1. What is a Road Camber Calculator?

Definition: This calculator estimates the camber height of a road based on road width, height difference, and half road width.

Purpose: It helps civil engineers and road construction professionals determine the appropriate camber for proper road drainage and vehicle safety.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Camber height (meters)
• \( W \) — Road width (meters)
• \( h \) — Height difference (meters)
• \( L \) — Half road width (meters)

Explanation: The formula calculates the appropriate camber height needed to ensure proper drainage from the road surface.

3. Importance of Road Camber Calculation

Details: Proper camber ensures water drainage from the road surface, prevents water accumulation, and improves vehicle safety by reducing hydroplaning risks.

4. Using the Calculator

Tips: Enter the total road width, height difference between edges and center, and half of the road width. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is road camber?
A: Road camber is the slope provided to the road surface in the transverse direction to drain off rainwater.

Q2: What's a typical camber height?
A: For paved roads, camber typically ranges between 2-4% of the road width, depending on rainfall intensity.

Q3: Why use half road width in the calculation?
A: The half width represents the distance from the center to the edge, which is crucial for calculating the slope.

Q4: How does height difference relate to camber?
A: Height difference is the vertical drop from the center to the edge that creates the drainage slope.

Q5: When would I need to calculate camber?
A: During road design, construction, or when evaluating existing roads for drainage performance.
