The weight of the sample depends on the maximum particle size of the material being inspected. As a rule, a larger top size material the larger the sample. A 25 lb sample of No. 2 coarse aggregate would not be as representative of the material as a 25 lb sample of natural sand. TWO IMPORTANT DEFINITIONS TO REMEMBER

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.
