UV aging behavior evolution characterization of HALS-modified asphalt based on micro-morphological features
To clarify the effect of Hindered amine light stabilizer (HALS) on ultraviolet (UV) aging behavior of asphalt binder, the evolution history Arduino Boards and characteristics of the UV induced micro-structure of modified asphalt were characterized.Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM) were used to analyze the microsco
