to the height of 457mm ± 3 mm allows free fall.
