Show hintHide hint
Consider the typical density comparison.
3Question 3.

- 4%
Show hintHide hint
Remember the upper limits discussed.
4Question 4.
Specific gravity values for road aggregates are generally between which ranges?
- 2.0 to 2.5
- 2.5 to 3.0
- 3.0 to 3.5
- 1.5 to 2.0
Show hintHide hint
Associative thinking may help you recall this.
Question 5.
Evaluate a scenario where aggregates with an average specific gravity of 2.3 are used for heavy traffic roads. Analyze possible performance issues.
Show hintHide hint
Assess how density affects load endurance.
Question 6.
Design an experiment to compare the water absorption rates of two aggregate samples. What observations would indicate which one is superior?
Show hintHide hint
Focus on percentage differences in weight before and after immersion.
