1. What is MOT Type 1?

Definition: MOT Type 1 is a granular sub-base material used as a foundation for roads, driveways, patios, and other construction projects.

Purpose: It provides a stable, load-bearing layer that helps with drainage and prevents settlement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of MOT Type 1 (cubic yards)
• \( L \) — Length (feet)
• \( W \) — Width (feet)
• \( D \) — Depth (inches, converted to feet in calculation)
• 27 — Cubic feet per cubic yard (conversion factor)

Explanation: The calculator converts all measurements to feet, calculates cubic feet, then converts to cubic yards.

3. Importance of Accurate MOT Type 1 Calculation

Details: Proper 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 carefully in feet, and specify depth in inches (typically 4-6 inches for driveways). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical depth for MOT Type 1?
A: For driveways, 4-6 inches is common. For heavy traffic areas, 6-8 inches may be needed.

Q2: How do I convert cubic yards to tons?
A: MOT Type 1 weighs about 1.5 tons per cubic yard. Multiply volume by 1.5 to estimate weight.

Q3: Should I allow for compaction?
A: Yes, MOT Type 1 compacts about 20-30%. Consider adding 10-15% to your calculated volume.

Q4: Can I use this for irregular shapes?
A: For irregular areas, divide into rectangular sections and calculate each separately.

Q5: What's the coverage per ton?
A: At 4" depth, one ton covers about 80-100 square feet. At 6" depth, about 50-60 square feet.
