Thermal aging behavior characteristics of asphalt binder modified by nano-stabilizer based on DSR and AFM

In order to clarify the effect of thermal aging on the nano-stabilized modified asphalt binder, TINUVIN 770 (T770) hindered amine light stabilizer of nanoscale was selected as aging modifying agent to prepare modified asphalt. The impact of thermal aging on the rheological properties of T770-modifie...

The surface roughness variation of T770-modified asphalt was characterized by using atomic force microscope throughout the thermal aging process.
