The minimum level at which the aggregates being tested is expected to comply is referred to as what?

• A. Benchmark
• B. Threshold
• C. Standard
• D. Target

Answer: (B)

The idea here is a cutoff that defines the minimum level materials must meet to be considered acceptable. In aggregates testing, the specification sets a lowest acceptable value for a given property, and any result at or above that level is treated as compliant while results below fail. This kind of minimum acceptance value is described as a threshold, because it marks the point beyond which performance is deemed satisfactory. A standard would be the formal rule itself, a benchmark is a reference point for comparison, and a target is an aiming goal—not the required minimum. So the minimum level at which the aggregates are expected to comply is the threshold.
