#57 Gravel vs Bank Run Gravel: 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.

Bank Run Gravel

Bank run gravel is a naturally occurring mix of sand, gravel, and small stones excavated directly from pits or riverbanks. Unlike crusher run, it is not mechanically crushed or screened, resulting in inconsistent sizing.

#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

Bank Run Gravel

• + Low cost
• + Minimal processing
• + Good general fill material

• − Inconsistent size
• − Poor compaction compared to crusher run
• − Can contain excess sand

#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.

Unscreened blend ranging from sand up to 2" stones. Color varies by region.
