“…As mentioned before, as PET is a thermoplastic material that stiffens the bitumen more than the rubber part, an increase of up to 50% PET and 50% CR in the PET/CR ratio increased the mixtures' resilient modulus, but higher PET percentages reduced it (also mentioned in [30][31][32][33][34][35]). Previous studies confirmed that the addition of PET/CR improved this modulus [31][32][33][34][35] and stated that an increase in CR in the PET/CR ratio declined the additive distribution in the bitumen matrix due to, maybe, the CR partial cross-linking and low thermoplastic PET swelling [54]. is might be due to the formation of a continuous elastic network and rubber powder as an elastic component compensates the undesirable (stiffening) effects of PET as the plastic constituent resulting in improved functional properties of binders at intermediate temperatures.…”

This research intends to evaluate the effects of the waste polyethylene terephthalate (PET), antistripping agents (ASA), and ground tire rubber (GTR) on the performance properties of the stone matrix asphalt (SMA) mix binder/water damage resistance. Liquid antistripping agents, added to 85/100 penetration grade binder to evaluate the ASA effects, were A (M500), B (EvothermM1), and C (LOF-6500). Tests conducted to study the modified bitumen’s rheological properties included softening point, penetration, rotational viscosity (RV), and dynamic shear rheometer (DSR), and tests performed in order to examine the moisture sensitivity of the modified mix were the Texas boiling and resilient modulus (MR), fracture energy (FE), and indirect tensile strength (ITS) ratio tests. Results showed that the MR, ITS, and FE of asphalt mixes modified with crumb rubber (CR), ASA, and PET were improved. Adding 50% PET, 50% CR, and ASA (B) led to the highest tensile strength, resilient modulus, and fracture energy ratios showing a perfect water susceptibility of the mentioned mix.

“…[105] Better performance in various measurements was found when the terminal groups were amines instead of hydroxyls in BHETA indicating that the identity of the terminal groups are important likely because of the more facile reactivity of amines. [106] A similar approach, except in this case using glycolysis via propylene glycol, was used as well. In this case, the reaction was complete in one case and only 50% complete in the other.…”

Among possible applications for post-consumer waste plastics, one criterion is that the application should be able to use very large amounts of material because the amount of plastic waste is so large. Another key issue is economics; very little cost should be involved in preparing waste plastics for a specific application. One of the few applications for post-consumer waste plastics that could possibly meet both requirements is filler in asphalt concrete. Specifically, if waste plastics in asphalt concrete were 10 wt%, then this application alone could use all plastic waste currently being produced in the world. This review examines the progress that has been made to incorporate waste plastics into asphalt concrete and identifies key issues preventing this technology from being applied commercially.

“…This section investigates the differences in the mechanical properties (e.g., fatigue damage, rutting deformation, and moisture sensitivity) of asphalt mixtures as a result of adding recycled PET waste. These properties are derived from the results of past investigations [38,45,49]. In previous studies, PET waste material was mostly applied to asphalt mixtures using the dry process [34] or used as a replacement to the fine aggregates in the mixture to enhance pavement resistance to permanent deformation [50].…”

“…The micronized PET had the least impact on moisture damage in asphalt mixtures, likely because the PET particles improved the mastic cohesion, via binder rheology, mechanical adhesion, and surface energy. On the other hand, Padhan et al [49] evaluated the stripping resistance of an asphalt mixture using amine-based additives. The results showed that BAET significantly improved the resistance of the asphalt mixtures against These findings agree with those of Ameri and Nasr [48], who showed that PET additive improved asphalt mixture resistance against moisture as seen in Figure 15, but the improvement decreased when a higher amount of PET was added, resulting in reduced asphalt binder workability.…”

A Brief Review: Application of Recycled Polyethylene Terephthalate in Asphalt Pavement Reinforcement

Plastic is considered one of the most significant industrial inventions of this era due to its excellent properties, which lend well to many manufacturing applications. These days, there are tons of Polyethylene Terephthalate (PET) waste products that are generated around the world. This waste presents a real environmental hazard because PET is not biodegradable. This paper delineates the physical and chemical properties of PET to justify its use as an additive and aggregate replacement in the manufacture of asphalt mixtures. Furthermore, discusses details of PET-modified asphalt mixture by a dry and wet process with sufficient information to better understand the mixture. Several critical matters are investigated, such as asphalt modification to increase resistance to fatigue, rutting deformation, and moisture sensitivity. These results are important for determining the factors that significantly improve pavement mixture characteristics. The findings show that the addition of PET to asphalt mixtures yielded very promising results. PET enhanced the mechanical properties, the durability, and the long-term sustainability of the pavement. Finally, using PET waste as an additive in asphalt mixtures could serve as an environmentally friendly method to dispose of PET waste while simultaneously producing high-quality pavements.
