“…Yeh et al confirmed the better compatibility of aPP and bitumen as compared to iPPbitumen in the presence of reactive polymers [245]. LDPE and LDPE-g-MA were blended with bitumen and it was observed that LDPE-g-MA showed greater stabilizing effect than LDPE [171]. The rheological behaviour of base bitumen and EVA-g-MA modified bitumen in terms of phase angle and complex shear modulus was investigated by [116].…”

“…A very common content used for polyethylene-based modifiers is 3%, which shows 7% to 42% reduction in penetration, whereas the penetration value is reduced by 22-63% for 5% polyethylene-based modifiers [12]. In relation to the softening point, an increase of 2-50% at 3% polyethylene content and 14-91.5% at 5% polyethylene loading was observed [171].…”

“…It is suggested that the polymer modifiers should be highly compatible to the binder, hence resulting in homogenous blends and minimizing the phase separation during transportation and storage [105]. Different modifiers play different roles in improving the properties of polymer-modified bitumen; for instance, maleic anhydride improves polarity and decreases crystallinity, which disrupts closely packed crystalline microstructure [99] resulting in increased compatibility and storage stability [100,163,171], organic montmorillonite supports chemical bonding between the bitumen and polymer and polyphosphoric acid enhances the rheological characteristics of the binders at high temperatures [194,284]. To date, various modifiers have been employed to obtain the required compatibility and reduce the phase separation during polymer modification of bitumen.…”

The failure of bituminous pavements takes place due to heavy traffic loads and weather-related conditions, such as moisture, temperature, and UV radiation. To overcome or minimize such failures, a great effort has been put in recent years to enhance the material properties of bitumen, ultimately improving field performance and increasing the pavement service life. Polymer modification is considered one of the most suitable and by far the most popular approach. Elastomers, chemically functionalised thermoplastics and plastomers * (* Note: notwithstanding the fact that in Polymer Science the word ‘plastomer’ indicates a polymer with the simultaneous behaviour of an elastomer and plastics (thermoplastics), this paper uses the term ‘plastomer’ to indicate a thermoplastic polymer as it is more commonly found in Civil and Pavement Engineering.) are the most commonly used polymers for bitumen modification. Plastomers provide several advantages and are commonly acknowledged to improve high-temperature stiffness, although some of them are more prone to phase separation and consequent storage instability. Nowadays, due to the recent push for recycling, many road authorities are looking at the use of recycled plastics in roads. Hence, some of the available plastomers—in pellet, flakes, or powder form—are coming from materials recycling facilities rather than chemical companies. This review article describes the details of using plastomers as bitumen modifiers—with a specific focus on recycled plastics—and how these can potentially be used to enhance bitumen performance and the road durability. Chemical modifiers for improving the compatibility between plastomers and bitumen are also addressed in this review. Plastomers, either individual or in combination of two or three polymers, are found to offer great stiffness at high temperature. Different polymers including HDPE, LDPE, LLDPE, MDPE, PP, PS, PET, EMA, and EVA have been successfully employed for bitumen modification. However, each of them has its own merit and demerit as thoroughly discussed in the paper. The recent push in using recycled materials in roads has brought new light to the use of virgin and recycled plastomers for bitumen modification as a low-cost and somehow environmental beneficial solution for roads and pavements.

“…f(α) is a function depending on the conversion ratio and is defined as a special mathematical function that expresses the variation of the conversion ratio with time or temperature. The g(x) function corresponds to the function found by integrating dα/f(α) [41][42][43][44].…”

“…Especially, biocomposite production can be made as a result of the epoxidation of triglyceride structures found in vegetable oils [41]. For example, when palm oil is modified by various processes, a biopolymer can be easily obtained by a chemical reaction [42]. It is known that the synthesized biocomposite, in which palm oil is used in the production of polyester composites, improves some of the thermophysical properties [43].…”

T oday, social awareness of the environmental impacts of plastics is increasing, and therefore environmentally friendly materials are sought for the plastics industry [1][2][3][4]. For this reason, in addition to being environmentally friendly, the tendency towards natural fibers is increasing due to their low cost, easy processing, low density, good corrosion resistance, and high strength in wide industrial applications [5][6][7][8][9][10][11][12][13][14]. Moreover, natural fibers become an alternative to glass fibers by being applied to reinforced polymer composites and natural-based resins, as they contain hydrogen bonds and other bonds that reinforce the structure [15,16]. The use of bio-fibers as substitutes for synthetic fibers (carbon, and glass) as fillers in the development of polymer matrix composites has attracted much attention [17].There is increased awareness about the properties of natural fiber-based epoxy composites to meet engi-Article History:
