Prospects of Using Waste Cooking Oil as Rejuvenating Agent in Bituminous Binder

抄録

There are numerous methods being employed for asphalt pavement preservation, such as strengthening the material with various polymers, road pavements impregnation with various oils, road pavement reinforcement with fabric, rejuvenator emulsions, etc. This research work investigates the use of waste cooking oil was as recycling/rejuvenating agent to restore the aged bitumen to a condition that resembles that of the virgin bitumen. The main objective of this paper is to determine some basic characteristics and properties of using waste cooking oil as rejuvenating agent to an aged bituminous binder as compared to original (unaged) bituminous binder. The results showed that there is a remarkable improvement in the properties of the aged bitumen and proved the performance of waste cooking oil as rejuvenator to revive an aged bituminous binder.
