Question 1.
What does CBR stand for?
Show hintHide hint
Think about what CBR measures.
Question 2.
Which chart do you use for traffic loads of 5 msa?
Show hintHide hint
Recall the traffic ranges defined earlier.
3Question 3.
The CBR is a measure of:
- Pavement thickness
- Subgrade strength
- Traffic load
Show hintHide hint
Think about what the CBR test evaluates.
4Question 4.
Using Chart 2 is necessary for traffic loads of:
- True
- False
Show hintHide hint
Recall which traffic loads correspond to which chart.
Question 5.
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.
Show hintHide hint
Look carefully at the upper limits of traffic loads mentioned in the charts.
Question 6.
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.
Show hintHide hint
Consider the interplay of design assumptions against actual conditions observed after construction.
