Question 1.
What does a higher CBR value indicate about pavement thickness?
Show hintHide hint
Think about the soil's bearing capacity.
Question 2.
Define the resilient modulus.
Show hintHide hint
Remember it relates to traffic loads.
3Question 3.
What does a higher CBR percentage imply for pavement thickness?
- Thicker pavement is needed
- Thinner pavement can be used
- CBR has no effect
Show hintHide hint
Remember 'Higher CBR, Thinner Pavement'.
4Question 4.
True or False: Resilient Modulus (MR) can be estimated from CBR values.
- True
- False
Show hintHide hint
Think of the relationship between CBR and MR in design.
Question 5.
Given a soil sample with a CBR of 20%, calculate the approximate Resilient Modulus (MR). What would this imply for pavement design?
Show hintHide hint
Remember the relationship between MR and CBR.
Question 6.
Discuss the impact of seasonal changes on UCS and suggest methods to mitigate these effects in pavement design.
Show hintHide hint
Consider how water management is critical for soil stabilization.
