Marshall Mechanical Compactor Set
| ASTM
D 1559 The Marshall Single and Double 4 in Mechanical Compactor Set is used for mechanical compaction of asphalt samples for Marshall testing. 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. Lift and release mechanism on hammer weight ensures uniform impact on hammer foot. Constant surcharge weight is maintained on hammer foot during compaction, and face of hammer foot is held squarely against specimen at all times. The Mechanical Compactor Set is available as a single or double compactor unit. Both are supplied complete with pedestal as required by ASTM.
