“…Furthermore, [20,21] showed that vegetable oil produced from raw materials (rapeseed oil, soybean oil, sunflower oil, linseed oil, canola oil, coconut oil, castor oil, etc.) and mixed in asphalt binder acts as modifiers/additives with different percentages [22]. It is concluded that waste cooking oil (WCO) as rejuvenators is useful for their low cost and fewer environmental concerns.…”

Asphalt is the most commonly used material for pavement construction around the world, and therefore, it is vital to acquaint a practice that restores the reclaimed asphalt pavement (RAP) binder properties to the required level of performance by adding proper rejuvenators. However, a rejuvenator may perform better in the early stages of its application but may not necessarily perform better in the long run. The aim of this study is to assess the rejuvenation effect on the aging resistance of RAP binder in long-life performance through applying artificial aging. In this study, base virgin binder of pen grade 60/70 and RAP binder rejuvenated with Cereclor were subjected to artificial aging to simulate the short- and long-term aging effects. Penetration, softening point, ductility, and viscosity; saturates, aromatics, resins, and asphaltene (SARA) fractionation; and Fourier-transform infrared (FTIR) spectroscopy, bending beam rheometer (BBR), and dynamic shear rheometer (DSR) tests were conducted to evaluate the potential improvements in various properties of RAP binder. The results indicated that the physical, fractional composition, rheological, and aging resistance of RAP binder improved through the rejuvenation mechanism. Therefore, the rejuvenator improved the chemical structure through re-balancing the constituents in the colloidal system, even after long-term re-aging, which proves it to be an aging-resistant binder. Furthermore, it has been concluded that Cereclor has substantial rejuvenation potential even after applying artificial aging, and it can be utilized in pavement recycling to achieve long-life performance. Furthermore, the results depict good correlations between the physical, rheological, and chemical parameters of virgin and RAP binder.

“…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.
