Hot Mix Asphalt (HMA) for local agency applications WSDOT

Hot Mix Asphalt (HMA) is a combination of aggregate and asphalt binder mixed at an elevated temperature to form a hard, strong pavement construction material. HMA allows mixes to be designed in the laboratory at four different levels (50, 75, 100, and 125 gyrations) simulating four different 20-year traffic levels in the field.
