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

UTAS-0782A Compactor for compaction of 4” dia. specimens features 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 compactors apply a speed of 64±4  blows per minute to Ø4” specimens .And also 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 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

UTAS-0667 Marshall Steel Blocks which can be used for initial heating of the foot of compaction hammer and Marshall moulds should be ordered separately.
