Question 1.
What does the Marshall stability test measure?
Show hintHide hint
Think about the properties of materials under load.
Question 2.
Why is optimum bitumen content important?
Show hintHide hint
Consider the properties that affect road durability.
3Question 3.
What does the Marshall stability test assess?
- Flexibility of the mix
- Load-bearing capacity and flow characteristics
- Cost efficiency
Show hintHide hint
Consider the primary focus of the test.
4Question 4.
True or False: Higher flow values in a Marshall test are always desirable.
- True
- False
Show hintHide hint
Think about the concept of balance in strength and flexibility.
Question 5.
Given a Marshall stability of 620 kg, a flow value of 10 mm, and a mix with 5% bitumen content, how would you assess the suitability for high-traffic areas?
Show hintHide hint
Consider the specifications and compare them to the prescribed limits.
Question 6.
If after testing, your phase diagram indicates that increasing the bitumen content to 6% improves stability but also raises flow beyond desirable levels, how would you adjust your mix design strategy?
Show hintHide hint
Balance is key; always keep the overall performance under review.
