The global asphalt production growth rate exceeded 10% in the past decade, and over 90% of world’s road surfaces are generated from materials. Therefore, issue aging has been widely researched. In this study, thin films under various natural conditions was studied to prevent distortion indoor simulated extraction samples impacting aged asphalt. styrene–butadiene–styrene (SBS)-modified at four different locations on an surface. characteristics binders across structural layers were revealed using Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), linear amplitude scanning (LAS). results indicate that behavior functional group surface differs other conditions; fatigue life 4 months equates 16-month within dense-graded After 8 aging, smoothness significantly compromised. Inside porous pavement, is more likely interact with water molecules than inside dense pavement cracks, variations roughness reduction also significant.
