Agricultural By-Products, Biowastes, and Other Biogenic Materials as Bio-Rejuvenators for Aged Bituminous Binders: Mechanisms, Performance, and Challenges.
Review in Polymers, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Asphalt binders become stiffer and more brittle during aging, increasing their susceptibility to fatigue and thermal cracking. Rejuvenation is therefore a key strategy for restoring aged bitumen and enabling the effective use of reclaimed asphalt materials. This review examines agricultural by-products, biowastes, and other biogenic materials as bio-rejuvenators for aged bituminous binders. The reviewed materials are classified according to their source, processing route, functional role, chemical characteristics, rejuvenation mechanism, performance effects, and practical limitations. The main groups include waste cooking oils, virgin vegetable oils, reactive bio-oils, biomass-derived bio-oils, agricultural and forestry residues, tree-resin-derived products, animal-based rejuvenators, and other organic waste-derived materials. The literature indicates that these materials can restore aged bitumen through light fraction replenishment, colloidal rebalancing, diffusion, asphaltene deagglomeration, chemical interaction, and anti-aging effects. Waste cooking oils and agricultural/forestry residue-derived rejuvenators provide particularly strong recovery of conventional binder properties, whereas reactive bio-oils and tree-resin-derived systems offer a more balanced rheological response and cracking-rutting balance. However, their effectiveness strongly depends on dosage, feedstock variability, binder compatibility, processing route, and aging condition. Overall, bio-rejuvenators offer a promising pathway for sustainable asphalt recycling, but their practical implementation requires standardized dosage selection methods, long-term aging assessment, mixture- and field-scale validation, and life-cycle evaluation.
