Approximate weight

13.5 short tons

High confidence

About 1.35 short tons per cubic yard for dense-graded crushed limestone; dust content and gradation shift this either way. A planning figure, not a specification. Confirm the actual density with your supplier before ordering by weight.

Conversion factor applied
1.35 short tons per cu yd

Crushed limestone is the workhorse sub-base material across much of North America, specified as a compacted thickness and sold by the ton. The conversion has to account for the fact that dense-graded material is designed to compact hard: the loose yardage that arrives is meaningfully more than the yardage that ends up in place, because the fines migrate into the voids under a roller. Ordering against the compacted requirement without allowing for that loss leaves the sub-base under specification, which shows up years later as settlement rather than immediately as a shortfall.

Add the equipment this sizes

This result is a specification — 13.5 short tons — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

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.

Frequently asked questions

Why does limestone compact so much?
Because dense grading is designed for it. The range of particle sizes lets fines fill the voids between larger stones under compaction, producing a dense interlocked layer. That is what makes it a good sub-base, and it is why loose volume exceeds in-place volume.
Is crusher run the same thing?
Broadly, crusher run describes unscreened material straight from the crusher including its dust, which is dense-graded by nature. Named products vary regionally, so confirm the gradation rather than relying on the name.
How thick should a sub-base be?
It depends on the subgrade and the loading, and it should come from a design rather than a rule of thumb. Soft ground needs more, and geotextile separation is often more effective than extra depth.
