Influence of Coal Combustion By-Products Physiochemical Properties on Aging Related Performance of Asphalt Mastics and HMA
In this study, five CCPs (coal combustion products) are used in asphalt mixtures such that 10% of the asphalt binder is replaced with the CCP without changing the mix design. The study used laboratory testing to monitor any change in performance compared to a control blend. Testing focused on aging related distresses, such as fatigue, and low temperature performance. Mixture samples are exposed to long term aging before conducting the performance related tests. The results show that mixture volumeetrics, mechanical performance, and aging related performance show significant improvement when 10% of the binder is replaced by the CCPS. Statistical analysis show that the improved performance is correlated to the CCP physiochemical properties.
