“…When aromatic extract is used as rejuvenator, it was evaluated that temperature plays a crucial role for reaching a high rejuvenation rate for different types of ABs (79). According to the same study on the rejuvenation effect of aromatic extract, it was found that the recovery of rheological properties of aged ABs by applying aromatics was in a lower extent than VW oil with same proportion of added agent.…”

Abstract:Aging is the accumulation process of diverse detrimental changes in molecular structures with advancing age. Resistance to aging is termed durability. Complex molecular systems such as asphalt binder need to be protected against aging. In this paper, a state-ofthe-art review of anti-aging technologies used to prohibit or to rejuvenate the aged asphaltic materials is provided. The kinetics of molecular structures during aging and the group of molecules affected mainly are discussed. The latest developments on anti-oxidation and rejuvenation technologies are given as well showing the impact of anti-aging technologies for the asphalt binder. INTRODUCTIONThe transportation industry consumes approximately 32.6% of the total energy produced in the European Union and almost 28% in the United States. In parallel with the increasing cost and the strong global demand for low prices of the paving materials and operations, the rapid aging of asphalt pavements due to the aggressive environmental conditions is becoming a pragmatic concern for the whole transportation industry. Avoiding the aging of asphalt binder or preventing the undesirable effects of ultimate degradation of asphalt mixes after certain time are among the major topics in which governmental authorities and infrastructure contractors have focused. Strategies, such as preventive maintenance techniques and reconstructive treatments of asphalt pavements, have been deployed in the last years to deal with the aging phenomena of asphaltic materials. Also, the utilization of additives as the countermeasure to prohibit aging of asphaltic materials (i.e., anti-oxidants) and to restore materials' characteristics (i.e., rejuvenators) shows significant benefits in these efforts. Asphalt binder (AB) is composed of an extremely large number of different types of organic molecules ranging from paraffins to alkyl polyaromatics containing heteroatoms of nitrogen (≤ 2%), oxygen (≤ 2%), sulphur (≤ 6%) and traces of metals such as vanadium and nickel. These molecules are separated in categories based on the chemical reactivity and the polarity of organic molecules. The dispersion of polar organic molecules in a medium of less polar molecules and their interaction are highly associated with the performance-related properties of ABs and their susceptibility under oxidation. When the material is oxidized, the state of molecular dispersion within the binder alters and new polar molecules are produced.Several studies have reported on the oxidation chemistry of AB, the main factors influencing aging and how aging can be addressed using chemical additives and anti-aging technologies. In this paper, focus was given to combine information of the most valuable researches which were validated for several times for the aged ABs and the anti-aging technologies. The current and concise state-of-the-art review on aging and anti-aging is provided with highlighting the chemistry of AB and the chemical interaction of anti-aging additives on them.

“…Every image was built up by 256 Â 256 pixels. The elastic modulus, adhesion, deformation and dissipated energy were determined as described elsewhere [10,28,29]: The approaching and retraction force curves are generated for each pixel and the mechanical properties are mapped; to obtain the elastic modulus, the retraction curve are fitted using the DerjaguineMüllereToporov (DMT) model [30]; the adhesion is measured as the minimum force in the retraction curve; the deformation is calculated from the approaching curve at a force value of 15% of the peak force; and the dissipated energy is defined as the area in between the approaching and retraction curves. Offline data analyses were performed using Bruker Nanoscope Analysis 1.40.…”

“…The researchers also claimed more amount of RAP within the recycled mixtures could be accessible by implementation of waste cooking oil [10]. Yu et al (2014) implemented waste vegetable oil and an aromatic extract in order to rejuvenate the aged bitumen. The rejuvenator was used to enhance the rheological properties of the aged bitumen.…”

“…It is reported that the use of these agents could modify the chemical structure of the aged bitumen and thus the mechanical behaviour of the mixtures. The researchers evaluated the samples at both macro-and micro-scales and found out that the characterization of rejuvenating impact on the aged bitumen could gain the advantage of improved recycling for bituminous materials [11].…”

-The present asphalt pavement industry faces two major issues. These two major issues are the increasing demand for ecofriendly asphalt mixtures and the costs of raw materials. The use of reclaimed asphalt pavement will be an essential attempt to reduce the costs of aggregates and bitumen in the final mixture. On the other hand, the main challenge for implementing RAP (Reclaimed Asphalt Pavement) is to overcome quality issues. RAP doesn't perform like a fresh pavement since it is an aged material and needs to be improved. This puts forward the requirement for extra practices like using of rejuvenating agents. Since bitumen loses its oily constituents when it ages, the use of oil-containing additives can be effective. In this study, two kinds of waste oils were used to rejuvenate aged asphalt mixture. Optimum contents of Waste Engine Oil (WEO) and Waste Vegetable Oil (WVO) additives were determined in order to implement various RAP contents. The effects of these two oily based rejuvenators on utilization of RAP in bituminous mixtures were investigated. The results represented that the use of WEO and WVO as rejuvenators for mixtures containing RAP enhances the amount of RAP used in bituminous mixtures.
