The function of the pavement subbase is to provide drainage and stability to achieve longer service life of the pavement. Most pavement structures now incorporate subsurface layers, part of whose function is to drain away excess water that can be deleterious to the life of the pavement (see Section 6G-1 - Subsurface Drainage Systems).

When stones are run through a crushing machine to make crushed stone, stone dust also forms. Its exact composition will depend on what kind of stone ran through the machine, such as granite or limestone. The machine has a screen that traps the larger crushed stone and lets the smaller material (or "screenings") fall through the screen.

Crusher fines in their purest form have no soil mixed in, they are pure crushed stone. Gravel and crusher fines differ from one another in that gravel is screened to remove the fines which contain the natural binders/cements. Gravels remain loose because of dead air or pore space within the matrix which allow them to drain well and …
