Abstract

This paper investigates the viability of using solvent, Toluene, to increase the dispersion of the Epoxidized natural rubber ENR and use it as a modifier with bitumen. 5% ENR by weight of bitumen was blended with 80/100 paving grade asphalt under optimum temperature and mixing time. Two methods of mixing were used, the first one was done with using of high shear mixer equipment and coded as (HSMP), and the other was done with using of low shear mixer, and Toluene as solvent, and coded as (LSMP). Unmodified and modified bitumen were subjected to many tests by using the dynamic rheometer shear (DSR) for unaged, short and long term aged binders to observe the effects of the solvent on the bitumen binder. The performance tests including Rheological analysis, morphology, penetration, softening point and ductility tests were carried out on unmodified and modified bitumen. It was observed that adding Toluene to the bitumen doesn't really change the Rheological properties of the virgin bitumen. The results showed increasing in complex modulus G*, decreasing in phase angle δ and improving in dispersion of ENR in bitumen with using of LSMP. This indicates that using of solvent can improve the modified bitumen performance without deteriorating the physical properties of bitumen for short and long term.
