AASHTO T 30-21 PDF Download

The AASHTO T 30-21 standard provides a standardized method for determining the particle-size distribution of extracted aggregate. This standard specifically applies to both fine aggregates and coarse aggregates obtained from hot mix asphalt (HMA). The method involves the use of sieves with square openings to analyze the sizes of the particles in the aggregate.

The procedure outlined in the standard ensures consistency and accuracy in determining the particle-size distribution of the extracted aggregate. This information is crucial in evaluating the quality of the aggregate and its suitability for specific applications. By following the guidelines set forth in AASHTO T 30-21, practitioners can obtain reliable data on the sizes of particles present in the aggregate.

This standard is an important tool for professionals and laboratories involved in the analysis of aggregate samples. It enables them to perform mechanical analysis and generate data that can be used for design, construction, and quality control purposes. Adhering to the AASHTO T 30-21 standard ensures uniformity and reliability in the determination of particle-size distribution in extracted aggregate samples.
