Try these first

1. 1.

   What does CBR stand for?

   Hint

   It's commonly used in pavement engineering.

2. 2.

   Name one method to evaluate soil strength.

   Hint

   Think of common tests used in civil engineering.

3. 3.

   What is the primary purpose of evaluating soil strength in pavement engineering?

   • To enhance aesthetic appeal
   • To ensure proper load-bearing capacity
   • To minimize construction time

   Hint

   Think about the role of soil in supporting pavements.

4. 4.

   True or False: A weak subgrade soil can lead to significant pavement failure.

   • True
   • False

   Hint

   Consider how soil quality influences durability.

5. 5.

   You are designing a new road in an area with varying soil types. What factors will you consider in evaluating the soil strength, and how would you influence your design choices?

   Hint

   Think about how each soil type can affect both strength and design choices.

6. 6.

   A recent pavement project faced significant cracking shortly after completion. Investigate potential reasons linking back to soil strength evaluation.

   Hint

   Link performance issues to soil deficiencies and design errors.
