Crushed stone
Crushed stone is rock that's been broken and screened into sizes. The pieces are angular, so they lock together instead of rolling underfoot. That's why it's what most people end up using for driveways, drains, and anything that needs to hold its shape.
Below is every family we track, from dust-fine screenings to armor stone you can barely lift. Some of it we deliver. The rest is here so you can tell what you're being quoted.

How to choose within crushed stone
Compaction over drainage
Angular pieces lock together. Pick a smaller size when you need the surface to stay put under a driveway or path.
Drainage over compaction
The larger the piece, the more room for water to move through. #1 or #57 for a French drain; #8 or smaller reads as loose gravel.
Washed vs. unwashed
Washed has the dust rinsed out, so it drains faster and won't track into the house. Unwashed compacts harder — better under a paver base.
