TPO is a project funded by the Circol ELT. The goal of the project was to investigate use of Tyre Pyrolysis Oil (TPO) as an aged bitumen rejuvenator, in an asphalt recycling process and /or as a bitumen substitute. Planned activities focused on laboratory work, specifically focusing on bitumen blend level investigation.
The project work was carried out by Revolution Road Ltd. in collaboration with Kilsaran and Institute of Asphalt Technology – Irish Branch.
Results showed that TPO:
Performs well as aged bitumen rejuvenator,
Optimal content for rejuvenation of aged (recycled asphalt) bitumen is between 6% – 9% of total blend weight.
Test results demonstrated that TPO is suitable bitumen substitute. However, due material health and safety risk, it is necessary to process the TPO further in order to make it safer for handling and environment.

Amir is a Materials Engineer who holds a PhD in Civil/Mechanical Engineering from University College Dublin (UCD), Ireland. He has over 18 years’ experience in asphalt pavement research. During that time, he has been awarded two Marie Skłodowska-Curie Individual Fellowships: (1) the SHARP project – Self-healing Asphalt for Road Pavements (SHARP) and (2) in 2020 for the ASAP Project – Advanced Solutions for Asphalt Pavements (ASAP). He is currently PI and technical expert on two Transport Infrastructure Ireland funded projects investigating the use of bio-inspired technology (self-healing and bio-bitumen) in asphalt mix design. His research focuses on the development of bio-inspired systems for asphalt pavements. He has published widely on this subject. He also works to define and evaluate standards for evaluating self-healing asphalt internationally with the RILEM committee (the International Union of Laboratories and Experts in Construction Materials, Systems and Structures) and nationally with the National Standards Authority Ireland. His career goal is to introduce bio-inspired technology into asphalt pavement design and maintenance processes, with a focus on sustainability and the circular economy. He is currently seeking to commercialise two bio-inspired technologies: i) extrinsic self-healing system and ii) Eco-bind a bio-based product, for asphalt pavement construction and maintenance.
