Question 1.
What does TSR stand for?
Show hintHide hint
Think of how strength is measured in materials.
Question 2.
Why is moisture susceptibility important?
Show hintHide hint
Consider the impact of water on roads.
3Question 3.
What does a TSR value of 0.8 indicate?
- Good moisture resistance
- Poor moisture resistance
- Excellent durability
Show hintHide hint
Recall the definitions of acceptable TSR values.
4Question 4.
The primary goal of the TSR test is to assess what?
- True
- False
Show hintHide hint
What is the key function of this test?
Question 5.
A pavement mix has a dry tensile strength of 300 psi and a wet tensile strength of 240 psi. Calculate the TSR and determine moisture susceptibility based on standard thresholds.
Show hintHide hint
Use the formula of TSR correctly!
Question 6.
If an engineer wants to improve a pavement mix with a TSR of 0.75, what changes could they consider to enhance moisture resistance? List at least two strategies.
Show hintHide hint
Think about what methods enhance the bond in wet conditions.
