Try these first

1. 1.

   Define an exceptional gradient in your own words.

   Hint

   Think about the context in which you would design such a road.

2. 2.

   What is the maximum length an exceptional gradient can be?

   Hint

   Relate this to the safety measures required.

3. 3.

   What is the maximum permissible length for an exceptional gradient?

   • 50 meters
   • 100 meters
   • 150 meters

   Hint

   Think about how steep gradients can affect vehicles.

4. 4.

   True or False: Exceptional gradients can be used in flat terrain.

   • True
   • False

   Hint

   Consider the characteristics of flat roads.

5. 5.

   You are tasked to design a road in a mountainous area with specific terrain conditions. Describe the exceptional gradient you would choose and justify your decision.

   Hint

   Think about the interaction between gradient steepness and vehicle capabilities.
