Yes, #57 gravel is classified as 3/4-inch crushed stone.
Yes, #57 stone and 3/4-inch stone are generally the same product. While "3/4-inch stone" is a common descriptive name used by homeowners and landscapers, "#57" is the official technical classification used by the AASHTO (American Association of State Highway and Transportation Officials) and ASTM to define its specific size and grading.
When ordering gravel, 34three-fourths34-inch gravel is most commonly referred to as #57 stone. It is the industry standard for driveways, drainage solutions (like French drains), and concrete mixes.
3/4-inch gravel is a highly versatile aggregate used for structural bases, driveways, drainage systems (like French drains), and concrete mixing. Depending on your project, it comes in two main varieties: Clean (no dust/sand) or Minus/Crushed (mixed with rock dust).
#57 gravel typically ranges from 12one-half𝟏𝟐 inch to 𝟏𝟏𝟐 inches in diameter. The most common average size is about 34three-fourths𝟑𝟒 of an inch, or roughly the size of a nickel or quarter.
#57 stone is a versatile, uniformly sized crushed aggregate (typically 12one-half12 to 112 inches in diameter) that is highly prized for its exceptional drainage properties and ability to bear heavy loads without compacting into a solid mass.
A layer of #57 gravel (which is typically 0.50.50.5 to 0.750.750.75 inches in crushed angular stone) should generally be 4 to 8 inches thick, depending entirely on your specific project.
A cubic yard of 3/4" gravel typically weighs between 2,400 and 3,000 lbs (1.2 to 1.5 tons), with a standard industry average of about 2,800 lbs per cubic yard.
Putting salt on a gravel driveway is generally advised against because it attracts moisture and breaks down the underlying soil. Instead of melting the snow and ice to leave a clean surface, the salt mixes with the melting ice and gravel to create a muddy, soft, and uneven mess.
3/4" crushed stone is most commonly gray, blue-gray, or salt-and-pepper in color. However, the exact color depends entirely on the type of parent rock native to your local quarry.
If you are talking clear stone you won't get any real compaction, as there are no fines in it, you might drive some of it into the sub grade but it won't compact. The reason we ( water and sewer and roadwork) use 3/4 clear stone is when we can't safely do compaction because of high water table.
For a comfortable, stable walking surface, the best gravel size is between 14one-fourth𝟏𝟒 and 38three-eighths𝟑𝟖 inches in diameter. This size is large enough to provide good drainage but small enough to pack well, preventing the stones from shifting too much under your feet.
AASHTO #57 (coarse aggregate stone has 100% passing 1-1/2" screen, 95-100% passing 1" screen) is an open-graded, self-compacting aggregate blend of size 5, 6, & 7 stone. This material cannot be 'compacted' in a true sense, but can be properly oriented with compaction equipment.
#57 rock (or #57 stone) is a mid-sized, crushed aggregate. It is angular and jagged rather than smooth.
57 stone is a washed, angular crushed stone aggregate typically sized between 12one-half12 inch and 111 inch. It is primarily used for concrete mixes, driveways, drainage systems, and paver bases.
To permanently kill weeds on gravel, apply total vegetation control herbicides that kill existing weeds and sterilize the soil against regrowth. Alternatively, permanently salt the soil or lay heavy-duty landscape fabric under the gravel to block sunlight.
As others have said- never salt gravel. It WILL melt the ice, but the brine will sink into the gravel and actually loosen the hard packed gravel base. Then you road will become spongy soft:-(. Sand is a good alternative.
How to Maintain a Gravel Driveway for Long-Lasting Durability
3/4-inch gravel is the industry standard for driveways, paver patios, and drainage. Depending on whether you get "crushed" (includes stone dust to lock together) or "washed" (clean stones for water flow), it is perfect for structural support, sub-bases, landscaping, and French drains.
A full dump truck load of gravel typically costs between $500 and $1,500+, depending on the size of the truck and the type of gravel. The total price is determined by the material cost per ton (or cubic yard) combined with the delivery distance from the quarry.
Gravel that hardens like concrete is generally a mix of crushed stone, coarse sand, and fine rock dust (often called "fines"). When wetted, compacted, and dried, the dust acts as a natural binder.
#57 gravel (also known as #57 stone) is a highly versatile, crushed aggregate ranging from 12one-half12 to 112 inches in size. Because it is washed and contains no "fines" (stone dust or sand), it allows water to pass through freely, making it the industry standard for drainage systems, driveway top layers, and structural bases.
Coca-Cola acts as a powerful surface retarder on freshly poured concrete because of its high sugar content. By slowing down the curing process on the top layer, it allows workers to easily wash away the cement paste with a hose or pressure washer, leaving behind a textured, decorative "exposed aggregate" finish.
Crushed stone #57 refers to stone that is about ¾”. This is typically used for concrete mix, landscaping and drainage.
