Improving Asphalt Mixture Performance by Partially Replacing Bitumen with Waste Motor Oil and Elastomer Modifiers

Abstract: Featured Application: This work deals with the partial substitution of asphalt binder with waste motor oil and elastomer modifiers in order to obtain improved mixtures for pavement application purposes, which is also compared to an alternative mixture using bio-oil. The featured application of this solution is the production of new asphalt binders and mixtures for paving works in general. Abstract:The environmental concern about waste generation and the gradual decrease of oil reserves has led the way to findi… Show more

“…One of the potential municipal waste materials that can be used to rejuvenate RAP is waste engine oil (WEO) from cars [17,18,19]. The structure of WEO resembles the molecular structures of asphalt with sufficient aromatic content, which leads to coherent bonding by altering the constituents and rejuvenating the aged asphalt [20,21]. Bio-oil has a similar structure and it can be also successfully used as a rejuvenating agent in mix asphalt [22,23,24].…”

“…e structure of WEO resembles the molecular structures of asphalt with sufficient aromatic content, which leads to coherent bonding by altering the constituents and rejuvenating the aged asphalt [7][8][9][10]. However, despite the potential of WEO to serve as a rejuvenator, very few studies evaluated WEO as a rejuvenating agent prior to 2009 [11].…”

“…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.…”
