“…A little amount of castor oil improved the visco-elastic and physical properties of asphalt binders with respect to viscosity, penetration index, and softening point, among other parameters. Nonetheless, larger quantities of castor oil influenced the rheological and physical properties of binders negatively, while atomic force microscopy additionally revealed an improvement in the binders' susceptibility to thermal and rheological variations (Nayak and Sahoo, 2017;Zeng et al, 2016). Canola oil was also utilized as a modifier for bitumen.…”

“…The results showed that at a 5% bio-oil addition level, the rutting and fatigue resistances were more desirable compared to natural binders. Nonetheless, it was emphasized that the results can only be confirmed sequel to mix performance assessments (Nayak and Sahoo, 2017). Bio-oils from soap stock was incorporated improve the adhesion property of biobinders obtained from vegetable oils.…”

“…One of the critical problems that results in pavement distress and reduced serviceability is the asphalt ageing (Mturi et al, 2014;Nayak and Sahoo, 2017). The high level of dissimilarity in the composition of different waste materials in terms of morphology, rheology, and physicochemical characteristics, have resulted in massive variations in the performance and resistivity to thermal and oxidative ageing (Kakar et al, 2015;Som e et al, 2016).…”

The rate at which the construction industry explores and consumes non-renewable natural aggregates and other industrial products such as bitumen, lime, and cement during construction and rehabilitation of road pavements has over time proven to be environmentally degrading and non-sustainable. This, alongside the issues of high solid waste generation and inadequate disposal, has led to series of studies by various researchers to find methods to integrate these solid wastes as alternative materials in road construction and maintenance. This paper provides a simple yet detailed review of recent relevant studies conducted to understand the alarming rate of generation and the effects of reusing these waste materials in both flexible and rigid pavements. The review further outlines the advantages and disadvantages of the selected waste materials and compare the results with that of conventional materials in accordance with relevant standards while highlighting the performance, and life cycle environmental and economic sustainability implications. The study shows that the adoption of these materials offers efficiency in waste disposal while reducing the demand for natural aggregates and consequently, significantly reducing life cycle impacts and costs. The challenges limiting the effective practical implementation of these waste recycling techniques in the construction industry were discussed and possible solutions were suggested to encourage and ensure its utilization in road construction.

“…However, the fatigue factor cannot characterize the fatigue damage characteristics, and it has poor correlation with the asphalt mixture's fatigue property. Asphalt fatigue life, which is obtained from the time sweep test, can reflect the fatigue resistance of the corresponding asphalt mixture [23]. The number of loading cycles (N f50 ) in the case of a complex modulus decreased to 50% is taken as the index for judging the asphalt fatigue [16].…”

In order to guarantee the service performance of recycling asphalt mixture with reclaimed asphalt pavement (RAP), asphalt rejuvenator shall be added. In the last five years, vegetable oil-based rejuvenators have received more and more attention due to their green and regenerative advantages. The object of this paper is to investigate the feasibility of rejuvenating aged asphalt by a kind of waste vegetable oil (W-oil). The effect of W-oil on the performance of aged asphalt is characterized by a safety property test, aging property test, and pavement performance tests; the pavement performance tests included traditional tests and a rheological test. The results show that both the safety property and aging property of rejuvenated asphalt with W-oil meet the specification requirements. According to the results of traditional performance indexes (i.e., penetration, soften point, and ductility), the pavement performance of rejuvenated asphalt can be recovered to the level of virgin asphalt. According to the results of performance indices obtained from the rheological test, the optimum dosage of W-oil is determined to be 13.4 wt %. Compared with virgin asphalt, the rutting property of rejuvenated asphalt is equivalent to that of virgin asphalt, and the workability is slightly poorer; however, the fatigue property and low temperature property have been significantly enhanced. W-oil cannot only improve the pavement performance of aged asphalt, it can also guarantee good safety property and aging property. Therefore, W-oil is of great potential to serve as an asphalt rejuvenator for rejuvenating aged asphalt.

“…However, Hesp and Shurvell [13] found that it could result in poor low temperature performance of rejuvenated asphalt with the WEO content beyond 15%. Hallizza Asili.et.al [14][15][16] also studied the physical and chemical properties of rejuvenated asphalt to prove its application. Zhang et al [17] evaluated the effects of WCO viscosity and acid value on the basic, rheological, and chemical properties of typical rejuvenated asphalt.…”

In order to explore the applicability of waste engine oil and waste cooking oil used in aged asphalt, the effect of waste engine oil and waste cooking oil on aged asphalt recycling was studied through the analysis of the improvement of its physical, chemical, and rheological properties. Six aged asphalt binders with different aging times were obtained by indoor test simulation using the Thin Film Oven Test at 163 °C. Then, waste engine oil and waste cooking oil with five different dosages were added to investigate improvement performances. The results clearly demonstrated that waste engine oil and waste cooking oil could soften and recover the work ability of aged asphalt effectively. Furthermore, the physical, chemical, and rheological performances of six aged asphalts could be improved to normal level of virgin asphalt if the content of waste engine oil or waste cooking oil was suitable. The rheological properties of aged asphalt with waste cooking oil had better improvement than that with waste engine oil. Overall, the good applicability would provide waste oil a much wider service range in asphalt pavement recycling field. It also provided a method of developing new rejuvenating agent with the two waste oils to achieve complex synergism effect. Moreover, it realized the waste cyclic utilization and environmental protection.
