This material has a 1-1/2 inch top size and is a clean material. Often used for backfill for retaining walls, used for subase for sheds, also sometimes used as driveway stone. Also used as the primary raw aggregate in Ready Mixed Concrete and some Hot-Mixed Asphalt mixes. Will not compact.

Sieve analysis - Wikipedia

A suitable sieve size for the aggregate underneath the nest of sieves to collect the aggregate that passes through the smallest. The entire nest is then agitated, and the material whose diameter is smaller than the mesh opening pass through the sieves. After the aggregate reaches the pan, the amount of material retained in each sieve is then weighed.
