Examining the Implications of Wax-Based Additives on the Sustainability of Construction Practices: Multiscale Characterization of Wax-Doped Aged Asphalt Binder

Paraffin wax is a component of many additives and rejuvenators commonly used in the asphalt industry to promote sustainability by facilitating recycling and/or reducing mixing and compaction temperatures during pavement construction. However, the effect of wax-based additives on asphalt molecules and consequently on asphalt binder’s performance characteristics has not been thoroughly understood. This paper uses a combination of a computational...
