Effects of Blending Temperature and Time on Interfacial Diffusion Behavior and Fatigue Response of Virgin–Aged Asphalt Binders
To elucidate the diffusion behavior between virgin and aged asphalt binders and its relationship with fatigue performance, a concentric-circle blending system with a well-defined initial interface was constructed. By varying the blending temperature and time, the interfacial blending process was characterized from the...
