What percentage of pay does the #8 sieve comprise?

The correct answer indicates that the #8 sieve comprises 5% of the total pay factor in asphalt mix specifications. This specific percentage is derived from standard gradation tables and specifications used in asphalt paving projects. In the context of asphalt mixtures, each sieve size corresponds to a certain percentage of the total aggregate gradation.

The #8 sieve, with a certain aperture size, plays a role in influencing the workability, stability, and overall performance of the asphalt mix. Understanding the percentage contribution of different sieve sizes, including the #8 sieve, is crucial for ensuring the mix meets required performance characteristics and conforms to project specifications. This knowledge also aids in the quality control process during mixing and application.

Knowing that the #8 sieve component is 5% assists engineers and contractors in making necessary adjustments to the mixture design, ensuring that the final product is both durable and effective for its intended use.
