  • EVALUATION OF THE EFFECT OF FLAT AND ELONGATED PARTICLES

    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 specifies a maximum limit of 10 flat and elongated particles at the 5 1 ratio for the design aggregate blend.
