The correct answer, which states that the #200 sieve constitutes 10% of pay, is based on the specifications and guidelines used in asphalt mixes, particularly in relation to the aggregate gradation. The #200 sieve is crucial in asphalt paving because it determines the amount of fines in the mixture, which can significantly affect the stability, workability, and overall performance of the asphalt.

In standard specifications, the percentage of material passing through the #200 sieve is often weighted to assess the quality of aggregate used. This percentage contributes to the calculation of the overall asphalt mix's strength and durability. Adhering to these specifications ensures that the asphalt is designed to perform adequately under traffic loads and environmental conditions.

The figure of 10% reflects a commonly accepted standard within the industry, which aids in determining the appropriateness of the aggregate blend used in asphalt mixtures. This pay percentage shows how essential it is for the gradation to be within set limits, influencing the quality and life span of the pavement constructed. Understanding this linkage between sieve size, material properties, and performance characteristics is foundational knowledge for anyone involved in asphalt paving and quality assurance.
