1. What is a 3/4 Crush Calculator?

Definition: This calculator estimates the volume of 3/4" crushed stone needed based on length, width, and depth measurements.

Purpose: It helps construction professionals and DIYers determine how much crushed stone is required for projects like driveways, walkways, and drainage systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of 3/4 crush (cubic yards)
• \( L \) — Length (feet)
• \( W \) — Width (feet)
• \( D \) — Depth (feet)
• 27 — Cubic feet per cubic yard (conversion factor)

Explanation: The length, width and depth are multiplied to get cubic feet, then divided by 27 to convert to cubic yards.

3. Importance of 3/4 Crush Calculation

Details: Proper volume estimation ensures proper project execution, prevents material shortages or excess, and helps with accurate cost estimation.

4. Using the Calculator

Tips: Enter the length, width, and depth in feet. All values must be > 0. For irregular areas, divide into rectangular sections and calculate separately.

5. Frequently Asked Questions (FAQ)

Q1: What is 3/4" crushed stone used for?
A: It's commonly used for base material under concrete slabs, driveways, drainage systems, and as a decorative ground cover.

Q2: How much does 3/4" crushed stone weigh?
A: Typically about 1.25-1.35 tons per cubic yard, depending on material and moisture content.

Q3: What depth should I use for a driveway?
A: Typically 4-6 inches for residential driveways, but consult local recommendations.

Q4: Should I account for compaction?
A: Yes, consider adding 10-20% more material to account for compaction, especially for base layers.

Q5: How do I convert cubic yards to tons?
A: Multiply cubic yards by 1.25 (average weight per cubic yard) to get approximate tons needed.
