Answer :

Methods of field compaction of soil

i) Rolling- In this method, soil is compacted by using 6-8 tonne heavy rollers. The rollers are selected as per type of soil. Due to heavy weight, compression of soil takes place.

ii) Ramming or Tamping- In this method, soil is compacted by using suitable rammers or tampers. Rammers may be flat footed and tampers have spiny projection. It is done manually, which becomes time consuming.

iii) Vibration- In this method, soil gets compacted under vibrational energy produced by vibratory compactors. Vibrations of large amplitude, rearrange the soil particles together and hence overall compaction takes place.
