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.

Water content (w) is the percentage of the weight of water to the weight of the dry solids. The term "moisture content" is sometimes used instead of "water content." A saturated soil has its voids completely filled with water, and its water content is denoted by w,,. Soil below the water table is usually considered to be saturated.
