SUMMARY
Long-term oven aging significantly impacts the resilient modulus of ACW28 asphalt concrete. The discussion highlights that prolonged exposure to elevated temperatures alters the material's viscoelastic properties, leading to increased stiffness and reduced flexibility. This change in resilient modulus is critical for predicting the performance and durability of asphalt mixtures in real-world applications.
