The maximum size can be determined solely by the largest particle present.

• A. False
• B. True
• C. Not specified
• D. Sometimes

Answer: (A)

Max aggregate size isn’t set just by the largest particle you find. The overall gradation and the mix design determine the largest size that can be used while meeting performance requirements. The sieve analysis defines the upper limit because you need enough smaller particles to fill voids, allow proper compaction, and achieve good coating by the binder. Using a max size based only on the biggest particle can lead to poor workability, insufficient density, or pavement issues, so the design specifies a nominal maximum size that fits the grading envelope. Oversized particles are typically screened out or crushed to fit the design.
