MS-52 Marshall Compactor utilizes a 4in stationary mold and delivers 64BPM to prepare hot mix asphalt specimens for Marshall stability and flow, specific gravity, and void content testing. These new compactors combine durability and efficiency with enhanced safety features for consistent, secure operation that produces accurate and reliable Marshall test specimens.
The mechanical compactors with stationary bases are available in 55 or 64 blows per minute (BPM) versions to compact 4in (101.6mm) diameter test specimens with a 10lb (4.6kg) flat-faced hammer. Gilson Mechanical Marshall Compactors are fully enclosed and incorporate heavy-duty construction with a 3/4hp electric motor that lifts the hammer to the precise height for each blow. They are equipped with an easy clamp mold securing system and a user-programmable electronic controller that can set blows between 1 and 999.
Real-time displays show both the current blow count and BPM. For enhanced efficiency, the controller automatically stops the hammer when the compaction process is complete, allowing the mold to be inverted for compaction on the opposite side and ensuring the same number of blows is applied for uniform specimen preparation.
Key safety features include a fully enclosed Marshall compactor that minimizes exposure to moving parts and a safety interlock system that prevents the compactor from operating unless the door is securely closed and latched, reducing the risk of injury. The machine also comes equipped with an emergency stop (E-Stop) button, which instantly cuts power in case of emergency, providing an extra layer of operator protection.
Each Gilson Mechanical Marshall Compactor includes an ASTM-compliant oak pedestal with steel plate, an all-stainless steel hammer assembly, a stationary compaction mold assembly, and Gilson’s exclusive easy clamp mold securing system. Order additional mold and hammer assemblies to preheat components for a more efficient workflow. Compactors operate on 115V, 60Hz power supply. Add an “F” suffix to the model number to specify 230V, 50Hz operation, or an “S” suffix to specify 240V, 60Hz operation.
