Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Review the permissible limits for different pavement types.

Question 2

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.

💡 Hint: Think about how abrasion values guide material selection.
