AGING AND RHEOLOGICAL PROPERTIES OF CARBON BLACK MODIFIED ASPHALT BINDERS

This paper describes how asphalt pavement are used extensively because straight asphalt has the advantage of providing a high-performance road surface at a low cost. However, there are also several disadvantages. The weaknesses of straight asphalt include rutting at high temperature, shrinkage at cold temperature, and embrittlement due to long-term aging. Recently, modified asphalt binders using polymers such as thermoplastic elastomer have been developed in order to overcome these weaknesses. However, there are various restrictions to modified binder application, such as cost, product distribution, and construction management. This paper studies the possibility of employing carbon black (CB) to improve the performance of asphalt pavement. Many researchers have studied CB additives, and previous papers have empirically pointed out the functions of mechanical reinforcement or the effect on temperature susceptibility. Nevertheless, few studies have examined anti-aging performance and failure properties at low temperature, despite the fact that CB is extensively used as an anti-deterioration agent for various polymeric materials, such as rubber tires and wire covering. This paper outlines the anti-aging characteristics of CB for asphalt binders in addition to the reinforcing performance at both high and low temperatures.
