The Automatic Standard Duty Single Marshall Compactor compacts Marshall specimens in a stationary 4in (102mm) mold. Automatic counter is set to the specified number of blows and stops at completion. The unit includes an oak pedestal with steel plate, a 10lb (4.5kg), 3-7/8in (98mm) diameter flat-face hammer, and a 4in mold, base and collar assembly.

The Marshall System is widely used for design and control of bituminous paving mixtures. The resistance to plastic flow of compacted cylindrical specimens is measured in terms of maximum load before fracture occurs. Standard 4" (102mm) diameter specimens are suitable for up to 1" (25.4mm) maximum aggregate size.

Four inch specimens are compacted with a 10 lb (4.54kg) hammer having 3-7/8" (98mm) circular face and 18" (457mm) free fall.

This Automatic Standard-Duty Single Marshall Compactor has a surcharge weight applied to the hammer foot during compaction. The weight is automatically lifted and released the exact number of hammer blows preset on the digital counter. Multiple automatic units permit duplicate compacting of check specimens under exact temperature conditions. They are also useful for mix design labs or labs with many test to run. Compaction Mold Assemblies, mold holders, hammers, counters, pedestals, and belt guards are provided with this mechanical compactor.
