Flat and elongated particles have long been considered undesirable in hot mix asphalt (HMA) mixes due to their tendency to break down during construction and traffic. Currently, the Superpave mix design system currently specifies a maximum limit of 10 percent of flat and elongated particles at the 5:1 ratio for the design aggregate blend.
Caltrain Standard Specifications September 30, 2011 BALLAST AND WALKWAY AGGREGATE B. Ballast/walkway aggregate shall be crushed stone broken by the crusher and have at least 2 broken surfaces: angular, rough-surfaced, clean and free of sand, loam, clay, flat, elongated, soft or disintegrated pieces, and other deleterious substances.

1.1 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. Method A is a reflection of the original procedure as developed prior to Superpave and is intended for all non-Superpave applications.

indicated that the smaller particles, in the case of the diameter ratios greater than 0.22, would be too large to fit in the interstices between the large particles. Such models directly deal with aggregate particle sizes and packing orders to dictate density and air void content of a granular assembly.
