FAQ
What are swell and shrink factors (L/C)?
Soil expands when excavated (loose state, L) and shrinks when compacted (C). L is the loose-to-bank ratio and C the compacted-to-bank ratio. Common soil uses about L 1.20, C 0.90.
How do cut and fill differ?
For cut, the bank volume is excavated and hauled in loose state (×L). For fill, the compacted volume is the target, so required bank volume = compacted ÷ C, and haul volume = bank × L.
How are truck loads calculated?
Hauling is based on loose volume, divided by a 15 ㎥ dump truck and rounded up. Actual loads vary with fill ratio and truck size.
