【 摘 要 】

Asphalt performance has important effect on the fatigue resistance performance of asphalt mixture. This research based on the DSR time scanning mode, investigated the constant strain performance of 70 # matrix asphalt and SBS modified asphalt. Based on 50% G∗ 0 to simulate the fatigue performance of two kinds of the asphalt.
