The term "segregation" in asphalt paving specifically refers to the uneven distribution of materials within the asphalt mix. When segregation occurs, the components of the mix, such as aggregates and asphalt binder, are not uniformly combined, leading to areas that may have different properties, such as strength, density, or durability. This uneven distribution can result from various factors during the mixing, transport, or placement processes, ultimately affecting the performance of the pavement.

Understanding this concept is crucial in ensuring the quality and longevity of asphalt pavements, as it can lead to premature failure if not properly managed. Proper mixing techniques and careful handling during placement are essential to minimize the risk of segregation.
