• Increasing recycled aggregate content reduces both permeability and bending load of cement-stabilized permeable recycled aggregate material.
• Recycled aggregates diminish energy dissipation capacity, indicating altered damage evolution under cyclic loading.
• A robust relationship between initial damage and fatigue life was established, enabling a predictive model for fatigue performance.
• A fatigue damage assessment method based on strain evolution and energy dissipation was developed to support low-carbon, permeable, and durable roadway design.
