Crushed Stone vs Crusher Run: Size, Cost, and Which to Use

Crushed Stone

Crushed stone is rock that a quarry blasted, crushed, and screened into a set size range. It costs $20 to $40 per ton in 2026, weighs 1.35 to 1.55 tons per cubic yard, and is the base under nearly every road, driveway, slab, and patio in the country. The important difference from "gravel" in the natural sense is shape: crushed stone is angular, so the pieces lock together, while natural river gravel is rounded and rolls. Almost everything sold as gravel at a quarry is crushed stone.

Crusher Run

Crusher run is crushed stone with the rock dust left in, sold as 3/4 inch minus or 1.5 inch minus. It costs $20 to $35 per ton in 2026, weighs 1.5 to 1.7 tons per cubic yard, and packs into a surface hard enough to drive on year after year. It is the standard base under roads, driveways, parking lots, and patios, and the best single-layer material for a gravel driveway. In the Southeast it is called crush and run. Highway departments call it aggregate base course, ABC, or Class 5.

Crushed Stone

• + Angular pieces interlock and carry weight
• + Cheapest bulk material at $20 to $40 per ton
• + A size for every job, from dust to 4-inch rock
• + Stocked at every quarry
• + Drains (clean) or packs (minus), your choice

• − Sharp edges, hard on bare feet and tires in big sizes
• − Plain gray look
• − Easy to order the wrong size
• − Larger sizes are hard to spread by hand

Crusher Run

• + Packs into a hard, drivable surface
• + Cheapest processed stone at $20 to $35 per ton
• + One layer does the whole driveway on firm ground
• + Grades smooth and repairs easily
• + Stocked at every quarry

• − Does not drain, sheds water instead
• − Dusty when dry, muddy when wet before it seals
• − Dense, so a ton covers less area than clean stone
• − Wrong choice for any drainage use
• − Plain gray look

Crushed Stone

Crushed stone is sold by sieve size, from stone dust and #10 screenings (under 1/4 inch) through #8 (3/8 to 1/2 inch), #57 (3/4 to 1 inch), #4 (1 to 1.5 inches), #3 (1.5 to 2.5 inches), and #1 or #2 (2.5 to 4 inches). Every size is angular with fractured faces. Color follows the quarry: gray or blue-gray limestone, gray to pink granite, dark basalt, or tan sandstone and limestone in the South.

Crusher Run

Crusher run is everything that comes off the crusher below a set size, usually 3/4 inch minus or 1.5 inch minus: angular stone at the top of the range down to sand and rock dust. Roughly a third of the mix is fines. Color matches the quarry rock, typically gray limestone or gray to tan granite, and it lightens as the dust dries.
