1. What is Elevation Difference in Parabolic Camber?

Definition: The elevation difference calculation determines the vertical displacement at the edges of a parabolic camber in road construction.

Purpose: It helps engineers design proper road camber for effective drainage and vehicle safety.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( h_{Elevation} \) — Elevation difference (meters)
• \( X \) — Distance from center of camber (meters)
• \( H_c \) — Height of camber (meters)
• \( B \) — Pavement width (meters)

Explanation: The formula calculates the vertical displacement based on the parabolic shape of the road camber.

3. Importance of Elevation Calculation

Details: Proper elevation calculation ensures adequate road drainage, prevents water accumulation, and maintains vehicle stability.

4. Using the Calculator

Tips: Enter the distance from center, camber height, pavement width, and tolerance percentage (default ±5%). All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical tolerance for road camber?
A: Standard tolerance is ±5%, but this may vary based on project specifications.

Q2: How does pavement width affect the elevation difference?
A: Wider pavements require greater elevation differences to maintain the same camber slope.

Q3: What's a typical height for road camber?
A: Camber height typically ranges from 0.1m to 0.3m depending on road type and expected rainfall.

Q4: Why use a parabolic shape instead of straight camber?
A: Parabolic shape provides smoother transition and better drainage characteristics.

Q5: How does this relate to road gradient?
A: The elevation difference determines the cross slope or gradient from center to edge of the road.
