Marshall Mechanical Compactor Set

Mechanical compaction reduces inaccuracies involved in hand compaction and eliminates much of the work.

This set includes an automatic counter unit for pre-selecting the number of hammer blows, after which the unit will automatically shut off. The lift and release mechanism on the hammer weight ensures uniform impact on the hammer foot. A constant surcharge weight is maintained on the hammer foot during compaction, and the face of the hammer foot is held squarely against the specimen at all times.

Compactors can be ordered as single or double units, and are supplied with a beveled hammer face and rotating base or with a flat hammer face and a non-rotating base. Compactors will accommodate hammers for either 4 or 6-inch diameter molds, and a change-over can be accomplished in a matter of minutes. A pedestal, as required by ASTM, is included with the compactor.
