1. What is a Concrete Ramp Slope Calculator?

Definition: This calculator computes the slope of a concrete ramp based on the rise and run measurements.

Purpose: It helps construction professionals and designers ensure ramps meet accessibility standards and functional requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Slope — Ratio of vertical to horizontal distance (unitless)
• Rise — Vertical height change (units)
• Run — Horizontal distance (units)

Explanation: The slope is calculated by dividing the vertical rise by the horizontal run.

3. Importance of Ramp Slope Calculation

Details: Proper slope calculation ensures ADA compliance, safety, and functionality of concrete ramps.

4. Using the Calculator

Tips: Enter the rise and run in consistent units (both in inches, feet, meters, etc.). Run must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the maximum slope for ADA compliant ramps?
A: ADA requires a maximum slope of 1:12 (8.33%) for wheelchair ramps.

Q2: How do I convert slope to percentage?
A: Multiply the slope ratio by 100. For example, 0.0833 × 100 = 8.33%.

Q3: What's a typical slope for vehicle ramps?
A: Vehicle ramps typically range from 10% to 20% slope depending on the application.

Q4: How do I measure rise and run in the field?
A: Measure vertical change (rise) with a level and tape measure, and horizontal distance (run) along the ramp surface.

Q5: Does this calculator account for ramp thickness?
A: No, this calculates the finished surface slope. Account for subgrade when constructing.
