Hot mix asphalt (HMA) is produced at temperatures between 280° and 320°F. These temperatures ensure that the aggregate is dry, the asphalt binder coats the aggregate, and the HMA mix has a suitable workability. HMA needs to be workable so it can be transferred into storage silos, transported, placed, and compacted.
