Type 1 Calculator Paving Expert

Type 1 Volume Formula:

\[ V = \frac{L \times W \times D}{27} \]

Volume (cu yd):

1. What is a Type 1 Calculator?

Definition: This calculator estimates the volume of Type 1 aggregate needed based on length, width, and depth measurements.

Purpose: It helps construction professionals and DIYers determine how much Type 1 material is required for sub-base preparation in paving projects.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{L \times W \times D}{27} \]

Where:

\( V \) — Volume of Type 1 (cubic yards)
\( L \) — Length (feet)
\( W \) — Width (feet)
\( D \) — Depth (feet)
27 — Cubic feet per cubic yard

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

3. Importance of Type 1 Volume Calculation

Details: Proper Type 1 volume estimation ensures stable sub-base for paving, proper load distribution, 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.

5. Frequently Asked Questions (FAQ)

Q1: What is Type 1 aggregate?
A: Type 1 is a graded aggregate from 40mm down to dust, used as a sub-base material for roads, patios, and driveways.

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

Q3: How do I convert depth from inches to feet?
A: The calculator automatically converts inches to feet by dividing by 12.

Q4: Does this include compaction factor?
A: No, consider adding 10-20% to the calculated volume for compaction depending on material and application.

Q5: How much does Type 1 weigh per cubic yard?
A: Typically about 1.4-1.6 tons per cubic yard, depending on moisture content and compaction.
