The math for a 14x120 driveway

  1. Area: 14 × 120 = 1,680 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 1,680 × 0.333 = 560.0 cu ft.
  4. Cubic yards: ÷ 27 = 20.74 yd³.
  5. Tons: × 1.3 = 27.0 tons.

About recycled concrete aggregate

Recycled concrete aggregate is crushed old concrete. It compacts well and often costs less than virgin stone, which makes it a common driveway and pad base. Weight per yard is a planning number; the scale ticket at the yard is the real one.

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. 29.7 tons may take more than one 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.

When to choose recycled concrete aggregate

Best suited to:

  • Driveway and pad bases
  • Temporary construction entrances
  • Fill under slabs when compacted in lifts

Less suited to:

  • 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 10x20 area at 4 inches takes about 3.2 tons.
  • Weight used here: about 1.3 tons per cubic yard.

Common estimating mistakes

  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
