Overview

Randomized trial examines the durability of warm mix-recycled asphalt mixtures in various aging conditions, suggesting material improvements for wider usage.

Key Points

  • This research aims to evaluate the long-term durability of warm mix–recycled asphalt mixtures under aging and freeze–thaw cycles.
  • Laboratory simulations of long-term aging and freeze-thaw cycling on various mixtures.
  • Evaluation of mixture performance and binder properties post-cycling actions.
  • Comparison between WMRA-AE variants and a conventional asphalt mixture.
  • WMRA-AE-100 saw the greatest performance drop after freeze-thaw cycles; the rejuvenated variant (WMRA-AE-100-R) showed the least deterioration.
  • Long-term aging improved rutting resistance but weakened low-temperature cracking and water stability.
  • WMRA-AE-75-R demonstrated durable performance across aging and freeze-thaw conditions, suggesting it as a reliable material for diverse environments.
