The number of flat and elongated particles is counted for each aggregate, and the percentage of flat and elongated particles is then calculated (9). Automated Testing for Flat and Elongated Particles. Automated testing and analysis techniques are versatile tools for characterizing shape parameters of aggregates.
Standard Test Method for Flat Particles, Elongated Particles, or Flat and Elongated Particles in Coarse Aggregate. This test method covers the determination of the percentages of flat particles, elongated particles, or flat and elongated particles in coarse aggregates. Two procedures, Method A and Method B, are presented in this standard.
Flat and Elongated Particles • Overview • The flat and elongated particle test is used to determine the dimensional ratios for aggregate particles of specific sieve sizes. This characterization is used in the Superpave specification to identify aggregate that may have a tendency to impede compaction or have difficulty meeting VMA specifications due to aggregate degradation.
