4 cards from this section. Quick, good the night before a test.
What does the crushing test evaluate?
Think about what happens to a material when you apply a heavy weight on it.
What is a maximum aggregate impact value for wearing courses?
Remember, impact means sudden force.
What is evaluated in the crushing test?
Recall what happens when you press down on an object.
Is a high impact value desirable in aggregates?
Consider what happens when something hard hits something else.
Given an aggregate sample fails the soundness test by losing 20% of its weight after five cycles, what does this indicate about its suitability for use in road construction?
Recall the acceptable limits for soundness.
If an aggregate has high flakiness and elongation indices but passes the abrasion and crushing tests, how would that impact its performance in real-world applications?
Think about how shape affects the performance rating.
