Marshall Compactor – Automatic ASTM


Automatic Marshall Compactors are designed to provide a stable and rigid mechanism to be used for preparation of bituminous specimens for Marshall Stability tests.

TAS-0782A model Compactor is for compaction of 4” dia. specimens and TAS-0784A model Compactor is for 6”dia. specimens.
Both models feature a heavy-duty design, which stands up well to the constant jarring caused by the compaction process.

The compactors are equipped with a hand operated mould fixing mechanism which locks the mould in place during compaction and reduces vibration of the mould.

The conveniently positioned control panel comprises of start/stop button, emergency stop button and a direct reading counter used to set the required number of blows. The operator can keep track of the number of blows on an LCD display.

The apparatus stops automatically after the preset number of blows.

The moulds have to be ordered separately.

The standard models can be supplied with a safety/noise reduction cabinet. The cabinet is lined internally with soundproofing material to reduce sound level conforming to CE directives
