Overview

Experimental study demonstrates enhanced thermo-oxidative aging resistance in zinc oxide-modified asphalt mixtures, suggesting improved road pavement durability.

Key Points

  • Zinc oxide modification increases the thermo-oxidative aging resistance of asphalt mixtures while improving resistance under both monotonic and repeated loading.
  • A concentration of 5 wt% zinc oxide achieves the best overall performance, enhancing hot-mix asphalt resilient modulus and resistance to moisture damage.
  • Evaluation using the Marshall method, indirect tensile strength, and resilient modulus tests highlights nano-particle potential for durable road pavements.
