"Dust" is just that-only the fines, without any crushed stone. GB is typically sold around here with either 3/4" minus stone or 1-1/2" minus stone mixed with dust I've always used graded base to dress up my drive, (as well as neighbors common drives) but I'm thinking, perhaps a top pass with just dust might provide for a smoother job.

Crusher Fines. Fines—sometimes called crusher fines —are small particles of crushed rock that include a mix of sizes, from a fine dust up to 3⁄8 inch (about 9.5 millimeters) in diameter. Often, crusher fines are leftovers from crushing operations, but they can be custom produced. Using crusher fines alone contributes to dusty conditions.
