If you're planning a construction or landscaping project requiring crush and run gravel, it's important to calculate how much material you'll need and the overall cost. The Crush and Run Calculator simplifies this process by estimating the total tons of gravel required and the cost, saving you time and ensuring you order the correct amount.

What is Crush and Run Gravel?

Crush and run gravel, also known as crusher run, is a mix of gravel and stone dust. It is commonly used for driveways, pathways, and as a base material for construction because of its durability and compacting properties.

Inputs Required for the Crush and Run Calculator

1. Length (ft): The total length of the area to be covered.
2. Width (ft): The total width of the area to be covered.
3. Depth (inches): The depth of the crush and run layer.
4. Cost per Ton ($): Price of crush and run gravel per ton.

Formulas to Calculate Crush and Run Requirements

1. Total Tons Required

To calculate the total tons of crush and run gravel needed, use the following formula:

$\text{Total Tons Required} = \frac{\text{Length (ft)} \times \text{Width (ft)} \times \text{Depth (inches)}}{12 \times 27} \times \text{Density (tons/yd}^3\text{)}$

Where:

• Length (ft): Total length of the area.
• Width (ft): Total width of the area.
• Depth (inches): Depth of the material in inches.
• 12: Converts depth from inches to feet.
• 27: Converts cubic feet to cubic yards.
• Density: Standard density of crush and run gravel is approximately 1.5 tons per cubic yard.

2. Total Cost

To calculate the total cost, use the following formula:

$\text{Total Cost} = \text{Total Tons Required} \times \text{Cost per Ton}$

Where:

• Total Tons Required: From the previous calculation.
• Cost per Ton: The price of one ton of crush and run gravel.

Example Calculation

Let’s say you are covering a driveway with the following details:

• Length: 50 feet
• Width: 20 feet
• Depth: 4 inches
• Cost per Ton: $30
• Density: 1.5 tons/yd³

Step 1: Calculate Total Tons Required

First, use the formula to find the total tons of crush and run needed:

$\text{Total Tons Required} = \frac{\text{Length} \times \text{Width} \times \text{Depth}}{12 \times 27} \times \text{Density}$

Substitute the values:

$\text{Total Tons Required} = \frac{50 \times 20 \times 4}{12 \times 27} \times 1.5$

Simplify:

$\text{Total Tons Required} = \frac{4000}{324} \times 1.5$

$\text{Total Tons Required} \approx 18.52 \, \text{tons}$

Step 2: Calculate Total Cost

Now, calculate the total cost using the formula:

$\text{Total Cost} = \text{Total Tons Required} \times \text{Cost per Ton}$

Substitute the values:

$\text{Total Cost} = 18.52 \times 30$

Simplify:

$\text{Total Cost} \approx 555.60 \, \text{\$}$

Final Results:

• Total Tons Required: 18.52 tons
• Total Cost: $555.60
