Base course aggregate needed

330.69 tons

High confidence
Volume
196.19 yd³

For the dimensions entered, expect a base course aggregate needed of 300 metric tons. Note that roadway area sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. Set for United States against IRC 2024. The market selector changes both the units and the code cited.

Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

  • Mass = area × depth × material density, converted to metric tons, the standard method for estimating bulk aggregate base course material

Frequently asked questions

Why convert to metric tons instead of just giving mass in kg?
Aggregate base course is typically ordered and priced by the metric ton (or short ton), so converting the computed mass to tons matches how suppliers quote and deliver bulk material.
What density should I use for the base course material?
Compacted crushed stone base course is commonly around 1900-2200 kg/m³, but the actual in-place compacted density varies by gradation and compaction effort — use test data for your specific material where available.
Does this account for compaction shrinkage from loose delivered material to compacted in-place volume?
No — this calculates the mass needed to fill the specified compacted volume (area × depth) directly. If you are ordering loose (uncompacted) material by volume, you will need to add a compaction/shrinkage allowance separately.
