What is a significant concern if segregation occurs during asphalt application?

Segregation during asphalt application is a significant concern primarily because it leads to inconsistent performance of the asphalt. When segregation occurs, the mixture of asphalt can become uneven, resulting in areas that have different aggregate sizes and asphalt binder content. This inconsistency can create weak spots and lead to premature failures such as cracking or raveling. The uniformity of the asphalt mix is crucial for ensuring that the pavement performs well under traffic loads and environmental conditions. By having a consistent mix, the asphalt pavement can achieve the desired durability, strength, and performance.

The other options do not address the core issue associated with segregation. Improved texture may be desired, but segregation actually leads to a poorer surface quality. Reduced costs can be tempting but aren't directly related to the implications of segregation, which typically would lead to increased maintenance costs in the long run. Similarly, a longer lifespan is not guaranteed; in fact, segregation might contribute to a shorter lifespan due to the inconsistency in the material properties.
