What problem is primarily associated with stockpiles built using a conveyor system?

The primary problem associated with stockpiles built using a conveyor system is segregation. When materials are conveyed and piled, the differing sizes and weights of aggregate particles can lead to a separation of these components. Larger and heavier particles tend to settle towards the bottom, while finer materials may be thrown to the top or sides of the pile. This stratification results in a non-uniform mixture when the stockpile is later used, potentially affecting the quality and performance of the final asphalt or concrete product. Uniformity in aggregate size distribution is crucial for achieving consistent mixing and optimal physical properties in construction applications. Addressing segregation requires careful monitoring during the stockpiling process, as well as methods to reduce or eliminate the effects of segregation prior to use.
