Best Types of Gravel for Driveways
A durable gravel driveway is built in layers: large stone (#3 or similar) on soft ground, a compacted crusher run base, and a top layer of #57 crushed stone or crusher run. Pea gravel is comfortable underfoot but shifts under tires.
Common gravel types
| Gravel | Size | Best for | Approx. tons per cu yd |
|---|---|---|---|
| #3 stone | 1–2 in | Bottom layer of new driveways, drainage | 1.3–1.4 |
| #57 stone | ¾–1 in | Driveway top layer, drainage, under sheds | 1.35 |
| Crusher run (road base, ABC) | Up to ¾ in with fines | Compacted base for driveways and pavers | 1.4–1.5 |
| Pea gravel | ¼–⅜ in, rounded | Paths, play areas, patios | 1.4 |
| River rock | 1–3 in, rounded | Decorative beds, dry creeks | 1.3 |
Names and sizes vary by region and quarry — "#57" is a standard ASTM gradation, but crusher run goes by many local names. Ask your supplier for their weight per cubic yard.
Building a gravel driveway
- Remove topsoil and grade with a crown so water runs off.
- Lay geotextile fabric on soft or clay soils.
- Add 4–6 inches of large stone if the ground is soft, then compact.
- Add 4 inches of crusher run and compact in lifts.
- Finish with 2–3 inches of #57 or crusher run.
