Rheology and Performance Evaluation of Modified Asphalt Binders with Elastomer and Plastomer

Asphalt modification has played a crucial role in improving mechanical characteristics of asphalt mixtures, thereby enhancing performance and extending service life of the asphalt pavements. Different combinations of SBS and LDPE modifier concentrations were investigated in this study. Conventional properties, rutting and fatigue behavior were obtained to evaluate performance-related properties of the modified binders. The results show that the LDPE plastomer was more effective on reducing penetration than the SBS elastomer. The SBS elastomer appeared to be less thermal susceptible than the LDPE plastomer over a wide range of test temperatures in terms of G* master curve. The BYET with method A shows the binder with 2% SBS + 4% LDPE possessed the highest yield energy together with maximum shear stress values. The higher yield energy suggested an elevated resistance to fatigue of the modified binders. The addition of SBS elastomer to asphalt would significantly increase the elastic recovery behavior of binders compared to the LDPE plastomer based on the BYET method B. The elastomer had greater contribution to fatigue cracking compared to the modified binder with plastomer in terms of LAS results. The binder with 6% SBS possessed the highest numbers of loading cycle to failure. The addition of SBS elastomer to asphalt binder would help to improve the elastic response at higher temperatures compared to the inclusion of LDPE plastomer. It is concluded that the binder with 6% SBS had good performance in fatigue, while binder with 2% SBS + 4% LDPE represented the well resistance to permanent deformation.
