Marshall Compactor, Automatic, Heavy-Duty Rotating 4in Mold compacts a 4in (102 mm) asphalt specimen into a rotating-base mold and can easily be adapted to compact 6in (152mm) samples with a Hammer Assembly, sold separately.
The heavy-duty frame reduces structural and mechanical wear and tear during operation. The tapered-foot hammer and rotating base plate produce a consistent kneading action during compaction. Molds are secured with a cam-action lever assembly, and an automatic counter shuts off the unit at the completion of the compaction process.
An ASTM-compliant oak pedestal with steel plate, automatic counter, 10lb (4.5kg) tapered-foot hammer, a package of paper discs, 4in mold, and base and collar assembly are included. The MSA-113 6in Marshall Compactor Hammer Assembly (Heavy-Duty) and MSA-106 6in Marshall Compaction Mold Assembly, available separately, convert the MS-5 models to compact 6in samples.
MS-5: 115V, 60Hz, 6 Amps
MS-5F: 230V, 50Hz, 4.5 Amps
