Question 1.
What is workability in bituminous mix design?
Show hintHide hint
Think about how easy it is to handle the materials.
Question 2.
Name one factor that affects the workability of a mix.
Show hintHide hint
Consider the materials used in the mix.
3Question 3.
What factor primarily affects the workability of a bituminous mix?
- Aggregate gradation
- Temperature
- Traffic load
Show hintHide hint
Consider the sizes of the particles used in the mix.
4Question 4.
True or False: Higher bitumen content always improves workability.
- True
- False
Show hintHide hint
Think about the consequences of too much fluidity.
Question 5.
You are tasked with designing a bituminous mix with a high level of workability. What specific gradation of aggregates would you choose and why?
Show hintHide hint
Think about how size distributions interact.
Question 6.
In an experiment, you found that increasing the angularity of aggregates leads to a drop in workability. Propose a solution to mitigate this issue.
Show hintHide hint
Reflect on the mix composition and the types of aggregates.
