Research on the interfacial degradation mechanism of field-aged SBS-modified asphalt binder under freeze–thaw effects based on molecular dynamics simulations
Key Points
Interfacial degradation was significantly impacted by freeze-thaw cycles, influencing overall binder performance.
Molecular dynamics simulations showed that SBS-modified asphalt displays unique properties under these conditions, revealing a degradation pattern.
Assessment of degradation mechanisms was carried out through advanced simulations, focusing on molecular interactions and structural integrity.
Findings highlight the need for enhanced materials to improve the durability of asphalt in harsh environments, potentially guiding future development.
