dc.description.abstractThe inherent characteristics of asphalt binder can pose challenges to achieving a flexible pavement with the desired properties. However, these challenges can be addressed through asphalt modification. While numerous additives are available, selecting the most suitable one is crucial due to issues such as cost, storage stability, and homogeneity. This study focused on evaluating the physical and rheological properties of an asphalt binder modified with a hydrocarbon-based thermoplastic resin. The investigation included conventional binder tests and rotational viscometer (RV) analysis, along with an in-depth rheological evaluation of the modified binders using a dynamic shear rheometer (DSR). Additionally, the thermal properties of the additive were analyzed through thermogravimetric analysis (TGA). The findings revealed that the modified binders exhibited reduced penetration, elevated softening points, and increased viscosity, all achieved without compromising workability or pumpability. Furthermore, the modification enhanced rutting resistance. Laboratory tests identified 5% as the optimal additive content, which improved the performance grade of the pure binder. Activation energy results derived from the complex viscosity master curves indicated that while the energy required for flow increased with the addition of 5% resin, the elevated viscosity mitigated the temperature sensitivity issue observed in the pure binder.
