SOIL COMPACTION- A REVIEW OF EQUIPMENT AND TECHNIQUES

FOR COMPACTION PURPOSES, SOILS ARE CLASSIFIED INTO THE FOLLOWING THREE BROAD GROUPS: SAND AND SILT (GRANULAR), SANDY LOAM AND SILT LOAM (COHESIVE), AND CLAY (COHESIVE). SOIL COMPACTION IS THE CONSOLIDATION OF DISTURBED SOIL BY APPLIED MECHANICAL ENERGY. THE DENSITY OF THE SOIL IS INCREASED BY A PROCESS OF VIBRATING TAMPING, OR ROLLING. COMPACTION IS AIMED PRIMARILY AT REMOVING AIR VOIDS. MOISTURE CONTENT IS THE MOST IMPORTANT FACTOR IN EFFICIENT SOIL COMPACTION. MOISTURE ACTS AS A LUBRICANT WHICH HELPS PARTICLES TO MOVE CLOSE TOGETHER UNDER THE COMPACTIVE EFFORT. THE ACTION IS DISCUSSED OF THE FOLLOWING COMPACTORS: TAMPERS, IMPACTORS OR RAMMERS, STATIC COMPACTORS, VIBRATORY COMPACTORS AND ROLLERS. COMPACTION WITH WATER JETS AND VIBRATION HAVE PROVED IDEAL FOR USE WITH DEEP, GRANULAR SOILS.
