What are the different types of gravel? (with photos)

Most gravel is no more than 7 centimeters in diameter.

Gravel is classified as small rocks that generally do not exceed a certain size. Most types of gravel pieces do not exceed 2.5 or 3 inches (64 or 75 millimeters) in diameter. Gravel is often used in road construction and landscaping projects. Most are formed naturally, usually by the movement of bodies of water, but some, such as crushed stone, are man-made. Other types include bank gravel, bank, river, fine and gravel.

Shore gravel, or bank gravel as it is sometimes called, is often mixed with sand or some type of clay. Individual pieces often vary in size, with some pieces being quite small and others being quite large. This type is usually found in nature.

There are several types of gravel that can be found in or around moving bodies of water, such as streams or rivers. Bench gravel is an example and is usually deposited when the water level was higher than it normally is.

Crushed gravel is often used to fill in driveways and drainage areas.

Often the small, smooth stones and rocks at or around the bottom of streams and rivers are collected for use in construction and landscaping. Over time, the moving water washes the stones along the bottom, chipping away any jagged edges and smoothing the stone. This gravel is often added to a cementing agent as a concrete aggregate or used for landscaping materials. River-run gravel and creek rock are both types of gravel with edges naturally smoothed by a moving body of water. Pea gravel is another example, with the individual pieces usually being very small.

Gravel can be used in different landscaping projects.

Fine gravel can be found naturally or made, and is usually no more than 0.16 inches (4 millimeters) in diameter. This gravel is sometimes painted and is a popular addition to many aquariums. In road works, it can also be used in areas without heavy traffic, such as access roads or private roads.

Gravel is another type of naturally formed gravel and is sometimes called gravel. The name is revealing because it usually contains some amount of precious metals such as gold or silver. It is usually found in mines or in the extraction of gold.

Gravel is often used as an aggregate in concrete.

Man-made gravel, like crushed rock and crushed stone, can come in various sizes. When making these types of gravel, the natural stone is mechanically broken and sieved into mesh screens of different sizes. Limestone is often used for crushed crushed stone, but other types of stone are also used, including granite and dolomite.
