Improving recycled asphalt using sustainable hybrid rejuvenators with enhanced intercalation into oxidized asphaltenes nanoaggregates

This paper introduces a new bio-rejuvenator made from a blend of high-protein algae and high-lipid animal manure and studies its interaction with aged bitumen molecules to revitalize aged asphalt. True revitalization requires restoring not only the chemical balance but also the molecular conformation. Therefore, rejuvenators should be able to de-agglomerate oxidized asphaltenes while compensating for components that are lost during aging. This...
