17.2.3.2. Limiting gradient

Try these first

1. 1.

   What is a limiting gradient?

   Hint

   Think about what might happen if a gradient is too steep.

2. 2.

   Why are minimum gradients important?

   Hint

   Consider water drainage requirements.

3. 3.

   What is the function of a limiting gradient?

   • To enhance vehicle speed
   • To minimize costs while ensuring safety
   • To smoothen curves

   Hint

   Consider why we might not want steep roads.

4. 4.

   True or False: Exceptional gradients can be applied indefinitely in road design.

   • True
   • False

   Hint

   Think about the safety regulations in place.

5. 5.

   Design a road where you need to implement a limiting gradient of 6% for 100m surrounded by 5% stretches. Describe the challenges.

   Hint

   Consider traffic flow and construction costs as influencing factors.

6. 6.

   You are tasked with creating a report on the pros and cons of implementing exceptional gradients in mountainous regions. Present both sides.

   Hint

   Reflect on both the operational and safety outcomes.
