The uncertain future of petroleum reserves has fuelled the search for alternative resources. A feasibility study was conducted to determine potential paving applications of the oil extracted from eastern shale by the KENTORT II process. The eastern shale oil (ESO) in this study was separated into two drastically different viscosity portions, designated as 'hard' and 'soft' ESO. It was hypothesized that the 'hard' portion might enhance the asphalt performance by increasing the stiffness. It was discovered that the 'hard' ESO modified asphalt properties deteriorate significantly with time. On the other hand, the 'soft' ESO was found to exhibit desirable properties in an asphalt recycling application. Further studies are recommended to fully characterize the binder and mixture properties of ESO modified/rejuvenated asphalts.
