Is the use of larger opening sieves above the #200 sieve required only during Procedure A?

Is the use of larger opening sieves above the #200 sieve required only during Procedure A?

• A. True
• B. False
• C. Only for certain aggregates
• D. It depends on the sample size

Answer: (B)

The correct answer is that the use of larger opening sieves above the #200 sieve is not limited only to Procedure A. In fact, larger sieves are utilized in various testing procedures, not just Procedure A, to accurately assess the particle size distribution of aggregates. This ensures comprehensive analysis and assessment of different material types. In aggregate testing, larger opening sieves play a crucial role in differentiating between various sizes of particles and ensuring that the material meets specified gradation requirements. Therefore, the requirement for larger sieves is based on the standards and procedures applicable to the entire testing flow and not confined to a single method. This approach allows for better characterization and understanding of the material properties involved. The other answer choices do not properly capture the broad applicability of larger sieves across different procedures, making them inadequate in explaining the context of aggregate testing.
