• Flat and Elongated Particles - Pavement Interactive

    OverviewBackgroundTest DescriptionResultsThe 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. Flat or elongated particles (Figure 1) tend to lock up more readily (rather than reorient) during compaction making compaction more difficult. They also have a tendency to fracture du
