1. What is MOT Type 1 Calculator?

Definition: This calculator estimates the volume of MOT Type 1 aggregate needed based on the length, width, and depth of the area to be covered.

Purpose: It helps construction professionals and DIYers determine how much MOT Type 1 is required for sub-base preparation in driveways, paths, and other construction projects.

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 (feet)
• 27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator converts all measurements to feet, calculates the cubic footage, then converts to cubic yards by dividing by 27.

3. Importance of MOT Type 1 Calculation

Details: Proper MOT Type 1 volume estimation ensures stable sub-base preparation, proper load-bearing capacity, and cost-effective material purchasing.

4. Using the Calculator

Tips: Enter the length and width in feet, and depth in inches. All values must be > 0. The depth is automatically converted to feet for calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is MOT Type 1?
A: MOT Type 1 is a granular sub-base material certified to the Ministry of Transport specification, used as a load-bearing layer beneath surfaces like driveways and patios.

Q2: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard, so dividing by 27 converts cubic feet to cubic yards.

Q3: What's the typical depth for MOT Type 1?
A: For domestic driveways, 4-6 inches is common. For heavier traffic, 6-8 inches may be required.

Q4: Does this include compaction allowance?
A: No, MOT Type 1 typically compacts by about 20-30%, so you may need to order extra material to account for this.

Q5: How do I convert cubic yards to tons?
A: MOT Type 1 weighs approximately 1.5 tons per cubic yard. Multiply your cubic yards by 1.5 to estimate weight.
