Volume Formula:
| From: | To: |
Crushed rock fill is a construction material made from crushed stone of various sizes. It's commonly used as a base material for foundations, roads, driveways, and drainage systems due to its excellent compaction properties and stability.
The calculator uses the volume formula:
Where:
Explanation: This formula calculates the cubic volume of space that needs to be filled with crushed rock, helping determine the quantity of material required for a project.
Details: Accurate volume calculation is essential for estimating material requirements, project budgeting, and minimizing waste. Proper calculation ensures you purchase the right amount of crushed rock, avoiding both shortages and excess material.
Tips: Measure the length, width, and depth of the area in feet. Enter these values into the calculator. All values must be positive numbers. For irregularly shaped areas, break them down into regular shapes and calculate each separately.
Q1: How much extra material should I account for?
A: It's recommended to add 10-15% extra to account for compaction, settling, and measurement errors.
Q2: What's the typical depth for different applications?
A: Driveways typically require 4-6 inches, pathways 2-3 inches, and structural bases 6-12 inches, depending on the project requirements.
Q3: How do I convert cubic feet to tons?
A: Multiply the cubic footage by the material density (typically 1.25-1.35 tons per cubic yard, then convert cubic feet to cubic yards by dividing by 27).
Q4: Can I use this for irregularly shaped areas?
A: For irregular shapes, divide the area into regular rectangles, calculate each volume separately, then sum the results.
Q5: Does the rock size affect the calculation?
A: The volume calculation remains the same regardless of rock size, though larger rocks may require different compaction methods and may have slightly different coverage rates.
