Several studies were conducted to improve the performance of bituminous concrete mixture in order to minimize the pavement distresses namely permanent deformation and fatigue on the highway pavements. The introduction of polymer modified binder as bituminous paving material was considered as a promising solution in response to increasing traffic wheel loads and changes associated with environmental conditions. Although extensive work was done on polymer modified bitumen, but still there is a need to investigate the modification in terms of their rheological and morphological behavior. The investigation presented herein, is focused on the performance characteristics of the modified binder as revealed by rheological behavior. Rheology of the polymer modified binder is studied in context with its chemical and morphological analysis. This research study is split in two parts. The first part deals with the complete characterization of virgin 80/100 pen bitumen along with polymer modified bitumen (PP & LLDPE). All characterization tests were carried out at ambient temperature and on unaged binders. Only the test for rheological behavior using DSR was conducted on aged and unaged binders. The second part of this study deals with the preparation of specimen for performance testing. All specimens for performance tests were prepared at optimum binder content obtained from Marshall Mix design procedure. For fatigue testing additional plus and minus optimum binder concentration was used.
