The WMA mixtures were plant produced with a foaming technology commonly used in the United States. This study evaluated the rutting resistance, moisture susceptibility, and fatigue resistance of warm‑mix asphalt mixtures containing high percentages of reclaimed asphalt pavement through laboratory performance tests. RAP content ranged from 0% to 50%, and the mixtures were evaluated using asphalt pavement analyzer rutting, Hamburg wheel‑tracking, tensile strength ratio, Superpave indirect tension, and beam fatigue tests, with hot‑mix asphalt containing 0% and 30% RAP used for comparison. WMA mixtures with high percentages of RAP showed higher rutting resistance, better moisture damage resistance, and improved fatigue performance.
This study evaluated the rutting resistance, moisture susceptibility, and fatigue resistance of warm-mix asphalt (WMA) mixtures containing high percentages of reclaimed asphalt pavement (RAP) through laboratory performance tests. The WMA mixtures were plant produced with a foaming technology commonly used in the United States. RAP content ranged from 0% up to 50%. Laboratory performance tests included the asphalt pavement analyzer rutting test, the Hamburg wheel-tracking test, the tensile strength ratio test, the Superpave ® indirect tension test, and the beam fatigue test. For comparison purposes, hot-mix asphalt mixtures containing 0% and 30% RAP were also evaluated and compared with WMA. The laboratory test results indicated that WMA mixtures with high percentages of RAP exhibited higher resistance to rutting, better resistance to moisture damage, and better fatigue performance.
