The Complete Guide to Crushed Stone and Gravel

Nov 11, 2019 · 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.

Gravel - Wikipedia

The definition of gravel varies by region and by area of application. Many geologists define gravel simply as loose rounded rock particles over 2 millimeters (0.079 in) in diameter, without specifying an upper size limit. Gravel is sometimes distinguished from rubble, which is loose rock particles in the same size range but angular in shape. The Udden-Wentworth scale, widely used by geologists in the US, defines granular gravel as particles with a size of 2 to 4 millimeters (0.079 to 0.157 in) and pebble gravel as particles wit

Crushed Stone Aggregates - Lehigh Hanson, Inc.

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further
