19.1. Overview

Try these first

1. 1.

   What are the two main types of pavements?

   Hint

   Think of the materials used.

2. 2.

   What is the purpose of a pavement?

   Hint

   Consider the forces acting on it.

3. 3.

   What is the primary function of a highway pavement?

   • A. To beautify roads
   • B. To distribute loads
   • C. To lower noise

   Hint

   Consider the engineering purpose behind pavement construction.

4. 4.

   True or False: Rigid pavements can deform significantly under load.

   • True
   • False

   Hint

   Think about rigidity versus flexibility.

5. 5.

   Evaluate the impact of using low-quality materials in the top layers of a flexible pavement design.

   Hint

   Consider what happens when the surface cannot hold repeated traffic stress.

6. 6.

   Compare the expected lifespan of flexible pavements versus rigid pavements under high traffic conditions.

   Hint

   Think about how materials differ in stress handling.
