Whether reclaimed asphalt pavement can be reused multiple cycles has become a focal issue in the industry. This paper investigates macroscopic physical property changes and microscopic four-component alteration mechanisms of recycling asphalt, simulates processes mixtures through laboratory tests, determines mix proportions Marshall test, evaluates performance using high-temperature wheel tracking semi-circular bending freeze-thaw splitting test. The results indicate that after recycling, exhibits poorer rheological property; mixture is improved, low-temperature significantly degraded. solubilization rejuvenator old intensifies with increasing dosage but decreases exponentially number cycles. stability recycled gradually increases cycles, while water shows low sensitivity to After third volume indicators meet regulatory requirement. second anti-cracking deteriorates rapidly. In summary, when undergo special attention should paid restoration their property.
