The Automatic Marshall compactor has been designed to simulate hand compaction as described in ASTM D1559. This apparatus automatically compacts the sample and stops after a preset number of blows has been completed. The Compactor gives Uniformly and accurately compacted marshal moulds for reliable testing.
Vertex Automatic Marshall compactor machine is designed to provide a stable and rigid mechanism for producing 4″ & 6″ diameter asphalt pills used in Marshall tests.
The Marshall compaction machines are available in two types of configurations: one with a rotating mold with a tapered foot hammer assembly, and the other a stationary mold with a flat-foot hammer. Both models feature a heavy-duty design, which stands up well to the constant jarring caused by the compaction process.
These machines feature an automatic counter that allows the operator to present the number fo blows wanted and will turn off the machine when completed. After the number of blows has been set, the operator can start the machine with push-button and keep track of the number of blows on an LED readout. A cam-action lever operates the integral mold holder to facilitate the insertion and removal of the compaction mould.
