What does segregation refer to in the context of aggregate production?

Segregation in the context of aggregate production specifically refers to the separation of well-graded materials into individual sizes based on their density and the effects of gravity. When aggregates of different sizes are mixed together, during handling, transporting, or placing, the larger particles tend to settle to the bottom due to their greater weight. This can lead to a concentration of larger aggregates in some areas while finer materials may be left in others, creating a non-uniform distribution. This can negatively impact the performance of the final mixture, affecting its strength, stability, and durability. Understanding segregation is crucial for ensuring a consistent and high-quality aggregate mix, which is essential for successful construction projects.
