The Hand-Operated Shaker is used for field testing. The Spring Type Hand Shaker conforms to ASTM, AASHTO and California test methods. It has a cylinder mounting bracket suspended by two steel straps. The operator manually oscillates the cylinder with steel traps to a preset mark on the case. A digital counter records the strokes. Components are mounted on a textured, vinyl-covered, plywood carrying case. The removable case front has latches and a top handle.
Dimensions: (W x D x H): 24 x 6 x 25 in (610 x 152 x 635 mm)
The Hand-Operated Shaker is also used in the Durability Index Test which measures the relative resistance of an aggregate to produce undesirable clay-like fines when subjected to certain mechanical methods of degradation.
