Various specification parameters have been introduced to assess the rutting resistance exhibited by modified bitumen and asphalt mixtures. This study specifically addresses this by examining three distinct types of additives—gilsonite, EVA, and HDPE—each administered at varying dosages. Diverse rutting specification parameters are ascertained for modified bitumen, encompassing G*/sinδ, Jnr, and %R. The evaluation of asphalt mixture rutting resistance is facilitated through measurements of rut depth, utilizing the Hamburg wheel tracking test. Experiments are conducted uniformly at 58 °C across all bitumen and mixture experiments. Employing a dimensionless metric termed the “rutting resistance improvement ratio,” this research systematically explores the relationships between distinct modified bitumen specification parameters and asphalt mixture rut depth. The results endorse Jnr at a stress level of 3.2 kPa as the parameter exhibiting the most robust correlation with asphalt mixture rut depth. This parameter stands as a predictive candidate for assessing the enhancement in asphalt mixture rutting resistance.
