Roller Compaction Production Rate
Surface coverage (sf/hr, sy/hr) and compacted cubic yards per hour a roller turns out from the drum width, speed, lift thickness, and passes - the production that sizes the fill schedule and the number of rollers. The test strip sets the passes.
Formula and source
area_sf_hr = drum_width x speed x 5280 x efficiency / passes; area_sy_hr = area_sf_hr / 9; production_ccy_hr = area_sf_hr x (lift/12) / 27 = 16.3 x width x speed x lift x efficiency / passes (16.3 = 5280 / (12 x 27)).
Roller production identity by name (compacted volume rate from coverage and lift); first-principles unit-folding arithmetic.
