Challenge Problems
Push your limits with challenges.
Question 1
You have two soil samples. Sample A has a PI of 20, and Sample B has a PI of 10. Predict which sample would likely demonstrate higher CBR values.
💡 Hint: Consider plasticity's effect on CBR.
Question 2
During a pavement assessment, you find a correlation chart indicating that DCPT penetration resistance can predict CBR values. If the resistance for a site is recorded at 20 mm, estimate the CBR using the available correlation.
💡 Hint: Use specifics of the provided correlation.
