    Warm-mix asphalt is produced at the mixing plant using various technologies. Mechanical water injection systems connected to the mixing plant add a small amount of water, approximately 2 percent, to the liquid asphalt cement. The injected water immediately boils to expand the volume of liquid asphalt by creating air bubbles or foamed liquid asphalt.

    Asphalt described as warm mix is typically heated to between 100°C and 140°C, around 40°C less than hot-mix asphalt. Nynas also offer a ‘half-warm’ mix whereby asphalt is produced at between 70°C and 100°C. Lowering the mixing temperature of asphalt not only reduces the energy needed to heat raw materials during production, but also generates fewer emissions.

  • Warm Mix Systems - Astec Inc.

    The Astec warm mix system achieves a lower temperature at a lower cost by eliminating the need for additives or special asphalt cement. Instead, the Astec warm mix system injects a small amount of water into the liquid AC to create microscopic steam bubbles. These small bubbles act to reduce the viscosity of the liquid AC, allowing the mix to be worked at lower temperatures.
