To lessen the harmful impact of waste products on the environment and nature, it seems reasonable to introduce a method of reuse of waste materials in engineering projects and construction projects, for example, road construction to enhance the asphalt mixture qualities. Pavement made with different modified bitumen binders is used to aid in resistance to cracking and permanent deformation. Decomposed waste like polyethylene terephthalate (PET) has been successfully used to modify bitumen

... tion. This study assessed the bitumen PET waste's integrity with conventional tests such as penetration, softening point, viscosity, flash and fire point, and ductility tests. Based on the changes in the bitumen results, PET waste proportions of 8%, 10%, and 12% by weight of bitumen content were compared to semi-dense bituminous concrete (SDBC), dense-graded bituminous macadam (DBM), and bituminous macadam (BM). The consistency of bituminous concrete is measured using Marshall values. The PET-modified mixture was found to be more resistant to deformation than the conventional sample, and the rate of deformation in the PET-modified mix was lesser than in the conventional mix.
