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
- Length (ft): The total length of the area to be covered.
- Width (ft): The total width of the area to be covered.
- Depth (inches): The depth of the crush and run layer.
- 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:
Total Tons Required=12×27Length (ft)×Width (ft)×Depth (inches)×Density (tons/yd3)
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:
Total Cost=Total Tons Required×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: $30
- Density: 1.5 tons/yd³
Step 1: Calculate Total Tons Required
First, use the formula to find the total tons of crush and run needed:
Total Tons Required=12×27Length×Width×Depth×Density
Substitute the values:
Total Tons Required=12×2750×20×4×1.5
Simplify:
Total Tons Required=3244000×1.5
Total Tons Required≈18.52tons
Step 2: Calculate Total Cost
Now, calculate the total cost using the formula:
Total Cost=Total Tons Required×Cost per Ton
Substitute the values:
Total Cost=18.52×30
Simplify:
Total Cost≈555.60$
Final Results:
- Total Tons Required: 18.52 tons
- Total Cost: $555.60
Frequently Asked Questions
What is crush and run gravel?
Crush and run, also called crusher run, is a blend of crushed stone and stone dust. It compacts well and is commonly used for driveways, paths, and base layers.
How deep should crush and run be?
The required depth depends on the project type, soil conditions, drainage, expected traffic, and local installation requirements. Follow the recommendations for your specific driveway, patio, or base project.
Why does the calculator estimate tons from volume?
Suppliers usually sell crush and run by weight, while project measurements produce a volume. The calculator uses material density to convert volume into estimated tons.
Can the actual number of tons vary?
Yes. Moisture content, stone size, compaction, and supplier material density can affect the final delivered weight. Confirm the density and order quantity with your supplier.
Should I order extra crush and run?
Usually, yes. Add extra material for compaction, uneven ground, spillage, and minor adjustments during installation.
Does the total cost include delivery?
The result estimates material cost only, based on the price per ton entered. Delivery, taxes, spreading, and installation costs may be separate.
Can I use this calculator for other gravel types?
Yes, but different materials have different densities. Use the density or weight information for the specific gravel, stone, or aggregate you plan to order.
