The benefits of warm mix asphalt, such as reduced energy consumption, lowered emissions, and elimination of visible smoke, are well-known in the asphalt paving industry and the latest generation of the Astec warm mix system simplifies production of warm mix asphalt.
- 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
