ABSTRACT:
An apparatus for monitoring soil compaction using a compaction machine which applies periodic impact blows to the soil surface. The apparatus comprising a rotatable, multi-sided compactor mass that applies periodic impact blows to the soil surface when rolled over that surface. Data related to the level of compaction of the soil surface is derived, during compaction of the soil surface, from the deceleration of the compactor mass as it impacts the soil surface. This is achieved using one or more accelerometers mounted on the impact compactor.
