A correction factor is applied to roadway earthwork volume calculations when the alignment includes a horizontal curve to account for the eccentricity of the curved area.
A correction factor to compensate for soil shrinkage is applied to volume calculations to represent the volume of material in a "natural state" that is required to fill compacted roadway embankments. Additionally, a swell compensation factor may be required if rock or large stones are transferred from their natural state to a constructed embankment.
