Porosity and Bulk Density of Sedimentary Rocks - USGS
pubs.usgs.govdensity-bulk density relation was 25.5 percent where bulk volume was determined by the displacement of water by a previously wetted specimen, but 24.6 percent where bulk volume was determined by mercury displacement. Steinhoff and Mell (1924), using 73 cubes of porous refractory material 2 em along the edges, found that the
METHOD OF TEST FOR RELATIVE COMPACTION OF …
dot.ca.govThis test method describes the procedure used to determine the relative compaction of untreated and treated soils and aggregates. Relative compaction in this method is defined as the ratio of the in-place, wet density of a soil or aggregate to the test maximum wet density of the same soil or aggregate when compacted by a specific test method.

DENSITY OF ASPHALT CONCRETE - HOW MUCH IS NEEDED?
wipp.energy.govdensity requirements and the methods of measuring density vary considerably from state to state.Some states construct a control test strip, measure the density on the strip, and use that density as the target density for the project. Other states compact samples in the laboratory during mix design and
