Overview

Experimental and Numerical Analysis Evaluates Fatigue Performance and Self-Healing in Asphalt Mixtures.

Key Points

  • This study examines the fatigue mechanisms and self-healing abilities of FMA-13 mixtures with different asphalt contents.
  • Conducted four-point bending tests to evaluate fatigue performance of FMA-13 mixtures.
  • Performed finite element simulations in Abaqus to analyze fatigue mechanisms.
  • Investigated self-healing capabilities through intermittent fatigue tests under various loading conditions.
  • FMA-13 mixtures show increased fatigue life with higher asphalt-aggregate ratios.
  • At 10 Hz, 15 °C and 600 με, fatigue life of FMA-13(9.0) is 9.72 times greater than AC-13.
  • Under intermittent loading, FMA-13(7.0) recovers 79.5% of its initial value, compared to 6.4% for AC-13.
