The efficacy of polymers on the various performance parameters of modified bitumen was investigated. For PG 64-22, three distinct kinds of polymers with distinct ratios—3.5 %, 8 %, and 1.5 % by weight of base bitumen, respectively—were manufactured, each of which was deemed to have a high effectiveness on properties by local experts. These polymers ratios were as follows: The four samples, three of which had their physical qualities and storage stabilities examined using traditional methods, were changed using Butonal NS, PR Plast, and Titan Polymers. In addition, experiments for both short-term and long-term aging processes were carried out using a rolling thin film oven as well as a pressure aging vessel. In order to evaluate the bitumens rheological characteristics, a rotating viscosity and bending beam rheometer was used. Following the rheological analysis, the essential kind of road asphalt mix was developed so that it could be tested for rutting. According to the findings, all three varieties of polymer-modified bitumen give an improvement in the rheological and physical characteristics of bitumen, as well as a strong resistance against rutting. Furthermore, it was discovered that they are very compatible with base bitumen. The viscosity and stiffness of the bitumen were greatly improved by the addition of polymers.
