Show hintHide hint
Think about the least dimensions of particles.
Question 2.
Define the elongation index.
Show hintHide hint
Focus on the longest dimension of aggregate particles.
3Question 3.
What does the flakiness index assess in aggregate testing?
- Proportion of spherical particles
- Proportion of flaky particles
- Proportion of elongated particles
Show hintHide hint
Focus on the definition of flakiness.
4Question 4.
True or False: The elongation index is applicable only to aggregate particles larger than 6.3mm.
- True
- False
Show hintHide hint
Think about the size limitations.
Question 5.
If given a sample of aggregate with a flakiness index of 35% and an elongation index with no established limits, how would you assess its suitability for pavement?
Show hintHide hint
Consider how flakiness affects performance.
Question 6.
Propose a strategy to ensure that the aggregates used in a new pavement project remain within the optimal flakiness and elongation indices. What measures would you suggest?
Show hintHide hint
Think about regular testing and quality control.
