19.4. Flexible pavements

Try these first

1. 1.

   What is the primary purpose of a flexible pavement?

   Hint

   Think about what happens when a car drives on a road.

2. 2.

   Name the two main layers of a flexible pavement.

   Hint

   Think about the layers stacked on top of each other.

3. 3.

   What layer of flexible pavement directly contacts the traffic loads?

   • Binder Course
   • Surface Course
   • Sub-base Course

   Hint

   Think about which part of the pavement experiences the most wear and tear.

4. 4.

   True or False: The binder course requires higher quality materials than the surface course.

   • True
   • False

   Hint

   Consider which layer is under less stress.

5. 5.

   A highway experiences heavy traffic loads over time, resulting in rutting and fatigue cracking. Analyze how these issues arise and suggest design improvements.

   Hint

   Focus on how the load distribution plays a role in material selection.

6. 6.

   Compare the construction and material specifications of flexible pavements versus rigid pavements.

   Hint

   Consider how each type manages stress and impact.
