“…The reclaimed cooking oil (WCO) is conducive to the physical properties, rheological properties, and other pavement behaviors of asphalt binders [10][11][12]. Eleyedath et al [13] believed that the light components contained in such regenerating agents had a small molecular weight and low viscosity, which could quickly restore their performance after mixing with the aged asphalt; however, the difference in molecular weight between these lightweight components and other molecules was too large, which led to poor compatibility, and the rapid loss of small and medium molecules caused the poor durability of asphalt pavement. The use of bio-oil can improve the low-temperature cracking resistance of aged asphalt, and its microstructure is similar to that of base asphalt [14][15][16].…”

The single light oil regenerating agent has certain limitations on the performance recovery of aged asphalt. In this study, tung oil, dioctyl phthalate (DOP), C9 petroleum resin, and organic montmorillonite (OMMT) were used to prepare the composite regenerating agent, and its optimal mix proportion was determined by the orthogonal experimental design. The rheological properties and anti-aging performance of reclaimed asphalt were studied by the dynamic shear rheometer (DSR) and bending beam rheometer (BBR); and the Fourier transform infrared (FTIR) spectrometer, gel permeation chromatography (GPC), and scanning electron microscope (SEM) were adopted to explore its microstructure, morphology, and mechanism of action. The results show that with the addition of tung oil composite regenerating agent, the rheological properties of aged asphalt can be effectively recovered, even better than that of base asphalt. By using the complex modulus aging index (CMAI) and phase angle aging index (PMAI) it is found that the anti-aging performance of reclaimed asphalt is better than that of base asphalt. With the optimal content of the tung oil composite regenerating agent, the contents of characteristic functional groups and macromolecular asphaltenes in the aged asphalt can be reduced, indicating that the composite regenerating agent is beneficial to the dispersion and dissolution of polar substances in the aged asphalt. After aging, a large number of wrinkles appear on the surface of the asphalt. However, the addition of the tung oil composite regenerating agent can make the asphalt surface smooth, which indicates that the tung oil composite regenerating agent can restore the microstructure and morphology of aged asphalt to a certain extent.

“…Waste engine oil disposal and reuse is a major challenge worldwide as a large amount of waste engine oil is generated from various industries, such as automotive [1,2]. One possible way is the use of the oil as additives or structure modifiers in combination with bitumen materials [3,4]. Used automotive oil is an industrial waste with the potential to be recycled into alternative constituents, such as additives to enhance bitumen emulsion properties.…”

Emulsified bitumen is an aqueous mixture of bitumen and can be used in insulation and coating applications. In this study, used automotive oil was utilized as a component in bitumen emulsion formulation. Five formulations of bitumen emulsion comprising different ratios of neat bitumen and recycled automotive oil were formulated, namely EMB01–EMB05. The formulation utilized 1 g of abietic acid (C20H30O2) as an emulsifier. The formulated bitumen was characterized for penetration, softening point, differential scanning calorimetry, viscosity, and oscillatory test, and the results were compared to commercial bitumen emulsion (ATLAS bitumen emulsion). The results show that EMB05 has softer consistency, high viscosity, temperature susceptibility, higher thermal stability, and an adaptable viscoelastic range compared to other formulations that provide suitable properties for coating and insulation of wall waterproof material.

“…However, the presence of volatile components in REO can compromise its thermal stability, and its incorporation tends to diminish the high-temperature performance of modified asphalt (Wang W. et al, 2020;Liu et al, 2022a). As the addition of REO increases, so too do its adverse effects (Eleyedath et al, 2020;Liu et al, 2022b).…”

During the preparation of asphalt mixtures, styrene-butadiene rubber (SBR) polymers are susceptible to thermal decomposition, which can significantly impair the binder’s low-temperature performance. This study explores the potential of combining warming agents with waste materials to enhance the low-temperature properties and aging resistance of the binder. Specifically, it examines the synergistic impact of Sasobit/recycled engine oil (Sasobit/REO) composites on the rheological and physical attributes of styrene-butadiene rubber asphalt binder (SBRAB). Utilizing fluorescence microscopy (FM), bending beam rheometer (BBR), and dynamic shear rheometer (DSR), the study assesses the aging resistance and modification mechanisms of Sasobit/REO on SBRAB. The findings indicate that the incorporation of Sasobit/REO composites more effectively reduces the mix preparation temperature than either component alone. The preparation of Sasobit/REO warm mix asphalt mixtures is feasible at temperatures 20°C lower than those required for traditional hot mixtures. These composites also enhance the performance of SBRAB at both high and low temperatures, counteracting the adverse effects associated with the individual use of Sasobit or REO. This reduced short-term aging temperature is beneficial in lessening the negative impact of high temperatures on SBRAB’s performance. Moreover, the addition of Sasobit/REO composites significantly improves the thermal cracking resistance of SBRAB mixtures. The study also demonstrates that Sasobit/REO enhances the short-term and long-term aging resistance of SBRAB, paving the way for the broader application of this novel warm mix additive in the asphalt industry.
