Direct answer
Calculate crushed-rock volume from a measured footprint and specified depth. Because the term varies regionally, retain the exact supplier product description with the result.
The calculator can support paths, base layers and general groundworks when crushed rock is the named material. Use separate calculations for layers with different gradings.
Measure between completed restraints or formation edges. For widened turning areas or irregular paths, split the footprint into rectangles and triangles and add the volumes.
In some markets crushed rock overlaps with crushed stone; in others it denotes a particular base product. The title alone cannot establish equivalence.
A path consists of a 9 m × 1.0 m rectangle plus a triangular widening with 2.4 m base and 1.5 m perpendicular height. Area is 9 + (2.4 × 1.5 ÷ 2) = 10.8 m². At 70 mm, volume is 0.756 m³.
The example uses geometry only. It does not insert a density, package size, recommended depth or supplier tolerance.
Ask what grading, maximum particle size and fines content the local “crushed rock” description represents. Confirm sale unit and material condition.
No load capacity, compaction response or suitability is inferred. Volume does not guarantee the delivered quantity after placement.
Users and suppliers use both terms differently. Separate pages explain that ambiguity rather than claiming equivalence.
Yes, provided you understand whether it describes the placed, compacted or loose layer.
