What does the CBR test measure?
Show hintHide hint
Think about resistance to penetration.
Question 2.
Name one laboratory test for evaluating soil strength.
Show hintHide hint
Consider tests conducted on soil samples in a lab setting.
3Question 3.
What is the purpose of the CBR test?
- To measure shear strength
- To determine the bearing capacity of soil
- To assess consolidation properties
Show hintHide hint
Think about soil performance under loads.
4Question 4.
True or False: The DCPT can be correlated with CBR values.
- True
- False
Show hintHide hint
Remember how DCPT results relate to other evaluations.
Question 5.
Given a CBR value of 15%, determine the necessary pavement thickness for a flexible pavement design according to standard guidelines.
Show hintHide hint
Check empirical designs tables for CBR to pavement thickness.
Question 6.
If the UCS of a soil is 300 kPa and the moisture content is increased, predict the potential trend of UCS and explain.
Show hintHide hint
Consider how moisture affects soil behavior.
