“…Te penetration and ductility of the bitumen modifed with recycled plastic polymer chips decrease as the content of the plastic additives increases. Tis contributes to the expected substantial increase in life of pavement surfacing in comparison to using ordinary bitumen [31][32][33][34][35][36][37].…”

Nowadays, the use of recycled waste materials in road pavement is regarded not only as a positive option in terms of sustainability but also as an appealing option in terms of providing improved service performance. The current study aimed at evaluating the performance of crumb rubber and polyethylene terephthalate plastic polymer in asphalt mixture in modifying the mechanical properties of asphalt pavement. Experimental tests were carried out both for asphalt binder and asphalt mixture. Different proportions of mix for crumb rubber and polyethylene terephthalate plastic polymer were used to systematically investigate the effect of mix ratio on performance of the asphalt material. The experimental analysis reveals that the combined application of 10% by weight of crumb rubber chips and 2% polyethylene terephthalate plastic polymer are the ideal mix ratios found effective in modifying properties of the asphalt mixture. The asphalt binder test results indicate that adding 10% crumb rubber to asphalt binder reduced penetration by 1.56% along with increment of the softening point by 4.33%. Furthermore, the indicated optimum mix amount resulted in 0.17% rise, 20.07% drop, and 20.71% increase in Marshal stability, flow, and stiffness, respectively. Besides, tensile strength of the asphalt mixture was enhanced with addition of the filler and binder materials. It was witnessed that the combined application of the additives performs better than their separate use in modifying properties of the asphalt mix.

“…Gopinath & Kumar [19] used modifiers to improve the rheological behaviour of bitumen, and they concluded that Polymer (PET)-modified bituminous binders offered better resistance against permanent deformations due to their higher phase angle and a higher softening point when compared to conventional binders. In the experimental study of Ogundipe [20], PET waste was used as a modifier for asphalt concrete, and he obtained a significantly reduced stability of 20.4% in PET modified asphalt concrete and improved permanent deformation resistance of the PET modified asphalt compared to unmodified asphalt concrete. This is a good pointer that PETmodified bitumen could be used in paving applications.…”

This study considers the utilization of bitumen modified with molten polyethylene terephthalate (PET) waste bottles as an alternative binder in paving blocks. PET waste was used at 2, 4, 6, 8, and 10% to modify bitumen in the production of paving blocks. Compressive strength test and skid resistance test were conducted on the paving block samples to evaluate their mechanical strength properties, while water absorption and the Cantabro abrasion tests were carried out to ascertain the durability of the paving block samples. The PET-modified bitumen paving blocks (PMBPB) have enhanced compressive strength and skid resistance compared to unmodified bitumen paving blocks. Also, a significant reduction in water absorption rate of up to 56% was achieved in PET-modified bitumen paving blocks (PMBPB) compared to the unmodified sample. The abrasion loss in the PMBCB samples was the least compared to that in normal cement paving blocks and unmodified bitumen paving blocks. The maximum compressive strength and least water absorption for the PET-modified bitumen concrete paving blocks were obtained at a 10% PET replacement level. It can be concluded that enhanced compressive strength and durability in cement paving blocks and unmodified bitumen paving blocks could be achieved with the use of PET modified bitumen in concrete paving block production, and this will also encourage PET waste recycling and contribute meaningfully to sustainability in concrete paving block production.

“…In *Corresponding author: christian.geralddaniel@gmail.com particular, PE can also be combined with aramid fibre to enhance the mechanical properties of bituminous mixes regarding their strength, fatigue life, stiffness, and resistance to rutting at various temperatures by mainly acting as bonding enhancement and a load-carrying agent inside the asphalt matrix [20][21][22][23][24][25][26][27]. Meanwhile, PET is typically used in the form of plastic waste products to either modify binder stiffness or act as an additive in a mixture, both of which were found to increase the resistance to rutting and moisture damage, as well as higher strength and fatigue life of a bituminous mixture [28][29][30][31][32][33]. There is also a plant-based type of fibre, such as cellulose fibre.…”

This research aims to observe the effect of applying cellulose fibre to the mechanical properties of bituminous mixtures when subjected to various loading speeds that simulate various traffic situations with fibre dosages of 0.3 – 0.5% of mix weight. The semi-circular bending (SCB) test was employed in this project, where the specimens were subjected to loading speeds of 0.25, 0.5, and 1 mm/min. The incorporation of cellulose was reported to enhance the tensile strength of the specimens up to 43.75% at the lowest loading rate and 13.75% at the highest rate, while the critical strain energy was elevated to 24.54% at the lowest rate and 38.2% at the highest rate, signifying better resistance against loading. Meanwhile, the flexibility index (FI) of modified specimens showed a mixed trend compared to the control mix, 30.43% higher at the lowest rate and 28.9% lower at the highest rate. To sum up, the incorporation of cellulose fibre into the bituminous mixture can enhance its strength and resistance against various loading rates, and the fibre dosage of 0.3% is recommended to give the best outcome.
