AB  - This research is aimed at investigating the mechanical behavior of the bitumen by 
      the addition of high-density polyethylene (HDPE) and low-density polyethylene 
      (LDPE) obtained from waste plastic bottles and bags. Polymers (HDPE and LDPE) 
      with percentages of 0%, 2%, 4%, and 6% in shredded form by weight of bitumen were 
      used to evaluate the spectroscopic, structural, morphological, and rheological 
      properties of polymer-modified binders. The rheological properties for different 
      factors; viscosity (ἠ) from Rotational Viscometer (RV), rutting factor G*/Sin 
      (delta), fatigue characteristics G*. Sin (delta), for the modified binder from dynamic 
      shear rheometer (DSR), Short and long-term aging from rolling thin film oven 
      (RTFO), and pressure aging vessel (PAV) was determined. The thermal 
      characteristics, grain size, and texture of polymers for both LDPE and HDPE were 
      found using bending beam rheometer (BBR) and X-ray diffraction (XRD), 
      respectively. Fourier transform infrared (FTIR) analysis revealed the presence of 
      polymer contents in the modified binder. Scanning electron microscopy (SEM) 
      images revealed the presence of HDPE and LDPE particles on the surface of the 
      binder. Creep Rate (m) and Stiffness (S) analysis in relationship with 
      temperature showed a deduction in stress rate relaxation. Results have revealed 
      the best rutting resistance for 6% HDPE. It also showed an improvement of 95.27% 
      in G*/Sin (delta) which increased the performance of the bituminous mix. Similarly, 
      the addition of 4% LDPE resulted in maximum dynamic viscosity irrespective of the 
      temperatures. Moreover, fatigue resistance has shown a significant change with 
      the HDPE and LDPE. The festinating features of waste plastic modified binder make 
      it important to be used in the new construction of roads to address the high 
      viscosity and mixing problems produced by plastic waste and to improve the 
      performance of flexible pavements all over the world.
