Question 1.
What is the primary assumption of the layered elastic model?
Show hintHide hint
Think about how material properties are viewed in this model.
Question 2.
Explain the significance of understanding stress and strain in pavement engineering.
Show hintHide hint
Stress and strain are foundational concepts in material mechanics.
3Question 3.
What does the layered elastic model assume about pavement layers?
- They vary in composition
- They are homogeneous and isotropic
- They behave non-linearly
Show hintHide hint
Think about simplicity in modeling.
4Question 4.
True or False: Visco-elastic models are not used in pavement design.
- True
- False
Show hintHide hint
Consider the behavior of materials over time.
Question 5.
Evaluate how you would choose between a layered elastic and a visco-elastic model for a specific project involving a highway that experiences both heavy truck loads and varying temperatures.
Show hintHide hint
Consider both immediate and sustained loads and how they relate to temperature effects.
