Automatic Compactor

Product Details:

The Automatic Bitumen Compactor is designed to perform fast and accurate compaction of soil samples automatically acc. to ASTM and AASHTO standards. For standard or modified compaction tests with 5.5 lb. hammer with 12” (305 mm) height of drop or 10 lb. hammer with 18” (457 mm) drop. Compactor accommodates 4” (102 mm) or 6” (152 mm) I.D. moulds, 4” (102 mm) round hammer or 6” (152 mm) pie-shaped hammer compensate for sample drop during compaction. The total weight of the hammer is concentrated at the foot in order to provide a free-fall action. Hammers can easily be replaced from the front side of the compactor.

Machine stops automatically after preset number of blows per compaction is completed. Compaction mould is mounted on the round base; the circular base indexes automatically with each blow to ensure uniform sample compaction. A pie-shaped compactor foot is used with 6” (152 mm) dia. moulds to completely cover the surface of the sample.

A compaction pedestal with specimen holder is fixed to the base.

Product Details:

The rammer assembly is provided with a ratchet and pawl arrangement to lift it from the top of the soil layer. When the rammer reaches the required height the pawl release the rammer which falls freely on soil surface. The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter fitted to the compactor is used to set the number of blows. The base plate of the specimen mould is to be fitted to the rotating base plate of the instrument which marks.
