12. Cross sectional elements

Try these first

1. 1.

   What is the importance of friction in pavement design?

   Hint

   Think about vehicle control during driving.

2. 2.

   Define what camber is in the context of road design.

   Hint

   Consider the angle of the road surface.

3. 3.

   What is the typical coefficient of friction recommended for road safety?

   • 0.25
   • 0.35-0.4
   • 0.55

   Hint

   Recall the values mentioned for driving scenarios.

4. 4.

   True or False: Side slopes of embankment are irrelevant to road right of way planning.

   • True
   • False

   Hint

   Think about the factors affecting right of way mentioned.

5. 5.

   Design a road section incorporating ideal friction and camber for both dry and wet conditions based on traffic load. Discuss your approach and expected results.

   Hint

   Refer to the friction and camber values in the lesson.

6. 6.

   How would inadequate drainage affect the lifespan of a roadway structure? Analyze the implications based on design principles.

   Hint

   Reflect on how drainage design was discussed.
