3 Common Aggregate Stockpile Problems

In other words, smaller pieces of aggregate tend to migrate downward through the stockpile, slipping through the cracks between larger particles. If you happen to use the entire stockpile at one time, this shouldn't pose a problem, since the aggregate will become evenly dispersed during the mixing process.

Stockpile - an overview | ScienceDirect Topics

Six stockpiles of aggregates (19.00, 9.50, 4.75, 2.36, 0.30, and 0.075 mm) were used to produce the base and modified asphalt mixtures, where stockpiles were coarse aggregates and others were fine aggregates. The Superpave uses the nominal maximum aggregate size (NMAS) of the aggregate to categorize mixtures and define graduation requirements.

Contending with stockpile segregation, product quality ...

Although placing product in a stockpile endangers its quality, stockpiling is a vital link in the aggregate production process. It is a storage method that ensures material availability. The rate of production often differs from the rate at which the product is required for a given application, and stockpiles help to absorb the difference.
