Investigating the Practical Application of an Asphalt Mixture Using Lignin to Replace a Portion of the Asphalt Binder
In order to achieve carbon-neutral pavements, this study investigated the practical application of the bio-asphalt mixture using kraft lignin derivatives to replace a portion of the asphalt binder. The lignin used in this study is a by-product of the paper-making process. When the lignin-based asphalt with 35% volume replacement of the binder with lignin is applied, the CO₂ emissions from the manufacturing of bio-asphalt mixture may be theoretically reduced by 96.6% compared to that of the conventional asphalt mixture. Currently, the laboratory experiments demonstrated the bio-asphalt mixture using 10% volume replacement of the binder with lignin had properties which were equivalent to conventional asphalts. In particular, replacing 10% volume of the binder with lignin may improve the rutting resistance and the fatigue resistance of the mixture. Furthermore, the field verification of the bio-asphalt mixture was conducted on a road with heavy vehicles, and the mixture showed excellent performance in serviceability.
