SettingsSettings for this calculationUS
The total roadway surface area to be covered with base course.
Measure the area to be covered by the aggregate base course layer, excluding areas outside the roadway prism.
The compacted thickness of the base course layer.
Depth is set by the pavement design (e.g. AASHTO structural number analysis) for the expected traffic loading and subgrade conditions.
The compacted in-place density of the base course aggregate.
Typical compacted crushed stone base course density is around 1900-2200 kg/m³, but confirm with the actual material's test data where available.

How this was calculated
Formula source(s)
- Mass = area × depth × material density, converted to metric tons, the standard method for estimating bulk aggregate base course material
Inputs used
- Roadway Area
- 10760 sq ft
- Base Course Depth
- 6 in
- Material Density
- 124.86 pcf
Intermediate steps
- Volume
- 199.26 yd³
What this calculation does not cover
- Covers the neat prism only, area times depth. A base course is normally laid wider than the surfacing it carries, running past the edge of asphalt and then falling away on a batter, and that widening is real tonnage — take the area off the paved width alone and the order is short by the shoulder on every load.
- The density asked for is the compacted in-place figure; the ticket at the weighbridge is wet weight. Aggregate leaves the pit carrying free moisture, a few percent by mass in normal weather and appreciably more after rain, so the mass bought and the mass placed are two different numbers and the difference is water you paid for.
- Nothing here allows for stone lost into the subgrade. A soft or pumping formation swallows part of the first lift as the roller works it, and the material that disappears below the design line still came off a truck — on weak ground the order needs an over-excavation allowance, or a separation geotextile to stop the loss.
