How Much Asphalt Millings for a 10x30 Driveway?
A 10 by 30 foot driveway is 300 square feet. How much asphalt millings for a 10x30 driveway depends on depth: at 4 inches it is about 3.70 cubic yards or 4.8 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 10x30 driveway
- Area: 10 × 30 = 300 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 300 × 0.333 = 100.0 cu ft.
- Cubic yards: ÷ 27 = 3.70 yd³.
- Tons: × 1.3 = 4.8 tons.
The volume and tonnage calculator does this for any size.
Asphalt millings needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

About asphalt millings
Millings vary by source: some loads are fine and uniform, others carry chunks. Ask the supplier for a screened product if you want a smoother finish, and check local rules, since some areas restrict their use near water. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
Preparing the driveway
Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 5.3 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the driveway as firm ground allows.
Good and poor uses for asphalt millings
Best suited to:
- Rural driveways and farm lanes
- Parking areas where a dust-free surface is wanted
- Low-cost base under a future paved surface
Think twice for:
- Areas near wells or streams where local rules limit them
- Decorative or barefoot areas
- Jobs needing a uniform, clean look
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of asphalt millings (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 14x28 area at 3 inches takes about 4.7 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
