Effect of recycling agents on rheological properties of epoxy bitumen

The rejuvenation of epoxy modified bituminous binders is a topic much debate because such may not be able to melt at high temperatures and restore their properties using recycling agents. This paper presents the results an experimental program developed evaluate re-usability bitumen, or by three agents: aromatic-based agent, aliphatic-based soft binder. impact these agents on response aged was assessed performing analyses in Fourier Transformed Infrared spectroscopy Dynamic Shear Rheometer. Results indicated that diluting binder with base bitumen can feasible method for producing aging resistant long curing time lengths. most severely oxidized samples were blended agents, aromatic agent has been proved as effective recover rheology binders. Significant potential relaxation characteristics demonstrated As result, shown similar ‘rejuvenation’ attribute conventional thus, it might re-utilized through standard asphalt processes.
