Effect of Coal Combustion Products on high temperature performance of asphalt mastics

The investigation of the rheological performance of asphalt binders with different types of CCPs using Dynamic Shear Rheometer (DSR) confirmed the feasibility of using these by-products to improve the permanent deformation resistance of asphalt binders. Research data demonstrate that the effect of the CCPs is dependent on the dosage and physical and chemical properties of CCP. Based on the rheological response of CCP based mastics at high temperatures this study found a strong physical and chemical interaction between the CCP and the asphalt binder.
