Fatigue resistance investigation of warm-mix recycled

conducted on warm‐mix recycled asphalt binder, mastic, and FAM with different ageing levels to determine the linear viscoelastic (LVE) limits and strain levels used in fatigue tests. The DSR time sweep test was performed at 3 strain levels to characterize the fatigue behavior of warm‐mix recycled asphalt materials in different scales.
