“…of VCO into bitumen improved its rheological properties, reversing the stiffening of short-term aged (STA) and long-term aged (LTA) bitumen compared to a commercial rejuvenator. Similarly, Tarar et al [ 30 ] evidenced a reduction in |G*| when VCO was added in a content of 5% wt. of bitumen, improving its fatigue performance.…”

“…Regarding the use of rejuvenators, the National Center for Asphalt Technology (NCAT) [ 27 ] and the Belgian Road Research Centre (BRRC) [ 28 ] includes a common category of rejuvenator coming from vegetable sources including triglycerides and fatty acids and vegetable oil from agroindustry, respectively. Based on this, several studies [ 19 , 29 , 30 ] have proposed the sunflower oil (named virgin cooking oil—VCO in this study) as a promising rejuvenator with softening effect for long-term aged (LTA) bitumen. The work of Shirzad et al [ 29 ] found that adding 5% wt.…”

This study aimed to determine an optimal dosage of sunflower oil (i.e., Virgin Cooking Oil, VCO) as a rejuvenator for asphalt self-healing purposes, evaluating its effect on the chemical (carbonyl, and sulfoxide functional groups), physical (penetration, softening point, and viscosity), and rheological (dynamic shear modulus, and phase angle) properties of long-term aged (LTA) bitumen. Five concentrations of sunflower oil (VCO) were used: 1%, 2%, 3%, 4%, and 5% vol. of LTA bitumen. VCO was encapsulated in alginate biopolymer under vibrating jet technology using three biopolymer:oil (B:O) mass ratios: 1:1, 1:5, and 1:9. The physical, thermal, and mechanical properties of the capsules were studied, as well as their effect on the physical properties of dense asphalt mixtures. The main results showed that an optimal VCO content of 4% vol. restored the chemical, physical, and rheological properties of LTA bitumen to a short-term ageing (STA) level. VCO capsules with B:O ratios of 1:5 presented good thermal and mechanical stability, with high encapsulation efficiency. Depending on the B:O ratio, the VCO capsule dosage to rejuvenate LTA bitumen and asphalt mixtures varied between 5.03–15.3% wt. and 0.24–0.74% wt., respectively. Finally, the capsule morphology significantly influenced the bulk density of the asphalt mixtures.

“…On one hand, the use of plant oil in composite bitumen modification can supplement light components and adjust the composition of bitumen, similar to its functioning in neat bitumen or aged bitumen (Gökalp and Uz, 2019;Joni et al, 2020;Tarar et al, 2020;Lv et al, 2021;Ma et al, 2021). Additionally, plant oil can activate other modifiers, enhancing the performance and compatibility of modified bitumen (Aldagari et al, 2021).…”

“…Additionally, sunflower seed oil (SO) can serve as an antiageing modifier in asphalt binders. Tarar et al reported that the addition of sunflower seed oil can enhance the fatigue resistance and ageing durability of asphalt binders (Tarar et al, 2020). The presence of α-tocopherol in sunflower seed oil is believed to undergo carboxylic acid and bitumen anhydride esterification.…”

Non-renewable nature and continuously increased consumptions of bitumen is a serious challenge for the development of infrastructure, especially for the constructions and maintenances of asphalt pavements. To cope with this situation, some sustainable strategies are needed. Extensive efforts have been made to improve the resilience, sustainability and circularity of asphalt pavements. Among them, the utilisation of bio-based materials is one of the most promising measures. This paper systemically reviewed the state-of-the-art knowledge in the development of bio-bitumen. Wood-based oils, waste cooking oils and manure-based bio-bitumen were selected as the review objectives. It was revealed that all bio-based oils currently being used are more suitable for serving as additives like softeners, rejuvenators, or modifiers rather than as alternative of binders. One of the most promising utilisations of bio-oils is as rejuvenators, potentially antioxidants as well. Incorporating polymers with bio-oils is another feasible practice to improve the performance of bio-bitumen. Causation should be taken when producing bio-based bitumen since compatibility might have some kind of influence on the performance and this issue should be addressed carefully.

Characterization of Asphalt Aging by Analytical Techniques: A Review on Progress and Perspectives

This review describes the chemical composition of asphalt, which is relevant for the development of materials with higher quality and durability. Asphalt aging can occur in the short term (during machining and storage periods) and the long-term (during the time the pavement is exposed to the environment). To understand the effect of aging on the chemical and physical properties of asphalt, we reviewed the short-term (rolling-thin film oven test (RTFOT) and its variations) and long-term (pressure aging vessel (PAV) and its variations) aging methods and the effects of the sun’s ultraviolet radiation (Suntest and its variations). We also explored the main chemical reactions that occur in the aging processes, such as oxidation, polymerization, and aromatization. For a more accurate assessment of the classes of compounds that undergo aging reactions, fractionation techniques have been developed over the years, such as separation of asphalt into saturates, naphthenic-aromatics, resins, asphaltenes, organic sulfides, nitrogenates, and oxygenates, among others. Despite several studies on the theme of asphalt aging, it is still necessary to understand the phenomena that occur in those processes.
