This paper is intended to familiarize asphalt technologists with the unique properties of carbon black and its use as a reinforcing agent for asphalt cements. This effect is obtained with properly selected grades of carbon black. Fundamental differences between carbon blacks and conventional fillers are explained, as well as their different functions in a pavement mix. Theory and practice developed in the extensive use of carbon black as a reinforcing agent for rubber has led to the concept of asphalt reinforcement, and the potential value of carbon black as a new material in asphalt technology. To demonstrate the usefulness of carbon black in asphalt pavements, it was necessary to develop pelleted carbon black products dispersive in asphalts by shearing forces prevailing in normal hot plant operations.
