For tamping foot compaction, what speed is used during the walking-out phase after the initial passes?

• A. 3-5 mph
• B. 2-4 mph
• C. 8-10 mph
• D. 5-7 mph

Answer: (C)

In tamping foot compaction, the finishing or walking-out phase is all about smoothing and distributing the surface finish after the initial passes. Moving at a brisk pace around 8–10 mph helps sweep across the area, reducing the visibility of patterns left by the early passes and promoting a more uniform density and surface texture. If you go much slower, you’re overworking the top layer and can create ridges or uneven spots because the same area gets compacted repeatedly. A faster, consistent walking-out pace also helps cover the surface evenly before final shaping and testing.
