Compare with bags
You need 13.5 cubic yards of compacted crushed stone base ≈ 22.8–24.6 tons (compacted in place).
Buying by the yard? Stone is delivered loose and packs down: order about 17–19 yd³ loose for 13.5 yd³ compacted, or order the tons shown.

Gravel driveway depth from road guides
Gravel driveway depth has no published residential standard: no DOT or extension source sets a driveway base and top layer. The closest guidance comes from gravel road and farm lane manuals.
| Source | Written for | Depth |
|---|---|---|
| FHWA | Gravel roads: surface layer | 3 in minimum |
| FHWA | Gravel roads: layers | over 4 in total → separate layers, each ≥ 2× top stone size |
| Penn State DSA | Low-volume roads: surface course | 6–8 in loose → 4½–6 in compacted |
| USDA-NRCS | Farm travel lanes: aggregate pad | 3 in fine over a coarse base, or 6 in single layer |
Sources: FHWA Gravel Roads guide (2015); Penn State DSA Handbook (2025); NRCS TN 210-AEN-04 (2017). Penn State compacts with a 10-ton roller; a plate compactor packs less.
Gravel driveway base: loose vs compacted weight
Gravel driveway base weighs about 25–60% more per yard compacted than loose crushed stone. Pick the compacted option and order the tons it gives, or the loose yards it lists; ordering the compacted yards as loose stone comes up short.
| Material | lb per yd³ | tons per yd³ | Bags | $ per yd³ |
|---|---|---|---|---|
| Crushed stone | 2,600–2,700 | 1.3–1.35 | Bulk only | $35–$54 |
| Crushed stone base (compacted)* | 3,375–3,645 | 1.69–1.82 | Bulk only | — |
| Gravel | 2,550–2,850 | 1.28–1.43 | 0.5 cu ft (50 lb) | $15–$75 |
Weight basis: crushed stone loose, as delivered; crushed stone base (compacted) compacted in place; gravel dry, loose. * Estimate: supplier data or one source only.

Gravel driveway worked example: 60 × 12 ft

Gravel driveway FAQ
- How thick should a gravel driveway be?
- No DOT or extension source publishes a residential gravel driveway thickness. Road guides call for a 3 in minimum surface layer (FHWA) and 6–8 in loose compacting to 4½–6 in (Penn State DSA).
- Should a gravel driveway go down in layers?
- Yes, gravel thicker than 4 in goes down in separate layers, each at least 2 times the top stone size (FHWA gravel road guide).
