Overview

Randomized trial evaluates zinc diethyldithiocarbamate's effects on rheological properties in asphalt, suggesting improved durability.

Key Points

  • This study aims to evaluate the effectiveness of zinc diethyldithiocarbamate (ZDC) in enhancing the aging resistance and rheological properties of SBS-modified asphalt.
  • Conducted physical property tests, dynamic rheological analysis, MSCR, and FTIR assays.
  • Evaluated the effects of ZDC in SBS-modified asphalt before and after thermo-oxidative and UV aging.
  • Assessed performance changes and chemical properties of asphalt binders.
  • ZDC improved deformation resistance and elastic recovery in SBS-modified asphalt.
  • 5% ZDC dosage reduced carbonyl index by 36.48% after thermo-oxidative aging and 21.89% after UV aging.
  • ZDC lowered non-recoverable creep compliance variation by 35.32% and 41.46% before and after thermo-oxidative and UV aging, respectively.
