Overview

Research finds improved cracking resistance in high-content crumb rubber asphalt with warm-mix additives, suggesting better aging performance.

Key Points

  • Cracking resistance improved in high-content crumb rubber asphalt with warm-mix additives, enhancing its longevity.
  • The optimal dosage of the warm-mix additive was determined to be 0.6%, based on dynamic shear rheometer testing.
  • Analysis utilized both dynamic shear rheometer and atomic force microscopy to assess performance and microstructure.
  • This indicates that enhanced warm-mix asphalt could provide better performance in regions with large temperature fluctuations.
