The quality of granite is judged from how far the resulting value of the density of crushed stone is from the density of granite - 2.7 g / cm3 (or 2.7 kg / dm3). Too different from the "granite" value of the absolute density suggests that the crushed stone is not made of granite at all, but, say, basalt or, in general, secondary.

For aggregates, density is determined by multiplying the relative density (specific gravity) of the aggregate times the density of water. Bulk Density of Aggregate [1] The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that is required to fill a container of a specified unit volume. Bulk Density = Mass / volume

Crushed stone varies in size. The number "57" is a number that refers to the size sieve that was used to screen and sort the stone. It means that the stone was put through the #57 sieve which produces gravel stones of about 1" to 1.5" in size. #1 crushed stone refers to the largest sized crushed stone. It is about 2″ to 4″ in size.

In simple terms, when we say a soil sample has achieved 95% compaction, it means that the compacted soil has reached 95% of its maximum possible dry density as determined by a Proctor test. Proctor testing is a test performed in the laboratory that compares the density of a soil sample to various moisture contents.
