construction - How much volume is lost after compacting 3

A standard specification for careful tamping of backfill is "in 6-inch lifts to 95% of maximum density". In other words, after tamping, there is still a potential for 0% - 5% potential volume loss. The 74% packing density is "face-centered cubic" or "hexagonal close pack" or "tetragonal body-centered cubic".

TEST METHOD FOR EARTHWORK COMPACTION CONTROL BY NUCLEAR GAUGE

To evaluate the field density, it is must be compared to a control density. The control density is expressed in terms of the dry density of the minus ¾ in. (19 mm) portion of the material. The method of determining the control density is described in Section 5.2. The field density, Line H, is in total wet density units.

Standard Weights for Crushed Rock Per Meter | Hunker

Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.
