What Size Gravel for Driveway?

A well-built gravel driveway uses three layers of progressively smaller stone: Base Layer (4 inches) Use #3 stone (1-2 inches) or #4 stone (1.5-3 inches). These large angular stones create a stable foundation and won't sink into soft soil. A geotextile fabric under this layer prevents the stone from migrating into the subgrade. Middle Layer (4 inches) #57 stone (3/4 to 1 inch) is the standard choice. It fills the gaps in the base layer, adds stability, and provides a transition to the finer top layer. Top Layer (2-3 inches) #8 gravel (3/8 to 1/2 inch) or crushed limestone creates a smooth driving surface. Some homeowners prefer #411 (a blend of #57 stone and stone dust) because the dust fills voids and compacts into a very firm surface. What to Avoid Avoid using pea gravel or river rock for driveways — their rounded shape means they never lock together and will constantly shift under tires, creating ruts.

#57 Gravel vs Recycled Asphalt

Side-by-side comparison of #57 Gravel and Recycled Asphalt to help you choose the right gravel for your project.

Overview

#57 Gravel

Crushed stone approximately 3/4 to 1 inch in size. One of the most versatile and commonly used gravel sizes in both residential and commercial construction. #57 stone is the go-to aggregate for drainage, driveways, and concrete production.

Recycled Asphalt

Recycled asphalt is made from reclaimed asphalt pavement that has been crushed and screened. When compacted, it hardens over time as residual asphalt binder reactivates, creating a durable and cost-effective driving surface.

Common Uses

#57 Gravel

✓ Driveways
✓ Drainage
✓ Concrete mix
✓ Pipe bedding
✓ Backfill
✓ Parking areas

Recycled Asphalt

✓ Driveways
✓ Parking areas
✓ Rural roads
✓ Access roads

Pros & Cons

#57 Gravel

+ Extremely versatile — works for many applications
+ Excellent drainage characteristics
+ Good compaction when combined with fines
+ Widely available nationwide
+ Cost-effective

− Too coarse for comfortable walking
− Angular edges
− Shifts under foot traffic without stabilization
− Requires a finer top layer for driveways
− Not decorative

Recycled Asphalt

+ Very affordable
+ Compacts into a hard surface
+ Less dust than gravel
+ Reuses existing materials

− Can soften in extreme heat
− Dark color absorbs heat
− Limited availability in some regions

Cost Comparison

Measure	#57 Gravel	Recycled Asphalt
Per ton	$20 – $35	$15 – $30
Per cubic yard	$25 – $45	$20 – $45

Sizes & Colors

#57 Gravel

#57 gravel consists of angular crushed stone pieces ranging from 3/4" to 1" in diameter. Color depends on the quarry source — typically gray, blue-gray, or brown. The stones are angular and irregular, which helps them interlock.

Recycled Asphalt

Crushed asphalt pieces typically under 1 inch. Black or dark gray in color.
