How much gravel for a 100-foot driveway, 12 feet wide?

Data checked October 2026

Short answer

A new 12×100 ft driveway built as 4 in of #57 stone under 4 in of compacted crusher run takes about 53.4 tons of stone: 22 t of #57 stone and 31.4 t of crusher run, with 10% extra.

Base: 1,200 sq ft × 4 in = 14.81 cu yd; with 10% extra order 16.3 cu yd ≈ 22 tons of #57 stone.
Top: 14.81 cu yd compacted needs 21.67 cu yd loose (1.33× for compaction, plus 10%) ≈ 31.4 tons of crusher run. Spread about 5.3 in and compact in 2 lifts.
Trucks: 2 tandem loads of #57 stone and 2 tandem loads of crusher run — separate stones travel as separate loads.
Bulk cost at the default prices: about $2,201 delivered ($1,140 + $1,061, $75 per load).
Lay 1,200 sq ft of woven geotextile first, and crown the finished surface 1/2–3/4 in per foot (Penn State).
A 100 ft run is a full truck-and-a-half job: order both stones from one yard and stage deliveries so the base can be compacted first.

What's it for?

Project

A typical new driveway: 4 in of #57 base stone on fabric, topped with 4 in of compacted crusher run. Penn State's road spec places 8 in loose to finish at 6 in.

Compacted bases for driveways, sheds, slabs and pavers. Stone plus fines packs hard — the default base material. Also sold as: crush & run, #411, 304, DGA, ABC, GAB, CA-6, 21A, 2A, flex base, Class 2 AB, 3/4 minus.

* finished depth after compaction

Order loose, finish compacted

Spread about 5.3 in of crusher run and compact it in 2 lifts of no more than 3 in to finish at 4 in. That is why the order is 1.33× the finished volume — bag labels and most calculators skip this and leave you short.

Weight factors vary by quarry

Crusher run / #411 / road base: 1.45 t per loose cu yd (published 1.3–1.62).#57 stone / clean crushed stone (3/4 in): 1.35 t per loose cu yd (published 1.3–1.65).Your yard's scale ticket is the final word — enter its factor under “Weight factor”.

Pickup payload

Payload is on the Tire & Loading sticker in the driver's door jamb. Single-axle dump trucks carry about 5 tons; bigger orders come on a tandem (up to 18 tons).

Crown it

Shape the surface with a crown or cross-slope of 1/2–3/4 in per foot so water runs off instead of soaking the base (Penn State Center for Dirt & Gravel Roads).

Layer by layer for a 12×100 ft driveway

Layer	Depth	Order (cu yd)	Tons	0.5 cu ft bags	Bulk delivered
#57 stone	4 in	16.3	22	880	$1,140
crusher run	4 in compacted	21.67	31.4	1,171	$1,061

How this was worked out

The base layer of clean #57 stone drains and spreads the load; the top layer of crusher run has fines that lock together under compaction into a hard driving surface. Penn State's road specification places 8 in loose to finish at 6 in, which is where the 1.33× compaction factor comes from.

At 53.4 tons this job needs more than one tandem load; ask the yard to dump the base stone first, then return with the crusher run once the base is spread and rolled.
