warm mix asphalt temperature ranges

Temperature Range for Hot Mix Asphalt Top West Asphalt

Hot mix asphalt gets its name from the fact that it is mixed, transported to the job site, and poured at a high temperature. Exactly what that temperature is varies according to the exact grade of asphalt. More viscous asphalt requires higher temperatures. In general, though, the minimum temperature ranges from approximately 107 C to 121 C.

Jan 15, 2020  When it arrives at the job site, hot-mix asphalt is normally between 275 and 300 degrees Fahrenheit. For the initial rolling, the temperature of the mix needs to be between 220 and 290 degrees Fahrenheit. If the mix temperature falls below approximately 185 degrees Fahrenheit before the final compaction, it will be too stiff to compact properly.
