Unveiling the influence of aggregate particle morphology on structural uncertainty in asphalt concrete via digital composite modeling

Puntos clave

• Structural uncertainty in asphalt concrete is significantly shaped by aggregate particle morphology and distribution.
• Analyzed four different particle shapes, showing that variations can alter the material's performance characteristics.
• Digital composite modeling techniques were applied to simulate the microstructural behavior of asphalt concrete mixtures effectively.
• These findings highlight the need for consideration of particle morphology in asphalt design processes to improve durability.
