The objective of this research is to investigate the physiochemical and rheological properties of waste cooking oil (WCO)/styrene‐b‐butadiene‐b‐styrene/ethylene vinyl acetate (SBS/EVA) composite modified asphalt. A petroleum asphalt composite modified with SBS/EVA and oil/SBS/EVA were prepared to undergo the physical, rheological, and microscopic experiments. Comparing these tests results with the properties of unmodified petroleum asphalt, SBS and EVA cause an improvement in pavement performance, but weaken the storage stability. Although the high‐temperature performance undermined by the addition of WCO, the thermal stability, fatigue property, and low temperature crack resistance improved obviously. In addition, WCO mainly composed by low‐weight components, and these can supplement the light components in the polymer‐modified asphalt. EVA could increase the percentage of large molecular size of asphalt, while WCO relieves this trend. The reactions between WCO and these polymers (SBS and EVA) are physical reactions. Atomic force microscopy morphology results reflect that SBS and EVA increase the surface complexity and roughness, and WCO makes the asphalt surface smooth. This indicates WCO increases the dispersion of polymers in asphalt. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48828.

“…Based on the previous researches, the mass content of WEO or WPE in asphalts is usually within 10 wt % [32][33][34]. Therefore, the asphalt samples containing 2, 4, 6 and 8 wt % of WEO are abbreviated to 2%WEO, 4%WEO, 6%WEO, and 8%WEO.…”

Waste engine oil (WEO) and waste polyethylene (WPE) are two common wastes, which are easy to pollute the environment. As the primary material in road construction, natural asphalt is a non-renewable energy source and asphalt is vulnerable to ultraviolet (UV) radiation during the service life. It results in degradation of asphalt pavement performance. In this paper, 2 wt % to 8 wt % of WEO and WPE were used to modify asphalts and the UV aging simulation experiment was carried out. The physical parameters of asphalts before the UV aging experiment show that the asphalt containing 4 wt % WPE and 6 wt % WEO mixture (4 wt % WPE + 6 wt % WEO) has similar physical properties with that of the matrix asphalt. Besides, gel permeation chromatography (GPC) verifies that the molecular weight distribution of the asphalt containing 4 wt % WPE + 6 wt % WEO is close to that of the matrix asphalt. The storage stability test shows that 4 wt % WPE + 6 wt % WEO has good compatibility with the matrix asphalt. The functional groups and micro-morphology of asphalts before and after the UV aging experiment were investigated by Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). FTIR results display that 4 wt % WPE + 6 wt % WEO can effectively reduce the formation of carbonyl and sulfoxide functional groups. AFM shows that 4 wt % WPE + 6 wt % WEO can also retard the formation of a "bee-like" structure in asphalt after the UV aging experiment. Based on the above results, it can be concluded that WEO and WPE mixture can replace part of asphalt and improve the UV aging resistance of asphalt.

“…To improve the properties of asphalt binder's to achieve a higher resistance against pavement distress; various researchers have considered the modification of asphalt binders with crumb rubber tyre, used engine oil, carbon black, waste water sachet, styrene-butadiene-styrene, and other materials (Vila-Cortavitarte et al, 2018;Baqersad et al, 2019;Liu et al, 2019;Jahangiri et al, 2019;Wei et al, 2019;Pouranian and Shishehbor, 2020;Notani et al, 2020;Afolayan et al, 2021). Considering few researches in the areas of volumetric and moisture susceptibility of UTI in asphalt modification, this study focused on the analysis and investigation of the suitability of UTI on the volumetric properties of asphalt mix, with the sole objective of identifying the properties of asphalt mix modified with used toner and the evaluation of the effect of UTI on the stability.…”

The research centered on the effect of used toner ink (UTI) as bitumen modifier in asphalt mix as paving materials with respect to the volumetric properties and durability. In this research, UTI are proportioned into the asphalt binder for mixing the asphalt concrete in percentages of 2%, 4%, 6%, 8% and 10%. Marshall and Cantabro loss tests were carried out on the hot asphalt mix. All the percentage proportion of used toner added was evaluated with the following parameters: voids in the mineral aggregates (VMA), voids in total mix (VTM), voids filled with asphalt (VFA), Marshall stability, flow value, and specific gravity. It was observed that asphalt mix with UTI performed better under loading as the UTI in the asphalt mix increases. The highest Marshall stability was observed to be 32,352N at 6% UTI, also there is reduction in the optimum bitumen content as the UTI, which helps in reducing the amount of bitumen needed in the course of asphalt pavement construction. In respect of this research further asphalt pavement design can be modified to provide pavement that can be more sustainable and durable over a long period of time, thereby reducing the cost of asphalt mix production.
