  DENSITY TESTING AND INSPECTION MANUAL

  Compaction is the elimination of excess air spaces (voids) in a soil by mechanical means. Vibration is a good mechanical means in sand soils; compression and impact are more successful means of compaction in clay soil. Some common types of equipment used for compaction on sand are tracktype dozers, vibrating rollers, wobblewheel rollers and ...
