Segregation in asphalt can happen when different particle sizes separate during production, transport, and placement. It isn’t controlled by one simple factor; it results from a combination of aggregate gradation, moisture, temperature, binder content, mixing efficiency, stockpile handling, and paving procedures. Because of this, simply changing the mix type does not guarantee a universal decrease in segregation. There isn’t consistent, across-the-board data showing that segregation has declined over the last decade solely due to changes in mix types. Different regions, materials, and plant practices can produce different trends, so making a blanket claim isn’t reliable. In practice, reducing segregation focuses on proper design and process controls—ensuring good gradation, appropriate binder content, stable temperatures, and careful handling from plant to pave.
