Which equipment is recommended for sandy soils?

• A. Gyratory Compactor
• B. Rammer - Jumping Jack
• C. Reversible Plate Compactor
• D. Forward Plate Compactors or Static Rollers

Answer: (D)

For sandy soils, the goal is to densify granular material with equipment that provides steady, controlled energy over the surface. Forward plate compactors and static rollers fit that need well. A forward plate compactor delivers consistent vibration and downward force as you move in one direction, which helps rearrange sand particles evenly and achieve uniform density across the area. A static roller relies on mass rather than vibration, pressing the sand to reduce voids without the aggressive impact that can cause segregation or over-working fines. In contrast, a lab gyratory compactor isn’t field equipment, so it isn’t used on-site. A rammer or jumping jack applies sharp impacts that are more suited to cohesive, clayey soils and can cause uneven compaction or segregation in sands. A reversible plate compactor is a type of plate compactor, but for sandy soils the recommended approach is the forward method or static rolling to obtain uniform density efficiently.
