Challenge Problems
Push your limits with challenges.
Question 1
A new highway is expected to carry 100 msa with an average subgrade CBR of 5%. Calculate the required pavement thickness using the appropriate chart and discuss any potential issues with this design.
💡 Hint: Look carefully at the upper limits of traffic loads mentioned in the charts.
Question 2
If you see a failure in the pavement structure, how would you assess whether the thickness was appropriate? Consider factors like CBR, traffic predictions, and material quality in your response.
💡 Hint: Consider the interplay of design assumptions against actual conditions observed after construction.
