1. What is a Road Camber Calculator?

Definition: This calculator determines the camber height (cross slope) of a road based on road width, height difference, and half road width.

Purpose: It helps road construction professionals in Ontario design proper road drainage and surface slope for safety and water runoff.

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 cross slope needed for proper road drainage and surface water runoff.

3. Importance of Road Camber Calculation

Details: Proper camber ensures water drainage, prevents water pooling, improves vehicle safety, and extends road lifespan.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a typical camber height for Ontario roads?
A: Most Ontario roads have a camber of 2-3% (2-3 cm per meter) for proper drainage.

Q2: Why is half road width used in the calculation?
A: Half width represents the distance from the centerline to the edge where the slope is measured.

Q3: How does camber affect driving?
A: Proper camber improves vehicle stability and prevents hydroplaning by ensuring quick water runoff.

Q4: When would I need to adjust the camber?
A: Adjustments may be needed based on rainfall intensity, road speed, and surface material.

Q5: Does this calculator account for Ontario's climate?
A: While it provides basic calculations, Ontario's freeze-thaw cycles may require additional considerations in actual design.
