General The computation of earthwork volumes requires knowledge of basic geometry—summarized in mensuration charts. It also requires some knowledge of the behavior of soils upon being excavated from their in situ condition. For soils that must be compacted to a certain specified state, it is important to specify that state quantitatively in terms of a "percent compaction," which relates the desired in place unit weight and water content to the optimum water content and dry density, as reported by the Proctor test. Some soils also go through a phenomenon called bulking during handling and transportation. If this is significant, the go…
