“…As the percentage of absorption increases the crystalline phase also increases. Previous research has reported the crystalline behavior of LDPE at 4% by weight of bitumen showed a significant decrease in permanent deformation, fatigue, and thermal crack resistance at high, intermediate, and low temperatures [41]. Another research confirmed that the highly crystalline bitumenmodified mixture can improve the thermal stability of the mixture which has a direct effect on the rheological properties of the asphalt mixture [42].…”

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 (δ), fatigue characteristics G*. Sin (δ), 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 (δ) 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.

“…Their observations revealed that as the LDPE content increased, the binders exhibited improved resistance to rutting under heavy traffic loading and hightemperature conditions. Geckil et al (2022) utilized waste LDPE to modify bitumen, concurrently introducing triethanolamine to establish chemical bonds between bitumen and LDPE. The chemical interaction between waste LDPE, TEOA, and bitumen results in the formation of a homogeneous single-phase structure.…”

Million tons of laminated packaging are extensively used in aseptic food packages due to its merits in transporting and storing liquid foods, and thus a huge amount of waste laminated packaging (WLP) needs to be handled urgently. The main component of the WLP is the cellulose fibers, followed by the low-density polyethylene (LDPE) and aluminum. Previous studies have reported the individual enhancement effect of the LDPE and cellulose fibers as bitumen modifiers. However, the research on the feasibility and effectiveness of using WLP as a bitumen modifier is limited. In this study, WLP manually collected from milk and fruit juice packages was processed into particles. The performance of bitumen modified by WLP was characterized and compared with that of base bitumen by conventional and rheological tests. The testing results showed that the addition of WLP increases the softening point and peak force, and decreases the penetration and ductility. Meanwhile, a higher WLP content led to a greater modification index, higher failure temperature, lower non-recoverable creep compliance and lower stress sensitivity. Furthermore, the stabilizing effects of LDPE and the sufficient crosslinking of the cellulose fibers are beneficial to the fatigue life of bitumen.

“…To address these issues, bitumen modifiers, e.g. styrene-butadienestyrene (SBS), lowdensity polyethylene (LDPE), reactive terpolymers or biowaste have been developed to enhance the durability and performance of pavinggrade bituminous binders [4][5][6][7][8][9]. To improve bitumen properties and thus broaden its application, polymer additives are by far the most commonly used modifiers in this respect.…”
