摘要: Abstract 100% recycled hot mix asphalt lab samples were modified with five generic and one proprietary rejuvenators at 12% dose tested for binder mixture properties. Waste Vegetable Oil, Grease, Organic Distilled Tall Aromatic Extract reduced the Superpave performance grade (PG) from 94–12 of extracted to PG 64-22 while waste engine oil required higher dose. All products ensured excellent rutting resistance providing longer fatigue life when compared virgin mixtures most lowered critical cracking temperature. Rejuvenated more compaction energy some oils moisture slightly.
