Abstract
Treating aged asphalt includes contacting aged asphalt with a bioagent to yield a mixture. The aged asphalt includes a siliceous stone component and bitumen, and the bioagent includes bio-oils formed from hybrid biomasses. The siliceous stone component and the bitumen are separated. The bioagent promotes separation of the siliceous stone from the bitumen. A rejuvenated bitumen composition includes recycled bitumen, virgin bitumen, and a bioagent. The recycled bitumen can be produced from recycled asphalt paving, and the bioagent can include bio-oils formed from hybrid biomasses.
