Influence of novel long-chain active composite rejuvenators on interfacial adhesion between aged SBS modified asphalt and aggregate

Research on the effect of rubber powder on asphalt adhesion and resistance to ultraviolet aging

“…The SBS modi ers will be decomposed under UV light, which causing the chemical bonds to break and producing a variety of strongly polar functional groups containing oxygen, sulfur, ammonia and other organic chains. The presence of these functional groups facilitates the crosslinking polymerization of active components in asphalt, thereby enhancing the molecular arrangement and network structure in modi ed asphalt [39] Therefore, the polar component of D is decreased. Throughout the entire process of UV aged, the dispersion component consistently remains smaller than the polarity component, indicating that the latter is predominantly responsible for determining asphalt [40].…”

Regeneration mechanisms of aged SBS modified asphalt from RAP materials: Molecule structure, morphology, phase transition, and interface adhesion characteristics

“…As for the regenerant-III, the adhesion work was restored to 95.49% of the original SBS modified asphalt due to the action of the interfacial reinforcing agent. Han et al, [44] prepared one kind of rejuvenator (HHA) and found that it can restore the surface energy of aged SBS modified asphalt to 82.33% of the virgin sample, which is lower than that of The regenerant-III. And the mechanism of regenerant-III on the interface between asphalt and basalt is drawn in Fig.…”
