Hot Mix Asphalt (HMA) is made up of primarily mineral aggregates and asphalt binder that are heated and mixed in a plant at an elevated temperature (~ 150oC), placed with a paver at a lower but sufficiently high temperature (~ 140oC), and compacted with rollers before the temperature drops below a certain level, typically 90-100oC.
