W. Langer, in Sustainability of Construction Materials (Second Edition), 2016 9.3 Substitutes and manufactured aggregates. Crushed stone can generally substitute for sand and gravel, and vice versa. There are only a few naturally occurring materials that have the properties necessary to make an in-kind replacement for aggregate.

Colloquially, the term gravel is often used to describe a mixture of different size pieces of stone mixed with sand and possibly some clay. The American construction industry distinguishes between gravel (a natural material) and crushed stone (produced artificially by mechanical crushing of rock.). The technical definition of gravel varies by region and by area of application.

Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

This was due to the natural gravels developing lower aggregate voids as compared to the crushed stone mixtures having the same gradation. Significant increases in stability have been reported by Wedding and Gaynor (5) when using crushed gravel in place of natural gravel.
