1. What is Crusher Run?

Crusher run is a type of gravel that consists of angular crushed rock, stone dust, and small gravel particles. It's commonly used as a base material for driveways, roads, and other construction projects due to its excellent compaction properties.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Volume \) — Volume in cubic yards (yd³)
• 1.4 — Conversion factor from cubic yards to tons

Explanation: This formula converts volume measurements in cubic yards to weight measurements in tons using the standard conversion factor for crusher run material.

3. Importance of Accurate Calculation

Details: Accurate calculation of crusher run material is crucial for proper project planning, budgeting, and ensuring you have the right amount of material for your construction project without over-ordering or running short.

4. Using the Calculator

Tips: Enter the volume in cubic yards (yd³). Make sure to measure your area accurately and calculate the volume properly before using this calculator.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 1.4?
A: The factor 1.4 represents the approximate weight in tons of one cubic yard of crusher run material, accounting for its density and compaction characteristics.

Q2: How do I calculate volume for my project?
A: Measure the length, width, and depth of the area in feet, then calculate cubic feet and convert to cubic yards (divide by 27).

Q3: Does the density vary between different types of crusher run?
A: Yes, density can vary slightly depending on the specific composition and source of the material, but 1.4 is a standard average conversion factor.

Q4: Should I order extra material?
A: It's generally recommended to order 5-10% extra material to account for compaction, spillage, and measurement variations.

Q5: Can this calculator be used for other materials?
A: No, this calculator is specifically designed for crusher run. Different materials have different density conversion factors.
