Warm Mix Asphalt Cost and Benefits - thebalancesmb.comDifferences between Warm Mix and Hot Mix Asphalt. Warm mix asphalt is produced using temperatures 30 to 120 degrees Fahrenheit lower than what is used for traditional hot mix asphalt. Less energy is needed to heat the warm mix asphalt, so it uses less fuel, decreasing the plant's carbon footprint.

Compacting Hot-Mix Asphalt Pavements: Part I | Roads & Bridgesof the mix decreases, the amount of raveling also will decrease. An asphalt-concrete mix must be fully compacted before it cools to a temperature of about 175 F. At temperatures above this value, the mix is normally still warm enough for the compaction equipment to reorient the aggregate particles into their densest configuration. Below that temperature, however, the mix
