11 Cubic Yards of Road Base in Tons

11 cubic yards of road base in tons works out to about 16.5 tons using a planning weight of 1.5 tons per yard. Real loads land between roughly 15.4 and 18.1 tons depending on stone size, fines and moisture. That is about 33,000 pounds.

The conversion

  • Yards × tons per yard: 11 × 1.5 = 16.5 tons.
  • Low end: 11 × 1.4 = 15.4 tons.
  • High end: 11 × 1.65 = 18.1 tons.

Quarries can tell you the weight per yard for their own product; use it if you have it.

About road base

Road base is meant to be compacted at close to the right moisture. Dry base rock does not lock up well; a light spray of water before rolling helps.

Hauling 11 yards

At about 16.5 tons, this is more than one typical truckload. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.

Before you order

  • Confirm whether the yard prices road base by the ton or by the yard.
  • Add about 10 percent for compaction and uneven ground.
  • Clear a firm spot for the truck to dump.

The volume and tonnage calculator converts any area and depth into yards and tons.

When to choose road base

Best suited to:

  • Base under asphalt and concrete
  • Gravel roads and drives
  • Equipment and shed pads

Think twice for:

  • Drainage layers
  • Decorative surfaces
  • Surfaces that will stay uncompacted

Quick reference numbers

  • Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.6 tons.
  • Another size for comparison: a 10x20 area at 2 inches takes about 1.9 tons.
  • Weight used here: about 1.5 tons per cubic yard.

Mistakes that throw off the order

  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.

Either works; just convert with the supplier’s own weight per yard so the two quotes compare fairly.
