2 cards from this section. Quick, good the night before a test.
What does the Crushing Strength Test evaluate?
Think about what aggregates need to withstand in road construction.
What is an acceptable ACV for wearing surfaces?
Recall the specifications mentioned during our discussions.
What does the Crushing Strength Test primarily measure?
Consider what aspect of aggregates this test evaluates.
True or False: A lower Aggregate Crushing Value indicates a stronger aggregate.
Think about how strength is represented in numbers.
An aggregate tested has an original weight of 1000g and a residual weight of 600g after testing. What is the ACV, and is it suitable for a high-traffic road?
Use the ACV formula discussed in the classroom.
Analyze two different aggregates: Aggregate A with an ACV of 25% and Aggregate B with an ACV of 35%. Which is suitable for a wearing surface, and why?
Consider the specifications for wearing surfaces.
