title = "Characterization of damage and aging resistance of asphalt mastics with coal combustion by-products",
abstract = "In this study, two asphalt binders are blended with four particulate types; one natural filler and three Coal Combustion By-Products (CCPs), to make mastics at different concentrations. This initial study aims to evaluate the compatibility of different asphalt binders with these particulates in terms of damage and aging resistance. High and intermediate temperature testing is conducted while varying the aging level. Results show tha the particulates, at all concentrations, improve high temperature rutting resistance of mastics. At intermediate temperature, the results show significant dependency on particulate, binder and polymer modification types. In general, results show that CCP mastics with unmodified binders increase damage resistance at high temperature, with no determinate effect on aging related stiffness. For the polymer modified binder, Spray Dryer Absorber (SDA) appears to enhance its properties significantly as noticed by increase damage resistance, recovery, and significant retardation in aging related stiffness.",
