Aggregate weight moves with gradation, moisture and how hard it was compacted. These are published figures from a manufacturer engineering table and two supplier charts, not a measurement of your pile: the full citation for each row is printed on sheet C-101, where you can also type your supplier’s own number in. Materials with no figure in any open document — pea gravel, road base, decomposed granite, asphalt millings, riprap — are listed there without a default on purpose.
