lifespan. This study synthesized calcium alginate capsules containing rejuvenator oil, achieving a compressive strength of 18 N and a 75.83% weight loss at 900°C. Capsules were added to asphalt mixes at 0%, 0.5%, and 1% by weight of aggregates. Laboratory tests on unaged, short-term aged (STA), and long-term aged (LTA) samples showed that capsule inclusion did not affect volumetric properties or significantly alter rutting, ITS, or resilient modulus. However, SARA fractionation revealed a 9.4% increase in aromatics content in LTA samples with 1% capsules, indicating enhanced bitumen properties through gradual rejuvenator release.
