Assessing the Role of Extender Oil in Enhancing the Physical Properties of Green Asphalt Binder

Saad Issa Sarsam

Abstract


In Iraq, the asphalt cement is produced as a byproduct during the crude oil refining process. The produced asphalt cement does not practice any further processing which is required to control its chemical composition and physical behavior. It was felt that incorporation of additives can enhance its sustainability and reserve the required physical properties of green asphalt binder. This work demonstrates the implementation of extender oil (used oil) and scrap tire rubber in the wet process to improve the quality of the asphalt cement and provide a sustainable and proper quality of the binder for green paving work. It was observed that a combination of various percentages of rubber and extender oil had provided a suitable control on the penetration, softening point, viscosity, and ductility of the binder. The expected stiffness of asphalt concrete was improved and provides a suitable resistance to deformation at cold, moderate, and hot environment. Implication of 15 % scrap tire rubber and 10 % of extender oil into the asphalt cement from Qayarah is recommended as a sustainable green binder for pavement.
