Challenge Problems
Push your limits with challenges.
Question 1
You are tasked to design a pavement over a soil with a CBR of 3%. If a similar road in a different location uses a CBR of 15%, discuss the design implications for thickness and materials.
💡 Hint: Think about how the soil's strength impacts material choice.
Question 2
Given that the CBR is essential in preventing pavement failures, propose methods to improve the CBR value of a weak soil subgrade identified during testing.
💡 Hint: Consider how construction techniques can influence soil properties.
