Mass haul

The running total of cutting − filling along the chainage, with the cut factor (shrinkage or bulking) and the fill factor (compaction). Where the curve rises the work is in cutting, where it falls in filling; each loop between two balance points balances.

For each loop the table gives the volume, the average haul and – beyond the free haul – the overhaul. The end of the curve is the surplus to spoil (+) or the shortage from borrow (−).
