Crush and Run Calculator

Formula

The formula to calculate the amount of Crush and Run needed (CR) is:

\[ CR = \frac{A \times D \times W}{2000} \]

Where:

\( CR \) is the amount of Crush and Run needed in tons.
\( A \) is the area in square feet.
\( D \) is the depth in inches.
\( W \) is the weight of Crush and Run per cubic foot, typically around 100 lbs.

What is Crush and Run?

Crush and Run, also known as crusher run, is a type of gravel that is commonly used in places where motor vehicles are often driven or parked. It is a mix of stone powder and small crushed stone, retaining the strength of the top layer of a driveway. It is durable, long-lasting, and versatile, making it suitable for various surfaces and landscaping projects. The stones and dust are able to compact and create a hard surface that is water-resistant and adds stability to the driveway or path where it is used.

Example Calculation

Consider an example where:

Area (A): 500 square feet
Depth (D): 4 inches
Weight per cubic foot (W): 100 lbs

Using the formula to calculate the amount of Crush and Run needed:

\[ CR = \frac{500 \times 4 \times 100}{2000} = 100 \text{ tons} \]

This means that the amount of Crush and Run needed for this example is 100 tons.
