Investigation of Balanced Feedstocks of Lipids and Proteins To Synthesize Highly Effective Rejuvenators for Oxidized Asphalt

This paper examines the merits of coliquefying high-protein algae with high-lipid swine manure to form a bio-oil containing a high concentration of nitrogen-containing fused aromatics to intercalate into oxidized asphaltene nanoaggregates. Such bio-oils can rejuvenate the aged asphalt found in the reclaimed asphalt pavement by restoring the aged asphalt binder’s original chemical balance and molecular conformation. In this study, several...
