Each sand-cone and matched base plate will also have a set of unique cone corrections and bulk sand densities. If more than one sand-cone apparatus is available, the sand-cone and base plate should be marked and the associated correction/density factors recorded. Vibration of the sand during any mass-volume determination may increase bulk density of the sand

The dry density test is carried out in the field to check the compaction of the layers. Compaction is very useful for preparing the sub-base grade and other layers of pavement. Compaction is done in the construction of embankment to increase
