Question 1.
What is aggregate gradation?
Show hintHide hint
Think about how the sizes of aggregates relate.
Question 2.
Why is density important in asphalt mixtures?
Show hintHide hint
Consider the impact of weight in materials.
3Question 3.
What is the main purpose of effective aggregate gradation?
- To maximize void space
- To achieve maximum density
- To minimize particle size
Show hintHide hint
Remember the relationship between density and stability.
4Question 4.
True or False: Some void space is necessary in a bituminous mix.
- True
- False
Show hintHide hint
Consider the role of binder materials.
Question 5.
Suppose you have a mixture with a gradation that is too coarse. How could this affect the performance of the paving?
Show hintHide hint
Think about how well the materials fit together.
Question 6.
Given the aggregate sizes, create a mixed design approach for a specific pavement project. What considerations will affect your choice?
Show hintHide hint
Remember the practical applications discussed during our sessions.
