1. What is the Crushed Limestone Calculator?

The Crushed Limestone Calculator helps determine the amount of crushed limestone needed for a project based on area, depth, and material density. It's essential for landscaping, construction, and road base projects.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Area \) — Project area in square feet
• \( Depth \) — Depth of limestone layer in feet
• \( Density \) — Material density in pounds per cubic foot (typically 95-105 lb/ft³ for crushed limestone)
• 2000 — Conversion factor (pounds to tons)

Explanation: The formula calculates volume in cubic feet, converts to weight using density, then converts pounds to tons.

3. Importance of Accurate Calculation

Details: Accurate calculation ensures you order the right amount of material, avoiding costly over-ordering or project delays from under-ordering.

4. Using the Calculator

Tips: Measure your project area accurately. For irregular areas, divide into rectangles. Typical depth for driveways is 4-6 inches (0.33-0.5 ft). Default density is 95 lb/ft³ (adjust if needed).

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density of crushed limestone?
A: Most crushed limestone has a density between 95-105 pounds per cubic foot.

Q2: How do I measure irregular areas?
A: Divide into rectangular sections, calculate each separately, then sum the totals.

Q3: How much should I add for compaction?
A: Add 10-20% to account for compaction, depending on the compaction method.

Q4: What depth should I use for different projects?
A: Driveways: 4-6", walkways: 2-3", base for pavers: 4-6".

Q5: How does moisture affect the calculation?
A: Wet limestone is denser. For very wet material, increase density by 5-10%.
