Material in the truck settles 10-15% as it compacts. If you buy only for the measured depth, the completed base can end up half an inch short. This calculator therefore starts with a +10% allowance. You may see this material called Bank Run Gravel, pit gravel, gravel borrow in Vermont, or 2 inch minus on tickets. These names refer to crushed stone containing fines, about 3,000 lb per cubic yard, which compacts into a tire-resistant surface.

Calculate for finished depth

  1. Find the footprint in feet: multiply lane length by width, or measure the pad sides.
  2. Enter the finished compacted depth: 4 inches for paths and pavers, 4-6 for driveways, and 6-8 for trucks.
  3. Convert cubic feet / 27 = yards, then x 1.5 = tons. Leave the +10% selected. Specifications apply after rolling.
Tons = (Area sq ft × Compacted depth in ÷ 12) ÷ 27 × 1.5 × 1.10

Uses and limits

  • For driveway bases, compact 4-6 inches, then add 2-3 inches of #57 or driveway gravel as the driving surface.
  • For low-cost rural lanes, crusher run can form the driving surface. Plan on summer dust and regrading every 2-4 years.
  • Paver and slab bases need 4 inches installed in 2-inch compacted lifts. The Paver Base Calculator covers the complete paver stack.
  • Sugarhouse and barn pads need 4 inches over stripped ground, or 6 on soft soil.
  • Keep it out of French drains. Its binding fines retain water, while drainage calls for clean #57 or drain rock.

Example: a 20 x 10 parking pad

For 200 square feet compacted to 4 inches, 200 x 0.333 = 67 cubic feet = 2.5 cubic yards, or 3.7 tons. With allowance, order 4 tons. Place and compact the first half, then repeat with the remaining material. Building in two 2-inch lifts lasts years longer than placing one 4-inch layer, especially through deep frost and freeze-thaw cycling.

Delivery details

  • Schedule base and surface stone together in one delivery. Delivery is free either way, and the project can keep moving.
  • Start with the pile tipped at the outer end of the run, then spread back toward it. On large pads, working downhill can save a full day.
  • Before compacting, lightly wet each lift. Damp crusher run binds tighter than dry material.
  • Hold back a wheelbarrow-load for repairs. Use the remaining crusher run to patch potholes as they develop.

Pricing approach

Crusher run is produced without the washing and sorting used for other stone. On a 4-ton order, the +10% allowance may avoid a separate half-ton delivery. See the Crusher Run product page for the per-ton price, compare Road Base, and order both driveway layers in one free delivery.

Crusher run, Bank Run Gravel, pit gravel, gravel borrow: common questions

How much crusher run is needed for a driveway?
For mud-season lanes, allow a 4-6 inch compacted layer. The estimate converts volume at 1.5 tons per yard and includes 10%. For a 50 x 10 ft lane finished at 4 inches, plan on roughly 10 tons delivered.
What does a yard of crusher run weigh?
One cubic yard weighs about 3,000 lb, or 1.5 tons, with slightly more weight after rain. Fines fill the voids between stones, adding weight compared with clean gravel.
How do crusher run and gravel differ?
Crusher run contains stone dust, while products such as #57 are screened clean. The dust binds into a hard base. Clean stone remains loose for drainage and surface layers. A driveway uses them in that order.
Are crush and run and crusher run identical?
These are regional names for the same material family. Bank Run Gravel, pit gravel, gravel borrow, and 2 inch minus identify the same blend. Ordering under any of those names brings that blend.
Can crusher run serve as a finished surface?
Yes, for rural and low-traffic drives. It creates a firm running surface, but dry weather brings dust and it needs regrading every few years. A later 2 inches of #57 addresses both.
What amount does crusher run compact?
Plan for ten to fifteen percent. A 4-inch loose layer compacts to roughly 3.5 inches. The calculator turns on its allowance by default for that reason, and specifications use compacted depth.
