Rheological investigation on the ageing performance of bio-recycled asphalt binders and mixtures Jiménez Del Barco Carrión, Ana Lo Presti, Davide Chailleux, Emmanuel Airey, Gordon The research presented in this paper received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no. 607524, and the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 754446 and UGR Research and Knowledge Transfer Found – Athenea3i. The current need to move towards more sustainable technologies in the construction sector has promoted the investigation of using alternative materials in asphalt mixtures for pavements. Biomaterials, used as biobinders, have shown their potential as partial replacement of bitumen in asphalt mixtures as solution to decreasing the demand for fossil-fuelbased binders as well as CO 2 emissions. However, more research is needed to increase the replacement of bitumen in asphalt mixtures. In this investigation,biobinders are used as full replacement of virgin bitumen and as recycling agent within asphalt mixtures with high Reclaimed Asphalt (RA) content. Blends of biobinders and RA binders, and bio-recycled asphalt mixtures, were produced, subjected to ageing and rheologically characterised. The results show that the rheological properties of binders’ blends seem adequate for their use, while the bio-recycled asphalt mixtures seem to have a faster ageing than conventional ones, hence their full-scale application still remains a concern. 2025-01-29T12:58:56Z 2025-01-29T12:58:56Z 2023 journal article Ana Jiménez del Barco Carrión, Davide Lo Presti, Emmanuel Chailleux & Gordon D.
