2.7.3. Importance in Pavement Engineering

Try these first

1. 1.

   What is compressibility in terms of soil?

   Hint

   Think about what happens to sponges when you squeeze them.

2. 2.

   Is clay considered a compressible soil?

   Hint

   Consider the texture differences between clay and sand.

3. 3.

   What does compressibility refer to in soils?

   • Ability to maintain shape
   • Reduction in volume under pressure
   • Resistance to water flow

   Hint

   Think about what happens when you apply weight.

4. 4.

   True or False: High compressibility is beneficial for subgrade performance.

   • True
   • False

   Hint

   Consider the effects of settlement on road integrity.

5. 5.

   Given a project requiring construction over a peat layer, outline an engineering approach to address its high compressibility.

   Hint

   Consider effective strategies for improving soil strength.

6. 6.

   Evaluate the long-term consequences of not stabilizing a highly compressible clay before pavement construction.

   Hint

   Think about the potential for change over time without intervention.
