Question 1
A contractor is using soil with a CBR value of 15% for road construction. What implications does this have for the thickness of pavement required?
💡 Hint: Think about how the strength of the soil impacts design choices.
Question 2
During a CBR test, the 2.5 mm penetration ratio was found to be 45%, and the 5 mm ratio was higher than that. If repeated testing confirms this, what CBR value should be reported?
💡 Hint: Refer to how we handle differing CBR values from test results.
