Utilization of Waste Engine Oil to Enhance the Ageing Resistance of Asphalt Binder

Abstract

The purpose of this research is to access and simulate the ageing response when a specific neat binder typically used in asphalt pavements, is subjected to extended short-term ageing effect due to long hauling distances and unexpected traffic interruptions. Furthermore, this study is purposed to identify the optimal dosage of an abundantly available waste material (i.e., Waste Engine Oil) for rejuvenation of the extended short-term aged binder. The results of this study reveal that the binder’s basic properties of penetration, softening point, ductility, flash point and viscosity are recovered by 81.7%, 100%, 100%, 92 & 89.7%, and 87.4% with respect to virgin binder when 10% Waste Engine Oil (by weight of bitumen) is added in extended short term aged asphalt binder. This research can be further extended to utilize the long-term aged asphalt binder recovered from recycled asphalt pavement (RAP) resulting in a sustainable solution.
