Question 1.
What is the main purpose of the Los Angeles abrasion test?
Show hintHide hint
Think about the importance of materials' resistance to friction.
Question 2.
What does a lower Los Angeles abrasion value indicate?
Show hintHide hint
Consider how this affects road durability.
3Question 3.
What did the abrasion test measure?
- A. Thickness of the aggregate
- B. Hardness and durability
- C. Weight of the aggregate
Show hintHide hint
Think about the impacts of wear on aggregates in road construction.
4Question 4.
True or False: A Los Angeles abrasion value over 40% is acceptable for a water-bound macadam base course.
- True
- False
Show hintHide hint
Consider the quality thresholds for construction materials.
Question 5.
Given an aggregate sample subjected to the Los Angeles abrasion test that results in a 38% loss in weight, discuss its suitability for use in a bituminous concrete project with supportive reasoning.
Show hintHide hint
Review the permissible limits for different pavement types.
Question 6.
You have two aggregate samples, one with a 30% and another with a 50% Los Angeles abrasion value. Discuss which sample is preferable for construction and why.
Show hintHide hint
Think about how abrasion values guide material selection.
