What Size Gravel for Driveway?

A well-built gravel driveway uses three layers of progressively smaller stone: Base Layer (4 inches) Use #3 stone (1-2 inches) or #4 stone (1.5-3 inches). These large angular stones create a stable foundation and won't sink into soft soil. A geotextile fabric under this layer prevents the stone from migrating into the subgrade. Middle Layer (4 inches) #57 stone (3/4 to 1 inch) is the standard choice. It fills the gaps in the base layer, adds stability, and provides a transition to the finer top layer. Top Layer (2-3 inches) #8 gravel (3/8 to 1/2 inch) or crushed limestone creates a smooth driving surface. Some homeowners prefer #411 (a blend of #57 stone and stone dust) because the dust fills voids and compacts into a very firm surface. What to Avoid Avoid using pea gravel or river rock for driveways — their rounded shape means they never lock together and will constantly shift under tires, creating ruts.

Is Bank Run Gravel Good for a Driveway?

Good Underneath, Not on Top Bank run makes an excellent driveway base. The wide gradation means small particles wedge between the large ones under compaction, so the layer locks up and spreads load well. It costs roughly a third of what processed stone costs, which is why rural driveways and farm lanes are built on it. What it will not do is finish. Raw bank run has no wearing course, it tracks onto your shoes and tires, and it ruts under traffic. Cap it with 2 to 3 inches of crusher run or #57 once the base is compacted and crowned. How to Build It Spread in lifts and compact each one rather than dumping the full depth at once. On soft clay, lay geotextile fabric first so the stone does not punch down into the mud. Crown the surface slightly so water runs off instead of ponding.

What Is the Difference Between Bank Run and Crusher Run?

One Is Processed, One Is Not Crusher run is crushed to a controlled top size with the stone dust deliberately retained so the material binds. It packs into a hard surface that sheds rain, which is why it is the standard driveway wearing course. Bank run is dug out of a gravel bank or pit and sold essentially as-is. Nothing is crushed, nothing is washed, and nothing is graded to a spec. The blend is whatever the deposit holds, so it is looser, more variable, and considerably cheaper. Which to Buy Use crusher run for the surface. Use bank run underneath it, or anywhere bulk fill matters more than finish. On a driveway you often want both: bank run for the base, crusher run for the top 2 to 3 inches.

Does Bank Run Gravel Drain Well?

Partly, and Not Enough for a Drain Water does move through the coarse fraction of bank run, but the material commonly carries 10 percent or more sand and fines, and those fines slow flow considerably. Bank run drains far better than clay and far worse than clean stone. Never in a French Drain The fines will choke the trench, which is the exact failure a drain exists to prevent. Use clean, washed stone with no fines: #57 or #4. The same applies behind retaining walls and around foundation drains. There is a second reason to keep it out of wet locations. Where fines trap water in the section, a bank run layer can heave in freeze-thaw. Daylight the edge of the base wherever the site allows so water has somewhere to go.

Why Do Bank Run Gravel Prices Vary So Much?

Freight, Not Material Bank run has the widest gap between gate price and delivered price of any common aggregate. Published 2026 list prices put it near $8.50 per ton FOB at the quarry, while delivered pricing commonly runs $15 to $30 per ton. Consumer guides quoting $25 to $40 are usually reporting delivered prices in markets with a long haul. On a material this cheap, trucking is most of the bill. Delivery typically adds $50 to $150 per load within a normal radius, with per-mile charges beyond it. What That Means for You The pit's price per ton barely matters if you are far from it. Compare delivered quotes to your address, not gate prices. And confirm which product you are being quoted, since crushed bank run is a separate, higher-priced line item from plain bank run.

#57 Gravel vs Bank Run Gravel: Size, Cost, and Which to Use

#57 Gravel runs about $39 per ton and Bank Run Gravel about $7 per ton. Compare size, drainage, compaction, and which one to use.

Overview

#57 Gravel

The 57 comes from the ASTM C33 grading table, and the same size appears in AASHTO M43. 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 pit-run aggregate dug straight from a gravel bank, pit, or river terrace and sold with almost no processing. It costs $7 to $16 per ton in 2026, weighs 1.4 to 1.65 tons per cubic yard, and is the cheapest truckload of anything most yards will sell you. What you get is whatever the deposit holds: sand, small gravel, stones up to several inches, and enough silt or clay fines to fill the gaps.

Common Uses

Pros & Cons

#57 Gravel

+ Sold at nearly every quarry for $39 to $65 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

+ Cheapest bulk aggregate at $7 to $16 per ton
+ Wide gradation compacts and locks up well
+ Widely available anywhere there is a pit
+ Good structural fill under a wearing course

− Gradation and fines vary load to load
− Fines slow drainage, so it is wrong for drains
− Needs a capping layer for any traffic
− Can hold water and heave where it cannot drain

Cost Comparison

Measure	#57 Gravel	Bank Run Gravel
Per ton	$39 – $65	$7 – $16
Per cubic yard	$42 – $122	$20 – $40

Sizes & Colors

#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.

Bank Run Gravel

An unscreened blend running from sand and fines up through stones of 4 to 6 inches, with most of the material between 1/4 inch and 3 inches. There is no standard mix. The deposit sets the blend, so the pile at one pit looks nothing like the pile at the next one, and color follows the local geology from gray to brown to reddish tan.
