What is also known as a backfill tamper?

• A. Plate compactor
• B. Rammer
• C. Sheepsfoot roller
• D. Vibrator

Answer: (B)

Backfill tamping relies on delivering repeated blows to compact soil in confined spaces, rather than using vibration. The tool designed for this method is the rammer, which provides high-impact, low-amplitude blows to the soil with a heavy foot or platen. This makes it ideal for trench backfills and around utilities where space is limited. Plate compactors use vibration to densify larger, typically granular soils over bigger areas, a shearfoot roller kneads soil with feet for cohesive soils on wide areas, and a vibrator is a general term for devices that vibrate to aid compaction. Thus, the backfill tamper is best identified as a rammer.
