“…Similarly, fluorescent images have been used for the investigation of the thermal stability of SBS-modified asphalt. Islam et al [ 177 ] conducted a thorough investigation into the thermal deterioration of the SBS-modified binder. The authors utilized 3, 4.5, and 7 % by weight of bitumen and evaluated the SBS-MB morphology concerning SBS concentration.…”

“…Islam et al found that when SBS content exceeds 3% by weight, the subsequent creation of an interconnected maltene-polymer-rich network significantly improves the properties of SBS-MBs. Even a modest modification to the polymer network in the steep intermediate zone (3 to 6% by weight) can dramatically alter the properties of SBS-MBs [29].…”

Polymer modified asphalt (PMA) mixtures are commonly employed in flexible pavement and overlays with large traffic volumes. In contrast, a number of laboratory and field tests have been conducted to evaluate the performance of PMA with that of conventional hot mix asphalt (HMA) mixtures. This paper presents an overview of the various polymers utilised in asphalt mixtures and their effects on the rheological, morphological, physical, and mechanical properties of polymer-modified asphalt binders. According to a review of the relevant literature, a good modifier affects the failure characteristics of the binder, allowing it to withstand greater stresses and strains before failing. In asphalt pavement, adding polymers to asphalt binders to improve their qualities has a long history. Due to polymers' limited solubility, polymer-modified asphalt binders may have several disadvantages. In addition, a brief description of the general approach to mixing polymers is provided. A summary of the benefits and drawbacks of the most common polymers used to alter asphalt binders Styrene-butadiene-styrene (SBS), Styrene-butadiene–rubber (SBR), Polyethylene Terephthalate (PET), Polypropylene (PP), Polyvinyl Chloride(PVC) etc. are illusrated. The paper continues with a discussion of the lasting effects of PMAs on asphalt pavement. To evaluate the economic and environmental impacts, a life cycle assessment (LCA) is required.

“…For instance, Ali Behnood et al [19] found that polymer-modified asphalt is 1.5 times costlier than traditional asphalt, leading to a 20% increase in the cost of the modified mixtures. SK Sohel Islam et al [20] have observed that the degradation of SBS at high temperatures significantly reduces the Marshall stability, indirect tensile strength, fatigue, and rutting resistance of asphalt mixtures regardless of the grade and source of the base asphalt. Xiong et al [21] noted that achieving a high performance in SBS-modified asphalt not only requires chemical adjustments to restore its properties but also the reconstruction of the polymer network through the chemical structure of products from SBS degradation products.…”

This study comprehensively examines the influence of phenol-formaldehyde resin (PF) on the performance of base asphalt and its mixtures for road applications, emphasizing its innovative use in enhancing pavement quality. Optimal PF content was determined through the evaluation of standard indicators and rotational viscosity. In-depth analyses of PF-modified asphalt’s high- and low-temperature rheological properties and viscoelastic behavior were conducted using dynamic shear rheometers and bending beam rheometers. Aging resistance was assessed through short-term aging and performance grade (PG) grading. Moreover, Marshall and water stability tests were performed on PF-modified asphalt mixtures. Findings indicate that the uniform dispersion of PF particles effectively inhibits asphalt flow at high temperatures, impedes oxygen penetration, and delays the transition from elasticity to viscosity. These unique properties enhance the high-temperature stability, rutting resistance, and aging resistance of PF-modified asphalt. However, under extremely low temperatures, PF’s brittleness may impact asphalt flexibility. Nonetheless, the structural advantages of PF-modified asphalt, such as improved mixture density and stability, contribute to enhanced high-temperature performance, water stability, adhesion, and freeze–thaw cycle stability. This research demonstrates the feasibility and effectiveness of using PF to enhance the overall performance of base asphalt and asphalt mixtures for road construction.
