how do you increase the compaction of sandy soil?

• A. Water
• B. Water and vibration
• C. Vibratory
• D. Steel roller

Answer: (B)

Compaction of sandy soil is most effective when you combine the right moisture with dynamic energy to move and rearrange the grains. Water at the optimum level reduces inter-particle friction and helps grains slide into a tighter packing, but water alone won’t compact a dry sand. Vibrations provide the energy needed to overcome remaining friction and to rearrange particles into a denser arrangement. So using moisture at the right level together with vibration yields the highest dry density for sands. A static method like a steel roller relies mainly on pressure and is generally less effective on sands than vibratory compaction, especially when moisture is involved.
