A 10×20 gravel driveway pad provides parking for one vehicle and is one of the most affordable driveway solutions. At 4 inches deep, you need about 2.5 cubic yards or 3.5 tons of gravel — typically a single delivery load.
Three-Layer System (Recommended)
For a durable driveway, use three gravel layers:
- Base layer (2"): #3 crushed stone (1–2" diameter) provides drainage and stability. ~1.2 yards.
- Middle layer (1.5"): #57 stone (3/4–1" diameter) fills gaps and locks the base. ~0.9 yards.
- Top layer (1.5"): #411 or crusher run (3/8" with fines) packs tight for a smooth driving surface. ~0.9 yards.
Cost Estimate
| Layer | Tons | Cost (2026) |
|---|---|---|
| #3 crushed stone | 1.6 tons | $32–$56 |
| #57 stone | 1.2 tons | $30–$48 |
| Crusher run (top) | 1.2 tons | $30–$48 |
| Delivery (1 trip) | — | $50–$80 |
Total: $140–$230. Compare to concrete ($1,500+) or asphalt ($800+) for the same area.
Pro Tips
- Excavate 4–6 inches and compact the soil before adding gravel. This prevents the gravel from sinking into soft ground over time.
- Install landscape fabric between soil and gravel to prevent mixing — a cheap step that extends driveway life by years.
- Top off annually. Gravel driveways need 0.5–1 cubic yard of fresh top stone each year to maintain depth and fill ruts.
