AASHTO T27 Sieve Analysis of Fine and Coarse Aggregates Laboratory Testing Service Provided by Eurolab

Standard-Related Information

The American Association of State Highway and Transportation Officials (AASHTO) standards are widely recognized and accepted for ensuring the quality and performance of construction materials, including aggregates. The AASHTO T27 standard specifies the requirements for sieve analysis of fine and coarse aggregates. This test is essential in determining the gradation, fineness modulus, and other properties of aggregates used in various construction applications.

Relevant Standards

  • ISO 13320:2009 - Sieve analysis

  • ASTM C136/C136M-19 - Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates

  • EN 933-1:2012 - Tests for geometrical properties of aggregates - Part 1: Determination of particle size distribution (sieve method)

  • TSE EN 933-1:2009 - Tests for geometrical properties of aggregates - Part 1: Determination of particle size distribution (sieve method)

    • Standard Development Organizations and Their Role

    Standard development organizations, such as AASHTO, ISO, ASTM, and EN, play a crucial role in establishing and maintaining standards for construction materials. These organizations bring together experts from various industries to develop and update standards that ensure consistency and quality.
