Automatic Marshall Impact Compactor, Rotating, ASTM

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 6in Marshall Compactor Hammer Assembly (Heavy-Duty) and  6in Marshall Compaction Mold Set, available separately, convert this model to compact 6in samples.
