“…The x‐ray diffraction pattern of GO, D‐GO, and DH‐GO were shown in Figure 1d. Figure 1d indicated that the characteristic diffraction peak of GO was located at 2 θ = 11.7°, which was consistent with relevant reports 31 . For D‐GO, the sharp diffraction peak of GO became weaker.…”

A composite graphene oxide (GO) modifier was prepared by co‐deposition of polydopamine (PDA) and hexadecyltrimethoxysilane (HDTMS) with hydrophobic function to enhance the interfacial interaction between GO and asphalt. Dopamine as a medium enhances the adhesion of the hydrophobic functional material HDTMS on the surface of GO. And the long alkyl chains of HDTMS molecules greatly reduce the surface free energy and ensure the dispersion stability of composite GO modifier in styrene–butadiene–styrene (SBS) modified asphalt. The physical properties of modified asphalt show that the ductility, high‐temperature stability, and viscosity of asphalt can be improved by the addition of PDA/HDTMS composite GO modifiers (DH‐GO). Among them, 0.04% DH‐GO composite SBS modified asphalt binder (DH‐GO/SBSMB) has the best mechanical properties. Compared with 0.05% GO composite SBS modified asphalt binder (GO/SBSMB), the softening point of 0.04% DH‐GO/SBSMB increased by 8.3%, the penetration degree decreased by 9.7%, and the elongation increased by 18.2%. Dynamic shear rheometer (DSR), multiple stress creep recovery (MSCR) and rotational viscosity (RV) tests show that 0.04% DH‐GO/SBSMB has higher high‐temperature stability, plasticity, and viscosity than 0.05%GO/SBSMB, which meets the requirements of asphalt construction specifications.

“…This allows the asphalt to better resist cracking, rutting, and other forms of distress, which can prolong the life of the pavement. Additionally, SBS also improves the adhesive properties of the asphalt and viscosity consequently, allowing it to better bind to aggregates and form a stronger and more durable road surface [ 11 ].…”

The study presents an experimental evaluation to improve the resistivity of binders with “Styrene-Butadiene-Styrene” (SBS) and “Processed oil” by studying the physical properties, rheology, and cracking. For this experiment, PG 64-22 was mixed with SBS at different percentages of 5%, 10%, and 15% by weight of the original binder with two processed oil contents of 6% and 12% by weight of the binder. Laboratory tests have been conducted at various high, medium, and low temperature ranges to evaluate their properties. The processed oil polymer modified asphalt (PMA) binder is artificially aged in both the short and long-term using a Rolling Thin Film Oven (RTFO) and a Pressure Aging Vessel (PAV). The Superpave testing method was performed on modified binders using a Rotational Viscometer (RV), Dynamic Shear Rheometer (DSR), and Bending Beam Rheometer (BBR). The results of this study illustrate (1) The addition of SBS leads to higher viscosity, but the co-modification of asphalt binder with the processed oil shows a significant modulation of the viscosity value. (2) In addition, processed oil reduced the resistance to rutting, but the addition of SBS significantly improved the rutting resistance of the asphalt binder. (3) The addition of SBS and processed oil improved the value of G sin δ, notably. (4) According to BBR, it has been shown that the addition of SBS in addition to the processed oil improves the stiffness values of modified asphalt binders.

The unavoidable aging of road pavements due to years of exposure to heavy traffic volume and climatic and environmental changes finally results in a decrease in the performance of the asphalt binder and the performance of the pavement. One of the major causes of road failures is due to poor performance of bitumen pavements and their maintenance. Rutting during hot summer and cracking during winter are the most common problems in the performance of bituminous roads (50 mm or thicker). In the present study, chitosan which is a crustacean waste, and nitrile butadiene rubber (NBR) which is a shoe sole waste are used as reinforcement materials in bitumen. Basic engineering tests rolling thin film test (RTFO), pressure aging vessel (PAV), etc., were performed on the bitumen composite to understand the impact of additives on bitumen's physical characteristics. Advanced characterization methods, including X-Ray Diffractometer (XRD), Scanning electron microscopy (SEM-EDAX), Raman Spectroscopy, Dynamic Shear Rheometer (DSR), Multiple stress Creep recovery (MSCR) were employed to examine the structural, morphological, compositional, and performance characteristics of bitumen.
