Subbase and base materials can usually be distinguished visually from the noted characteristics. You need to be able to distinguish them so that you can know if the right thicknesses were employed as required by the design.

Base course may be well-graded with smaller max. size of rock (<1"), particularly true if the final road surface is gravel.
