  • Abstract:
    The effect of aggregate characteristics on the fatigue behavior of asphaltic mixtures was investigated by utilizing a laboratory constant deflection, flexural fatigue test. Coarse aggregate characteristics such as surface texture, rugosity, and flakiness index, were evaluated and attempts were made to correlate these with fatigue behavior. Since previous work had indicated that aggregate shape and roughness could affect the fatigue life, it was hoped that the particle index, which accounts for all aggregate physical characteristics, would correlate with fatigue life. No correlation between particle index and fatigue life was found; however, extremely high values, of particle index may indicate a tendency toward low fatigue life. There was no significant difference in the fatigue behavior of a mixture containing limestone aggregate and one containing limestone aggregate on which the surface texture had been roughened by acid etching. Although high values of rugosity and flakiness can indicate a predicted low fatigue life, low values do not necessarily predict normal or high fatigue life.
