The amount of water the stone will absorb (absorption rate) will help determine the resistance of the stone ...

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.
