The study investigated the physical and rheological properties of asphalt binder modified by polypropylene and cellulose materials. The tests were conducted in the study; conventional tests such as; penetration, softening point and ductility, and unconventional tests such as rotational viscosity and dynamic shear rheometer (DSR). From the conventional tests it found that the hardness of modified asphalt binder with the addition of polypropylene and cellulose materials up to 5%. As a result of increased the hardness the softening point of modified asphalt improved compared with base asphalt binder. The rheological property of modified binders enhanced at low temperatures and high temperatures, as the results of DSR test showed that the G* were improved. The addition of a different percentages of polypropylene and cellulose fibers to base binder had remarkable influence of resistant to permanent deformation (high temperatures rutting and low temperature fatigue).
