Implication

Investigation reveals mechanical performance in asphalt mixtures varies by skeletal structure, indicating crucial design insights.

Key Points

  • Under splitting load, the asphalt mixture skeleton primarily transmitted compressive stresses.
  • Over 65% of contact force chains were due to compressive stress across three asphalt mixtures.
  • The blend of coarse aggregates significantly improved the skeleton's stability and reduced crack formation.
  • SMA-20 exhibited superior crack resistance compared to AC-20 and OGFC-20, indicating variation in performance.
