“…Similarly, waste mineral oils can be reused as rejuvenators without further refinement [ 115 ], although vegetal oil-based rejuvenators usually require lower doses than the ones based on petroleum to achieve similar performance [ 116 , 117 , 118 , 119 , 120 , 121 , 122 ]. Another green option to produce rejuvenators is the use of organic waste to obtain bio-oil [ 123 , 124 , 125 , 126 , 127 , 128 ]. Although the road performance of bio-oil-rejuvenated asphalt mixtures varies greatly (it depends on the raw biomass treated, the bio-oil production process, etc.…”

The use of self-healing asphalt is a good option to extend the lifetime of roads and to improve the sustainability of pavement management systems. A bibliometric analysis based on the Scopus database was carried out to review the global research related to self-healing asphalt from 2003 to 2018 and to identify relevant quantitative characteristics from the research in this period. The results from this analysis revealed that the number of accumulated publications followed an exponential growth, which confirmed the relevance that this research topic has gained during the last years. The study revealed that China was the most productive country, followed by the Netherlands, where the most prolific institution is located: Delft University of Technology. Some important research features of the two main approaches most frequently used to develop asphalt mixtures with enhanced self-healing abilities (external heating and encapsulated rejuvenating agents) are compiled in this work.

“…Bio-oil from the pyrolysis of biomass can be used as a binder in asphalt, not only because it is renewable, but also due to its low levels of heterogeneous atoms, such as sulphur (almost nil) and nitrogen (0.5% wt) [26,41,42,44], as well as the presence of high levels of phenols, such as phenolic monomers and pyrolytic lignin in the bio-binder structure, which are derived from the degradation of lignin to some extent. These compounds account for the potential of the use of bio-oil in asphalt [66]. The rheological properties of bio-oil as a bio-binder have been compared with those of petroleum resources [67].…”

Bio-oil is a promising source of chemicals and renewable fuels. As the liquid phase obtained from the pyrolysis of biomass, the composition and amount of bio-oil generated depend not only on the type of the biomass but also on the conditions under which pyrolysis is performed. Most fossil fuels can be replaced by bio-oil-derived products. Thus, bio-oil can be used directly or co-fed along with fossil fuels in boilers, transformed into fuel for car engines by hydrodeoxygenation or even used as a more suitable source for H2 production than biomass. On the other hand, due to its rich composition in compounds resulting from the pyrolysis of cellulose, hemicellulose and lignin, bio-oil co-acts as a source of various value-added chemicals such as aromatic compounds. This review presents an overview of the potential applications of bio-oils and the pyrolysis conditions under which they are obtained. Then, different extraction methods for value-added chemicals, along with the most recent developments, are discussed and future research directions for bio-oil upgrades are highlighted.

“…Based on the results of researches, bio-oils which are extracted from two sources: plantbased and animal-based [73], in addition to the bio-crude oil have been vastly explored as rejuvenating agents. Zhang et al [74] studied the impact of waste wood bio-oil (rejuvenator with 10%, 15% and 20% concentration levels) on PAV-aged asphalt.…”

A Review on the Durability of Recycled Asphalt Mixtures Embraced with Rejuvenators

Reclaimed asphalt pavement (RAP) has received much attention recently due to its increased use in hot mix asphalt (HMA) pavements to enhance pavement sustainability. The use of aged asphalt in RAP, which is highly oxidised and has lost its properties due to exposure to traffic loads and climatic conditions throughout its lifespan, can cause asphalt mixtures to stiffen and embrittle, thus negatively affecting the behaviour of asphalt mixtures. This issue may be resolved by including rejuvenating agents that can restore both physical and rheological properties of aged asphalt by increasing maltene fractions and decreasing asphaltene. However, the high restoration capacity of any kind of rejuvenating agent does not assure the durability of restored aged asphalt. This study explored the performance and durability of rejuvenated asphalt mixtures embedded with several types of rejuvenators identified from the extensive literature review. The study serves as a significant reference to predict future challenges in rejuvenating aged asphalt.
