Effect of SBS Copolymer Molecular Structure on the Long‐Term Aging and Resilience of Asphalt Binders: A Multiscale Morphological Study

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Vinyl content governs the long‐term ageing resistance of SBS‐modified bitumen. Multiscale AFM, FM, SEM, and FTIR analyses show that low‐vinyl SBS copolymers (L‐SBS, B‐SBS) undergo pronounced bee‐phase growth, stiffening, and network fragmentation after PAV ageing, whereas high‐vinyl variants (HV‐SBS, DB‐SB) retain their morphology and chemistry ...
