1. What is Density of Water Bound Macadam (WBM)?

Definition: This calculator computes the density of Water Bound Macadam (road base material) based on its mass and volume.

Purpose: It helps civil engineers and construction professionals determine the density of WBM for road construction projects.

2. How Does the Calculator Work?

The calculator uses the density formula:

\[ \rho = \frac{m}{V} \]

Where:

\( \rho \) — Density (kg/m³)
\( m \) — Mass (kg)
\( V \) — Volume (m³)

Explanation: The mass of WBM is divided by its volume to calculate density.

3. Importance of WBM Density Calculation

Details: Proper density measurement ensures road base stability, load-bearing capacity, and compliance with construction specifications.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Typical WBM density ranges between 2000-2200 kg/m³.

5. Frequently Asked Questions (FAQ)
