Which statement describes the finishing method after tamping a lift to achieve the final surface?

• A. Rolling with a Pneumatic or Smooth-Drum Roller
• B. Sprinkling water to wet the surface
• C. Adding more material
• D. Excavating and replacing the layer

Answer: (A)

After tamping a lift, finishing the surface is done by rolling with a Pneumatic-tire or smooth-drum roller. Rolling densifies and smooths the surface, closing remaining voids and bringing the layer to the required density and grade for a stable, uniform finish. Watering is used during compaction to achieve the right moisture, not as the finishing step. Adding material or excavating and replacing would alter thickness or require repair rather than provide the final finish.
