Standard: EN 13286-47 / BS 1377:4 / ASTM D698, D1557, D1183 / AASTHO T99, T108, T193

Description: This machine automatically compact specimens, eliminating the laborious hand compaction method. The height and weight of the rammer are adjustable to suit test requirements. The rammer travels across the mould and the table rotates the mould in equal steps on a base that is extremely stable, the table also pushes forward and pulls back the mould. Compaction cycle: the mould is pushed forward and rotated, getting six blows at the side in different directions; then pulled back and got one blow in the middle. The number of blows per layer can be set at the beginning of the test.
