Evaluation of Rheological Behaviour of Bitumen Containing Industrial Waste Ashes

The purpose of this paper is to investigate the effect of coal waste ash and rice husk ash on mechanical properties of the stone matrix asphalt mixtures. In this study, of coal waste ash and rice husk ashes was used as a substitute for limestone powder in percentages (0 %, 25 %, 75 %, 75 % and 100 %)in the stone matrix asphalt mixtures. also to prevent drain down of this mixture, the cellulose fibers and SBS polymer fibers were used. in order to investigate the performance characteristics of mixtures the Marshall stability test,  Resilient modulus, indirect tensile strength, moisture  sensitivity, dynamic creep, and wheel tracking tests were performed. the results showed that the replacement of rice husk ash with limestone powder has improved the performance characteristics of the mixture. While the use of coal waste ash is only enhanced the moisture sensitivity of mixtures and it has a negative effect on the performance properties of mixtures.
