“…It can also alter the adhesion between aggregate and asphalt [9] and reduce ductile performance [16]. A recent study concluded that WEO could provide promising performance using greater amounts of waste materials [17]. However, previous studies do not explain the extent of RAP to which WEO can be used as a rejuvenating agent.…”

The use of large proportions of reclaimed asphalt pavement is necessary to meet the increasing demand for road construction materials in a sustainable way. One of the challenges of using a greater percentage of reclaimed asphalt pavement (>30%) is the greater stiffness of mixes incorporating it. While this stiffness problem is usually resolved by using different commercial rejuvenators, there are circumstances in which commercial rejuvenators are not available. Therefore, this study evaluates the potential of using waste engine oil as a substitute for commercial rejuvenators for the higher percentage of reclaimed asphalt pavement that could meet the increasing demand in a more sustainable way. To assess the possibility of using a higher percentage of reclaimed asphalt pavement in road construction, different percentages of reclaimed asphalt pavement (30%, 40%, and 50%) are used. Following the property of the aged binder, three different percentages (7%, 13%, and 20%) of waste engine oil are considered. Each percent of waste engine oil is incorporated with one of the three mixes. The mixes (with the minimum required Marshall criteria) are evaluated for different properties, namely, their indirect tensile strength, resilient modulus, and durability. Finally, those properties are compared to those of the mixes rejuvenated by commercial rejuvenators. It is observed that, for the aforementioned properties, 7% to 13% of waste engine oil is identical to the commercial rejuvenator for the mixes with 30% to 40% of reclaimed asphalt pavement.

“…Several studies have supported the use of waste materials in asphalt mixtures, namely, as a partial substitute of virgin bitumen (Fernandes et al, 2017a(Fernandes et al, , 2017b(Fernandes et al, , 2018 or rejuvenating agent (Jia et al, 2014;Kamaruddin et al, 2014), as bitumen modifier (Costa et al, 2017a;Liang et al, 2015;Lo Presti et al, 2014) and also as partial substitute of aggregates (Costa et al, 2017b;Ranieri et al, 2017;Wu et al, 2007). According to the results presented in the mentioned works, these asphalt mixtures with waste materials present a mechanical performance similar to or better than that of conventional asphalt mixtures, attesting the potential of these alternative solutions.…”

“…Additionally, recycled engine oil bottoms are used in countries with a cold climate to decrease the lower temperature of the bitumen performance grade with the aim of reducing the low-temperature cracking phenomenon (Institute, 2016;Li et al, 2017). Moreover, both waste engine oil products can be partial substitutes of bitumen, together with waste or virgin polymers, showing a performance better than that of a conventional bitumen or commercial modified binders (Fernandes et al, 2018).…”

The incorporation of waste materials in asphalt mixtures has driven several studies mainly focused on improving their mechanical performance while minimizing the use of virgin materials. However, these could only be considered cleaner solutions for road paving works if their production and application do not present additional risks for human health and the environment. Therefore, this study aims at assessing the carbon dioxide emissions and possible leachates of stone mastic asphalt mixtures produced with high rates of different waste materials for binder modification or material recycling. Thus, a chemical analysis of eluates that were in contact with those mixtures and an estimation of the carbon dioxide emissions associated with their production and transportation were carried out under different scenarios. In conclusion, these mixtures comply with the established specifications for hazardous leachates. The addition of waste materials to these mixtures decreases carbon dioxide emissions, especially for recycled stone mastic asphalt mixtures with 50% reclaimed asphalt pavement material and bitumens modified with waste materials. Thus, the studied mixtures are innovative solutions for future use in pavement maintenance and rehabilitation operations, in line with the circular economy concept.

“…Waste Engine Oil (WEO) is capable of recycling RAP, protecting the environment, saving and reducing the resources as well as the cost of the project which can be signed for the road maintenance [13]. In order to minimize the use of bitumen in the binder content, the use of WEO has been studied with different compositions and resulted in promising performance by using the rejuvenators [9]. Due to the loss of high oil contents such as saturates aromatics resins and asphaltenes the process of asphalt aging started.…”

Environmental and economic demands prompt to transportation agencies to increase in the use of Reclaimed Asphalt Pavement (RAP) in asphalt pavements. The use of RAP in pavements often require a rejuvenator to reduce the cracking. Estimating a best rejuvenator dosage is crucial to increase its advantages. Large quantity of waste oils from automobiles and restaurants can inflict adverse impact if it is not properly disposed. Recycling of these waste oils can be a suitable option, to reduce the use of natural resources and economic benefits. In this study, three rejuvenators were explored such as Waste Engine Oil (WEO), Waste Vegetable Oil (WVO) and Waste Brown Grease (WBG) with dosages of 5%, 10% and 15%. Physical testing (i.e. penetration, softening point, flash & fire point and ductility) were conducted in the lab on virgin and RAP binder with rejuvenators. WEO and WVO helps in softening when mixed with RAP binder. According to the results, both WEO and WVO can improve the properties of the RAP binder but WBG gives a little bit improvement.
