The objectives of this paper is to highlight the study conducted to explore the performance grade (PG) of asphalt produced in the Gulf Countries (GCs) and the polymer modification of these binders using local and commercial polymers. The results indicated that the properties of the GCs' asphalt can be significantly upgraded by adding polymers. The rheological analysis of the modified asphalt indicated an increasing performance and improved properties. The final properties were found to be dependant not only on the polymer type, but also on the asphalt type. Also some important parameters for the modification process were determined including: blending time, blending temperature, and polymer content. In general, the results have shown the effectiveness of the polymers in modifying performance behavior of the GCs' asphalts.
