It’s used when compacted the subgrade and base coarse if I recall correctly. So if used correctly, it will help the construction crew account for the variability of the natural materials (earth foundations with high void ratios; subgrade; and base coarse) that typically cause uneven compaction and potholes. I don’t believe it’s used when compacting the surface coarse
