15.2.2. Maximum and minimum super-elevation

Try these first

1. 1.

   What is the maximum allowable super-elevation on plain terrain?

   Hint

   Think of the terrain types discussed in class.

2. 2.

   Why is minimum super-elevation important?

   Hint

   Consider the implications of water accumulation on roads.

3. 3.

   What is the maximum super-elevation for urban roads?

   • 2%
   • 4%
   • 6%

   Hint

   Think of the different terrain types we've discussed.

4. 4.

   True or False: The maximum super-elevation on plain terrain is 10%.

   • True
   • False

   Hint

   Recall the specific limits for different terrains.

5. 5.

   Design a new road segment in hilly terrain ensuring proper super-elevation for heavy and light vehicles, specifying the safety limits.

   Hint

   Refer to IRC safety guidelines for determining ratios.

6. 6.

   Calculate necessary super-elevation for two new curves, one in flat terrain and another in urban setting, and explain the implications for vehicles.

   Hint

   Think back to your notes on urban planning and traffic safety.
