“…Similar results were obtained by Lugeiyamu et al [ 55 ], who analyzed recycled PET. In accordance with the research conducted by Ma and Hesp [ 56 ], the influence of fibers made from processed PET as a modifier in asphalt mixtures was investigated to enhance the crack resistance. It was found that the use of longer and thicker PET fibers with a rough surface in asphalt mixtures at different temperatures can significantly improve their properties.…”

Due to the growing need to recycle plastics, new possibilities for their reuse are intensively sought. In the Asian market, waste polymers are increasingly used to modify road bitumen. This solution is beneficial in many aspects, especially in economic and ecological terms. In this work, recycled poly(ethylene terephthalate) (RPET), obtained from storage points located in Lesser Poland, was subjected to material recycling, and its properties were examined using three analyses: differential scanning calorimetry (DSC), thermogravimetric analysis (TG), and Fourier transform infrared spectroscopy (FTIR). The most important point of this research was the selection of conditions for obtaining modified asphalt mixtures through the addition of RPET. Subsequently, the effect of the polymer on the properties of road bitumens was assessed on the basis of penetration tests, softening point, elastic recovery, and structure. In the last stage of our research work, asphalt mixtures with the addition of modified waste PET (PMA) containing mineral filler in the form of basalt dust were obtained. The properties of the obtained mineral–polymer–asphalt mixtures were compared in terms of frost resistance, structure, and abrasion resistance with the properties of mineral–asphalt mixtures that were taken from damaged road surfaces in four points in the city of Tarnów (Lesser Poland) in the winter of 2022. It has been shown that the modification of road bitumen with the use of recyclate and mineral filler has a significant impact on its performance properties.

“…Another crucial property is the particle size and shape of WPs. Plastic can be added to HMA in many shapes with varied sizes, such as powder (0.035-0.25 mm) [21,22], pellets (5-10 mm) [23], fibers (6.5-30 mm) [24][25][26], flakes (0.63-10 mm) [27][28][29][30], or granules (0.3-0.6 mm) [31,32]. WPs can also go through some processes for size reduction, such as shredding, grinding, crushing, and cutting [10,[33][34][35].…”

Although waste plastic (WP) application as a paving material has drawn increasing attention from scholars, there is a lack of studies that summarize the latest development of WP research. Considering there is no standard procedure to incorporate WPs in asphalt mixtures, it is important to document the major findings from the available literature to identify knowledge gaps to tackle in future research and advance knowledge on this subject. Using a bibliometric analysis method, this study carries out a holistic review of WP articles published from 2003 to 2023, focusing on incorporating WP in asphalt mixtures via the dry method. This study particularly focused on identifying and evaluating individual types of WP mostly used in asphalt mixtures via the dry method and how their most common characteristics (size, shape, and melting point) affect the mixing procedure and the overall mixture’s performance. The analysis highlighted China, the USA, and India as leading countries in WP-related publications. Typically, low-density polyethylene (LDPE), high-density polyethylene (HDPE), and polyethylene terephthalate (PET) were the most utilized WPs in the dry method. Smaller WP particle sizes (<2.36 mm) were considered more suitable in asphalt mixtures. In general, studies employing procedures involving WP melting, typically by introducing WP to pre-heated aggregates at temperatures surpassing its melting point, resulted in improved asphalt mixtures with enhanced resistance to rutting, cracking, and moisture damage. In this context, positive performance outcomes were notably observed in studies using HDPE or LDPE, potentially because of their low melting point. The key knowledge gaps identified were the lack of a consistent procedure applicable across studies, a feasibility assessment for scaling laboratory-based procedures to field applications, and laboratory evaluations utilizing advanced performance tests as suggested in the Balance Mix Design (BMD) approaches.

“…The use of thicker, longer PET fibers with a rough surface has been seen to improve the hardness of asphalt mixes at various temperatures [14]. Utilizing the findings of the dynamic shear rheometer, the performance of modified asphalt paving was modeled by adding PET using AASHTO Ware Pavement ME Design software [15].…”

Climatic conditions, escalating traffic loads, and inadequate maintenance have been identified as significant contributors to the degradation of road quality, resulting in suboptimal performance of paved roads. One of the critical forms of deterioration is the premature hardening of asphalt, which leads to early onset of cracks and, consequently, the premature failure of pavement surfaces. In response to these challenges, this study explores an innovative approach to improve the properties of asphalt mixes by integrating plastic waste, thus prolonging pavement service life, reducing construction and maintenance costs, and mitigating environmental pollution. Specifically, waste Polyethylene Terephthalate (PET), derived from plastic water bottles, was incorporated as a polymer additive in asphalt mixtures. Asphalt specimens, both modified and unmodified, were produced by integrating plastic waste in proportions of 0, 3, 6, 9, and 12 percent by the weight of asphalt. The specimens were evaluated for their Marshall Stability, flow, and volumetric properties using digital Marshall testing equipment on a selected size range (2.36-1.18 mm) employing a dry process. All test results conformed to Iraqi standard specifications, highlighting an enhancement in the mix properties compared to the conventional mixture. The augmentation of plastic waste was consistent with previous findings and demonstrated improved engineering features of the mixtures. The ideal proportion of waste plastic water bottle integration was found to be 7.77%, resulting in an increase in stiffness and stability by 70.45% and 42.10%, respectively, compared to a conventional mix.
