FLEXURAL FATIGUE CHARACTERISTICS OF ASPHALT CONCRETE WITH CRUMB RUBBER

This paper describes an investigation into fatigue of asphalt concrete modified by addition of crumb rubber as a part of the aggregates. Flexural fatigue tests on asphalt concrete and rubber modified asphalt concrete conducted at 20, 25, and 30 degrees C under constant strain mode indicated that the fatigue life of rubber modified asphalt concrete is significantly higher than that of the plain asphalt concrete. Design charts are presented to show that the pavement with rubber modified asphalt concrete requires a lower design thickness.
