## Gravel Calculator

A gravel calculator is a tool that is used to determine the amount of gravel needed for a specific area or project. The calculator can be used for a variety of different types of gravel, including pea gravel, crushed stone, and more. In this article, we will discuss the different types of gravel, how to use a gravel calculator, and some tips for getting the most accurate results.

#### Gravel calculator formula

To calculate the amount of gravel needed for a project, you can use the following formula:

Gravel volume = length x width x depth x density

Where:

• length and width are the measurements of the area in feet
• depth is the desired depth of the gravel in inches
• density is the weight of the gravel per cubic foot (usually around 100-130 lbs)

For example, if you want to cover an area of 100 sq ft with 3 inches of gravel, and the gravel has a density of 115 lbs per cubic foot, the calculation would be:

Gravel volume = 100 x 3 x 115 = 34500 lbs or 17.25 tons

Keep in mind that this is a rough estimate and actual needs may vary based on the type of project and specific conditions on the ground.

#### Types of Gravel

Gravel is a loose aggregate that is made up of small rock fragments. There are many different types of gravel available, each with its own set of characteristics. The most common types of gravel include:

• Pea gravel: This type of gravel is made up of small, round stones that are typically about the size of a pea. Pea gravel is often used for landscaping projects, such as walkways and gardens.
• Crushed stone: Crushed stone is a type of gravel that is made up of larger rocks that have been crushed into smaller pieces. Crushed stone is typically used for construction projects, such as roads and building foundations.
• River rock: River rock is a type of gravel that is made up of smooth, rounded stones that have been worn down by the water. River rock is often used for landscaping projects, such as water features and rock gardens.
• Decomposed granite: Decomposed granite is a type of gravel that is made up of small pieces of granite that have been weathered and broken down over time. Decomposed granite is often used for pathways and outdoor living areas.
• Limestone: Limestone is a type of gravel that is made up of small pieces of limestone. Limestone is often used as a base layer for roads and other construction projects.
• Washed gravel: This type of gravel is made from crushed rock that has been cleaned to remove dirt and debris. It can be used for construction projects, such as driveways and roads, and also for landscaping projects.
• Bank gravel:also known as "natural gravel," naturally occurs in river beds or along stream banks. It is usually made up of a variety of rock types, such as granite, limestone, sandstone, and basalt. Bank gravel is typically rounded and smooth, as the action of water has worn it down over time. It comes in different sizes, ranging from small pebbles to large cobbles. Because of its natural origins, it can vary in color depending on the area it was sourced from, and it can be found in a wide range of shades such as white, black, grey, brown, and red.
