Overview

Modeling asphalt mixtures using discrete element method reveals size effects on crack propagation and force distribution.

Key Points

  • Peak loads in asphalt mixtures decrease with increased thickness, indicating a size effect.
  • Crack paths become more complex with larger particle size and higher fractal dimension.
  • Coarse aggregates can inhibit crack propagation in mixtures significantly.
  • Force chains exhibit distinct patterns before and after peak loads, affecting crack behavior.
