Question 1.
What does the crushing test measure?
Show hintHide hint
Think about the forces aggregates face in pavements.
Question 2.
What is a good ACV value for aggregates?
Show hintHide hint
Remember the scale provided for ACV values.
3Question 3.
What is the main purpose of the crushing test?
- To measure resistance to water absorption
- To determine resistance to compressive stress
- To evaluate aggregate shape
Show hintHide hint
Think about what happens when weight is applied to material.
4Question 4.
Is an ACV of 5% considered strong?
- True
- False
Show hintHide hint
Remember what ACV values signify strength.
Question 5.
Analyze two types of aggregates, one with an ACV of 6% and another with 37%. Predict the implications for their use in a high-traffic highway.
Show hintHide hint
Reflect on the implications of strength on longevity in road usage.
Question 6.
Design a small-scale experiment to measure the crushing value of a new aggregate source. Detail the steps and expected outcomes.
Show hintHide hint
Consider each step carefully, including measuring and applying the standard load.
