1. What is Class 2 Road Base?

Class 2 Road Base is a compactible aggregate material used as a base for roads, driveways, and other construction projects. It typically consists of crushed rock mixed with fines that help it compact well.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Length \) — Length in feet
• \( Width \) — Width in feet
• \( 0.167 \) — Conversion factor for 2 inches depth to cubic yards

Explanation: The formula calculates volume in cubic yards for a 2-inch depth by multiplying length × width × depth conversion factor.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you order the correct amount of material, avoiding costly overages or project delays from shortages.

4. Using the Calculator

Tips: Measure the length and width of your project area in feet. The calculator assumes a standard 2-inch depth for Class 2 Road Base applications.

5. Frequently Asked Questions (FAQ)

Q1: Why 0.167 as the multiplier?
A: This converts square feet at 2-inch depth to cubic yards (1 cubic yard = 27 cubic feet; 2 inches = 0.167 feet).

Q2: Can I use this for different depths?
A: For other depths, adjust the multiplier proportionally (e.g., 4 inches would use 0.333).

Q3: How much compaction should I expect?
A: Class 2 Road Base typically compacts about 20-30%, so you may need to account for this in your order.

Q4: Is this suitable for heavy vehicle traffic?
A: Yes, Class 2 Road Base is commonly used as a stable base for roads and parking areas.

Q5: How does this compare to Class 1 Road Base?
A: Class 2 has slightly larger aggregate size and different composition, making it more suitable for certain applications.
