Flat and Elongated Particles Pavement Interactive

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.
