Question 1.
What does the Rutting Model predict?
Show hintHide hint
Think about what happens to roads under vehicles.
Question 2.
What kind of weather impact does the Thermal Cracking Model address?
Show hintHide hint
Consider what happens to materials when it gets extremely cold.
3Question 3.
What does the Rutting Model primarily focus on?
- Permanent deformation from traffic
- Temperature impacts on asphalt
- Cost of pavement materials
Show hintHide hint
Remember the effects of heavy traffic on roads.
4Question 4.
True or False: The Fatigue Cracking Model is used to predict stress from low temperatures.
- True
- False
Show hintHide hint
Think about what each model specifically addresses.
Question 5.
Design an asphalt mix for a highway in a region with high traffic and cold winters. Consider all three Superpave models in your recommendations of material properties.
Show hintHide hint
Balance all three aspects based on anticipated environmental conditions.
Question 6.
Evaluate a pavement section that has experienced extensive rutting and cracking. Using the Superpave models, explain how you would assess and propose rehabilitations for the section.
Show hintHide hint
Investigate specific failures and map out a holistic solution based on predictive modeling.
