“…Aging indices were obtained to investigate the aging characteristics of asphalt mixtures. Sengoz (2003) implemented ITS in order to assess the aging and moisture susceptibility of HMA mixtures with various air void contents [24]. Another study on short-and long-term aging behaviour of rubber modified asphalts conducted by Liang and Lee (1996) showed that the aging causes the increasing of tensile strengths [25].…”

-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.

“…Generally, it is believed that an optimum asphalt film thickness of about 9-10 microns is necessary to ensure durability and fatigue resistance of asphalt mixtures [18,29]. However, differences in the shear strength of the specimens with various asphalt film thicknesses are not obvious based on the results mentioned above.…”

“…Research efforts have been made to investigate the influence of interfacial bonding conditions on the mechanical properties of asphalt mixture. Interfacial bonding in the adhesive zone due to stone surface morphology and asphalt film thickness often have a significant influence on the failure mechanism [16][17][18]. Therefore, more comprehensive and accurate knowledge of the interface is necessary to better understand the asphalt-aggregate systems, and some significant work, such as shearing fracture mechanism, needs to be done.…”

In order to investigate the mechanical behavior of asphalt-aggregate systems subjected to direct shear loading and reveal the shear failure mechanism, four groups of direct shear tests were conducted on composite specimens under different experimental conditions with a self-manufactured direct shear test apparatus at 25°C. Comparative studies were conducted to evaluate the effects of stone surface treatment, asphalt film thickness and loading rate on the shear mechanical behavior of asphaltaggregate specimens. Results showed that two kinds of the complete stress-displacement curves, including the general single-peak curve and the first-known double-peak curve, were clearly observed for each condition. In addition, the internal failure mechanisms were analyzed based on qualitative and quantitative methods. It can be concluded that the potential failure modes of the direct shear test include adhesive failure at the asphalt-aggregate interface and cohesive failure within the asphalt film. The research results enhance understanding of the shear mechanical behavior and failure mechanism of asphalt mixture, and also provide a reference for the interfacial failure.
