Tonnage that accounts for compaction — the part everyone forgets.
The classic road base mistake: you calculate compacted volume, order that many tons of loose aggregate, and come up 25% short after the plate compactor does its job. This calculator builds the compaction factor in, converts to tons using the right density for crushed stone, recycled base, or hot-mix asphalt, and adds delivery if you need it.
Rural homeowners and contractors pricing driveways use it because tonnage-with-compaction is where base orders go 25% short. The material toggle (crushed vs recycled vs asphalt) matters because densities — and prices — differ enough to change the order.
At 6 inches compacted: 50 × 12 × 0.5 ft = 300 cu ft = 11.1 compacted yards ≈ 15.5 tons of crushed stone, or about 19.5 tons ordered loose after the 25% compaction factor.
Yes for driveways and rural lanes — millings re-bind under compaction and summer heat, resist dust, and usually cost less per ton than virgin crushed stone. They are not DOT-approved for public roads and can track indoors in hot weather.
