Aggregate is the general name for a mixture of crushed stone, gravel, and sand.
Gravel can be composed of varying sizes of stone, sand, and fine dust, with the coarse stone measuring up to about 2 inches. Large stone is often referred to as ballast or sometimes, pit run. Even larger stone (6" to 24") is called rip-rap. Rip-rap is used to armor the soil to prevent erosion from water runoff. If you are using boulders or rip-rap, then gravel would probably be considered a fine aggregate. But if you are using gravel under a new sidewalk, say, then gravel would be somewhat coarse compared to the sand and fine dust in it.
