Question 1.
What is the primary goal of dry mix design?
Show hintHide hint
Think about what stability in pavements requires.
Question 2.
What does gradation help to reduce?
Show hintHide hint
Consider how smaller particles affect the arrangement of larger ones.
3Question 3.
What is the main objective of dry mix design?
- To increase voids
- To achieve maximum density

Show hintHide hint
Reflect on what maximizes stability in a pavement design.
4Question 4.
True or False: Aggregate gradation has no influence on the performance of a bituminous mix.
- True
- False
Show hintHide hint
Consider how better packing might influence performance.
Question 5.
Given a set of aggregates with various gradation limits, outline the process you would follow to achieve a specific gradation within those limits.
Show hintHide hint
Think about the steps from understanding limits to selecting aggregates.
Question 6.
Construct a gradation chart for a hypothetical mix, following Fuller’s law for a defined particle size distribution.
Show hintHide hint
Return to the formula and adjust based on the particle sizes you've chosen.
