Crusher Run Formula:
| From: | To: |
Crusher run is a type of gravel that consists of angular crushed rock, ranging in size from 3/4-inch down to fines. It's commonly used as a base material for driveways, walkways, and other construction projects due to its excellent compaction properties.
The calculator uses the formula:
Where:
Explanation: The formula calculates the volume in cubic yards and multiplies by the density to determine the weight in tons.
Details: Accurate calculation of crusher run is essential for proper project planning, budgeting, and ensuring you order the correct amount of material to complete your project efficiently.
Tips: Enter all dimensions in meters. Measure the area accurately and consider adding 5-10% extra material to account for compaction and spillage during installation.
Q1: What is the typical density of crusher run?
A: Crusher run typically has a density of about 1.6 tons per cubic yard, though this can vary slightly depending on the specific composition and moisture content.
Q2: How much does crusher run compact?
A: Crusher run typically compacts about 20-30% when properly installed and compacted with mechanical equipment.
Q3: Can I use this calculator for other gravel types?
A: This calculator is specifically designed for crusher run. Other materials may have different densities and would require adjustment of the density factor.
Q4: How thick should a crusher run base be?
A: For most applications, a 4-6 inch compacted depth is recommended for driveways, while walkways may require 2-4 inches.
Q5: Does moisture affect the calculation?
A: Wet material will be heavier, but the 1.6 factor accounts for average moisture content. For very wet or very dry conditions, you may need to adjust slightly.
