Highlights Pyrolysis and liquefaction (HTL) of biomass are compared to produce biobinders. HTL provides a more stable product in high yield with relatively low oxygen content. Biobinders performance depends on the biomass source and the technology applied. Long-term performance and environmental impact studies for biobinders are missing. Tables compiled from the literature are provided to identify suitable biobinders.
Abstract Biobinders (binders manufactured from biomass) are becoming popular in asphalt engineering due to growing environmental concerns of greenhouse gas emissions from the use of fossil fuels and depleting petroleum bitumen reserves. Waste biomass products are sources of particular interest due to their widespread availability and impact on sustainability, however, they generally need to be thermochemically treated before being used as biobinders. Although biobinders can exhibit good performance in terms of resisting common distresses affecting road pavements, they are still relatively unknown and the uncertainty around them discourages their further use. In this context, this review aims at providing a link between biomass thermochemical conversion technologies and their respective products that may be used as biobinders in pavement engineering. For this purpose, firstly, a detailed insight of the biomass thermochemical conversion technologies available for the manufacture of biobinders is provided. Specifically, solvent liquefaction and pyrolysis are compared and the operating parameters affecting the production of biobinders from solvent liquefaction are explored. Secondly, the review focuses on providing an overview of current biobinder studies for asphalt mixtures with an emphasis on the feedstock utilised and their key engineering properties. The review shows that biobinders’ performance highly depends on the biomass source and the technology applied to produce them. Summary tables provide researchers with a quick but insightful way of identifying potential biobinder feedstocks according to certain properties.
