1. Soil Classification for Pavement Engineering

Try these first

1. 1.

   Define soil classification.

   Hint

   Think about how we group soil types for engineering purposes.

2. 2.

   List two soil classification systems.

   Hint

   Consider the systems discussed in class.

3. 3.

   What is the purpose of soil classification in pavement engineering?

   • To assess soil load-bearing capacity
   • To change soil type
   • To reduce soil moisture

   Hint

   Think about why engineers assess soil strength.

4. 4.

   True or False: The USCS categorizes soil strictly based on its organic content.

   • True
   • False

   Hint

   Consider what USCS mainly focuses on.

5. 5.

   You are tasked with designing a pavement structure over a stretch with mixed soil types. Propose a soil testing strategy that would help you ensure adequate load-bearing capacity and minimal deformation over time.

   Hint

   Consider both short-term and long-term testing methods.

6. 6.

   Evaluate the implications of using expansive clay soils (like black cotton soils) in pavement foundations. What stabilization measures would you recommend?

   Hint

   Think about both immediate and long-term soil behavior.
