You probably already know that the size and type of stone you need for your project depends on how you intend to use the stone. #57 stone is crushed stone aggregate used in a variety of construction and landscaping projects. In short, #57 stone is a gravel-like material consisting of specifically sized stones. You may not know that gravel and crushed stone are different materials. Gravel is usually less angular because it naturally occurs by erosion. Crushed stone comes from natural rock deposits and is angular and jagged in shape.
Crushed stone is made from a suitable rock formation during the mining process. A crusher breaks down the rock into various sizes. Crushed stone varies in size. The number “57” is a number that refers to the size sieve that was used to screen and sort the stone. It means that the stone was put through the #57 sieve which produces gravel stones of about 1” to 1.5” in size. #1 crushed stone refers to the largest sized crushed stone. It is about 2″ to 4″ in size. Its uses are for tor larger jobs such as culvert ballast. At the other end of the size chart is a very small sized stone– #411 stone. It consists of a mixture of stone dust and #57 stone. It is used when the project calls for a stone dust that mixes with the larger stone and settles well.
When you order #57 stone, you are ordering a gravel-like material with individual stones about the same size as nickels and quarters. The stone material itself may consist of granite, limestone, washed gravel,, argillite or quartzite. You can also find #57 crushed concrete. If you are looking for a specific type of stone, you will want to specify your preference as to the type of rock you want when you order it.
To help you estimate the amount of #57 crushed stone your project may require, you can use the following measurements:
Density: 1 ton = 0.83 cu yd. or 1 cu yd. = 1.2 ton
Coverage: 2 inch layer = 100 sq. ft., needs about 0.62 cu yd.
Coverage: 5 inch layer = 100 sq. ft., needs about 1.54 cu yd.
Common Uses for #57 Stone
#57 stone is one of the most commonly used types of crushed stone due to its versatility. It is ideal for a variety of projects. It is used as aggregate in concrete. It works well as a base for building sidewalks, asphalt roads, driveways, and railroad ballast. In asphalt paving, the tar and other aggregates are able to sink into the spaces between the stones, creating a firm, solid base for it.
If you want to leave a road or driveway unpaved, #57 stone is very suitable for that purpose. The angular, irregular shape of this stone allows it to mesh together on a flat surface and hold its shape well, providing a relatively stable unpaved surface.
Another way this stone is frequently used is to provide drainage. Water percolates through the stones and channels water away from wet areas. It is the first choice for use in French drains, septic drainage fields and other types of drainage projects. You will also note that it is the preferred gravel for managing drainage around retaining walls, lining underground pipes, sewers and utility lines/cables.
Considerations and Benefits Associated with Using #57 Stone
The most important consideration is the size and type of stone you need for the project. The stone size is what determines the best application for it. Your project may call for a couple of different types and sizes of stone, but #57 stone provides three important benefits.
- Affordable for Any Budget
#57 stone is extremely common. That means you will be able to find it easily and buy it at the lowest and most affordable prices.
- Versatile Uses
The versatility of #57 crushed stone makes it one of the most widely used types of stone in the construction and agriculture industries. You can use it for so many different purposes.
- Drainage Management
#57 stone is the ideal size and weight for correcting and controlling drainage just about anywhere on your property. It allows water to drain naturally and prevent flooding and pooling.
With all of those benefits, why would anyone use anything other than #57 stone? As noted earlier, the size and shape of the stone determines its most appropriate use. Like any other stone, #57 crushed stone is not suitable for use in every project. Here are some factors you need to consider before you order stone for your project.
- Gradient of the Surface
#57 stone may not be the appropriate stone for use on the side of a hill or a sloped surface. The weight and shape of the stone makes it prone to sliding and washing in heavy storms. Talk to your dirt supplier about the best kind of material to use on a sloped surface.
- Muddy or Dirty Location
#57 stone works for improved drainage, but it will be overwhelmed if simply placed on top of a dirt or mud surface. If you want to use the stone to improve drainage, you will need to do some site prep involving excavation to make the project successful. Your dirt supplier or landscape architect can advise you on what to do and whether you need to consider different stone or stone in addition to #57.
- Degree of Compaction
By itself #57 stone will not, create a highly compacted surface. You will need to use other material or add material to the stone to achieve a firm surface. Your dirt supplier or project engineer can advise you on the material you need to use to achieve your desired result.
