How Much Recycled Concrete Aggregate for a 14x30 Driveway?
How much recycled concrete aggregate for a 14x30 driveway is a quick volume problem. 420 square feet at 4 inches comes to 5.19 cubic yards. Recycled concrete aggregate usually weighs about 1.2 to 1.4 tons per cubic yard, so plan on roughly 6.7 tons.
Volume and tonnage calculator →The math for a 14x30 driveway
- Area: 14 × 30 = 420 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 420 × 0.333 = 140.0 cu ft.
- Cubic yards: ÷ 27 = 5.19 yd³.
- Tons: × 1.3 = 6.7 tons.
The volume and tonnage calculator does this for any size.
Recycled concrete aggregate needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 3.89 | 5.1 | 5.6 |
| 4 in | 5.19 | 6.7 | 7.4 |
| 6 in | 7.78 | 10.1 | 11.1 |
About recycled concrete aggregate
Ask whether the recycled concrete has been screened for rebar and debris. Fresh-crushed concrete can also be alkaline, so keep it away from sensitive plantings and streams. 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. For car and truck traffic, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 7.4 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 recycled concrete aggregate
Works well for:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Poor fit for:
- Near ponds, streams or sensitive plants, since fresh crush can raise pH
- Decorative top layers
- Drainage layers, unless the product is clean and screened
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 15x30 area at 3 inches takes about 5.4 tons.
- Weight used here: about 1.3 tons per cubic yard.
Mistakes that throw off the order
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
