In order to study the effect of different rock asphalt contents on the physical and mechanical properties of an asphalt binder and asphalt mixture, the physical and mechanical tests and analysis were conducted. An on-site case was investigated to verify the effectiveness of rock asphalt-modified pavement. The results show that the activation treatment can effectively enhance the molecular polarity of Buton rock asphalt. The “wet process” was used to prepare the Buton rock asphalt-modified asphalt binder, and the high-temperature performance and aging resistance were significantly improved. The modified asphalt prepared by mixing 30% rock asphalt shows the optimum balance between service performance and segregation. The on-site full-scale application of the Buton rock asphalt-modified asphalt pavement showed the good workability and service performance. This research demonstrated the ability of rock asphalt improving asphalt pavement on multiscales. It is helpful for the broader application of rock asphalt in asphalt pavement.

“…The role of individual ingredients such as the asphalt binder and aggregates on mixture performance is readily known. The relevance of binder-aggregate interaction to mixture performance is also recognized in the literature [1][2][3][4][5]. For instance, investigations on the mechanisms of adhesive failure show that these types of failures are significantly influenced by the characteristics of the binder-aggregate interface [6][7][8][9].…”

“…Wei et al studied the relationship between surface free energy and chemical composition of asphalt binder, and used this to explain why surface free energy method is an efficient tool to quantify the interaction [15]. Tan and Guo studied the relationship between surface free energy and conventional metrics quantifying moisture resistance of asphalt mixture (such as the freeze-thaw splitting test and the pull-off test) for cold mix asphalt, and demonstrated that there is good correlation between macro mechanical indicators and energy indices [5]. Clopotel et al used a thermodynamics method to measure physico-chemical interaction in mastics based on glass transition [16].…”

Although the role of individual ingredients of hot mix asphalt (HMA) such as asphalt binder and aggregates on its performance is readily recognized, there is only limited understanding about the interactions between these components and the properties of binder-aggregate interface. In order to study the interactions between asphalt binder and mineral aggregates, an interfacial test method was developed and its effectiveness was evaluated. Interfacial interactions were evaluated by testing thin films of an asphalt binder interfaced with the surface of aggregates under two different modes of loading in shear: sinusoidal oscillation and monotonically increasing. An Interaction Parameter (IP) was proposed to quantify the binder-aggregate interfacial effects. The results show that the methodology used in this study can quantify the effects of interaction between the asphalt binder and mineral aggregates. Furthermore, this research also investigated the interaction of an asphalt binder with the surface of simulated reclaimed asphalt pavement (RAP) aggregates. The results from this research not only provide an insight to the effects of binder-aggregate interaction, but can also help practitioners to better understand the effect of mixing conditions on the properties of mixtures produced using different materials.

“…The second mode is the cracking of the bitumen mortar itself and is called cohesion failure destruction. These two types of failure modes are associated with temperature, oil film thickness, bitumen quality, mineral aggregate surface property and contact surface loading mode and commonly occur in the failure process of mixtures (Arifuzzaman & Hassan, 2014;Falchetto, Moon, & Wistuba, 2016;Guo, Tan & Zhou, 2014;Zheng, Zhao, & Xiang, 2012;Zheng, Chen, & Zhao, 2014). Therefore, when improving the low-temperature cohesive strength of bituminous binders is necessary to enhance the anticracking and anti-loose ability of mixtures.…”

The decay law on the ageing process of the cohesive strength of styrene-butadiene-styrene(SBS)- and polyethylene(PE)-modified bitumens at low temperatures was investigated. The rotated-thin-film oven test was used to age the two types of polymer-modified bitumens. The cohesive strengths at different low-temperature conditions were tested quantitatively according to technology for testing the low-temperature cohesive strength of bitumen. The decay curve of bitumen low-temperature cohesive strengths was drawn, and the embrittlement time of bitumen at different ageing states was obtained according to the decay curve. Results showed that ageing time definitely influenced the attenuation degree of the low-temperature cohesive strength of the two types of polymer-modified bitumens and influenced the appearance of the low-temperature cohesive strength peak, i.e., the bitumen embrittlement time, which advanced after ageing. The lightweight components of polymer-modified bitumen were lost after ageing. The bitumen embrittlement time was advanced, and the sharp attenuation of the low-temperature cohesive strength of bitumen appeared. In the future, bitumen antiageing technology and lighter part pre-supplement technology should be studied in-depth.
