Abstract This study developed UV‐responsive microcapsules to enhance the self‐healing properties of asphalt, addressing limitations low survival rates and single‐release mechanisms in current encapsulated rejuvenators. The microcapsules, featuring a urea‐formaldehyde shell embedded with polydopamine‐coated black phosphorus nanosheets (BP/DA) microalgae bio‐oil as core, can convert solar energy into thermal energy, promoting proactive asphalt materials. BP/DA expands microcapsules' light absorption range, enhancing their photothermal conversion efficiency. When incorporated styrene‐butadiene‐styrene (SBS)‐modified at 1.5% dosage, (BP/DA/MC) improved mechanical properties: ductility increased by 13.7%, softening point rose 2%, penetration decreased 3.3%. storage modulus (G′) 46 64°C 35.9% 24.3%, respectively, compared SBS asphalt. Additionally, rate BP/DA/MC/SBS 209.7%, healing index (HI) 78.16%. also demonstrated excellent conversion, increasing asphalt's temperature 22.6% under identical lighting conditions. research offers new method for developing intelligent multi‐mechanism activation, providing theoretical support future third‐generation microcapsule‐based remote‐controlled release activation response.
