#57 Gravel vs Crushed Limestone: Size, Cost, and Which to Use

#57 Gravel

The 57 comes from the ASTM C33 grading table. Size #57 means most of the stone passes a 1-inch screen and stays on a #4 sieve (about 3/16 inch), with the bulk of it between 1/2 and 1 inch. It is "clean" stone, so there are no fines. That leaves about 35 percent air space in a pile, which is why it drains so well and why it stays loose on its own.

Crushed Limestone

Crushed limestone is quarried limestone that has been crushed and screened into standard sizes from screenings to 3-inch rock. It costs $20 to $45 per ton in 2026, weighs 1.3 to 1.5 tons per cubic yard, and is the cheapest crushed stone across the Midwest, Texas, Florida, Pennsylvania, and any other region sitting on limestone bedrock. Its light color, low price, and the way its fines cement together under traffic make it the default driveway and road gravel in a big part of the country.

#57 Gravel

• + Cheapest useful stone at $20 to $35 per ton
• + Stocked at every quarry in the country
• + Drains fast, about 35 percent void space
• + Angular pieces interlock under load
• + Works for driveways, drains, concrete, and backfill

• − Too coarse to walk on comfortably
• − Stays loose, rolls to the edges under tires
• − Needs a finer top layer on driveways
• − Not decorative

Crushed Limestone

• + Cheapest crushed stone in the Midwest, Texas, and Florida
• + Fines cement together into a hard surface
• + Light color brightens driveways and beds
• + Every standard size available
• + Packs harder than granite crusher run

• − White dust in dry weather
• − Raises soil pH, bad for acid-loving plants
• − Softer, breaks down faster under heavy trucks
• − Expensive where it has to be trucked far

#57 Gravel

#57 gravel is angular crushed stone screened to 3/4 inch to 1 inch, with a few pieces down to 1/2 inch. Color depends on the quarry: gray or blue-gray limestone through the Midwest and Northeast, gray, white, and pink granite in the Southeast, tan limestone in Texas, and dark basalt in the Northwest.

Crushed Limestone

Crushed limestone comes in every standard sieve size: screenings under 1/4 inch, #8 (3/8 to 1/2 inch), #57 (3/4 to 1 inch), #4 (1 to 1.5 inch), #2 (2 to 3 inch), and crusher run (3/4 or 1.5 inch minus). It is angular when fresh and wears smoother than granite. Color runs white, cream, light gray, and tan, and it turns bright white as dust dries on the surface.
