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.

PDF Gradation effects on hot mix asphalt - IJSER

Abstract: Well gradation in hot mix asphalt (HMA) is as important as in soil. It is measured in density of a material and is the interlocking of particles. The strength of these particulate masses is dependent on it. If the material is strong enough but its gradation is poor, slippage over amongst the particles occurs leading to
