Effect of the binary compound method of TOR promoting dissolution and NaOH solution surface treatment on the performance of rubber asphalt

Perspectives on the Application of Waste Materials in Asphalt Based on Molecular Dynamics Simulations: A Review

“…Researchers combined CR with asphalt binders to address the issue of recycling rubber tires. Waste crumb rubber (WCR) has been shown in numerous studies to enhance the high- and low-temperature behavior, durability, antislip properties, and fatigue of asphalt mixtures. − Many techniques, such as Fourier transform infrared spectroscopy (FT-IR), fluorescence microscopy, thermogravimetric analysis (TG), and differential scanning calorimetry (DSC), have been commonly used to interpret the consistency, microstructural properties, and thermal properties of rubber asphalt . The MD technique is also introduced to explain the microscopic mechanism, adhesion and debonding peculiarities, and thermodynamic properties of CRMA.…”

“…To increase the compatibility between CR and asphalt, researchers have made many attempts, , and pretreatment of WCR has been proven to be an effective way. , Pretreatment can remove inert substances from the WCR surface to enhance its surface activity and accelerate the interaction between the WCR and asphalt. Currently, the surface activity of WCR can be increased by thermomechanical, microbiological, and plasma activation methods; the commonly utilized techniques are chemical, mixing oil, and microwave radiation approaches. ,− These methods are shown in Figure …”
