MS-56 Marshall Compactor utilizes a 6in rotating mold and delivers 64BPM to prepare hot mix asphalt specimens for Marshall stability and flow, specific gravity, and void content testing. These durable and efficient compactors have enhanced safety features and produce accurate Marshall test specimens.
Mechanical compactors with rotating bases use 22.5lb (10.2kg) bevel-faced hammers to prepare 6in (152.4mm) diameter specimens at 64BPM. MS-56 models can easily convert to compact 4in samples with the optional 4in Marshall Conversion Kit.
These heavy-duty units are powered by a 3/4hp electric motor that lifts the hammer to the precise height for each blow. They are equipped with Gilson’s exclusive easy clamp mold security system and a user-programmable controller that can set blows between 1 and 999. Real-time displays show the current blow count and BMP throughout testing.
To produce uniform sample preparation, the controller automatically stops the hammer when the compaction process is complete, allowing the mold to be inverted for compaction on the opposite site and ensuring the same number of blows is applied.
The compactor is fully enclosed to minimize exposure to moving parts. A safety interlock system prevents operation unless the compactor door is securely closed and latched to reduce the risk of injury. The machine is also equipped with an emergency stop (E-stop) button as an added layer of protection, which instantly cuts power in case of an emergency.
Each Gilson Mechanical Marshall Compactor includes an ASTM-compliant oak pedestal with steel plate, an all-stainless steel hammer assembly, a rotating compaction mold assembly, and Gilson’s easy clamp mold securing system. Order additional mold and hammer assemblies to preheat components for a more efficient workflow. Compactors operate on 120V, 60Hz power supply. Add an “F” suffix to the model number to specify 230V, 50Hz operation, or an “S” suffix to specify 230V, 60Hz operation.
