Abstract
The current study examined the properties of warm mixture asphalt (WMA), which contains nano- and polypropylene polymer (PP) polymers. Unmodified WMA and modified WMA both include 3% PP and NS (2–5%) by weight of asphalt respectively. The tests used to assess performance include the tests for fatigue resistance, rutting resistance, and moisture resistance. The results show that adding Nano-silica and Polypropylene enhances WMA performance. The results also show that adding polypropylene and nano-silica to asphalt as modifiers increases the asphalt's performance and durability.
