Stockpile vs Aggregate What's the difference?

Noun ()A mass, assemblage, or sum of particulars; something consisting of elements but considered as a whole.() A mass formed by the union of homogeneous particles; in distinction from a compound, formed by the union of heterogeneous particles.() (mathematics, obsolete) A set (collection of objects).(music) The full chromatic scale of twelve equal tempered pitches.

Contending with stockpile segregation, product

2020-3-19  A uniform aggregate product is essential to producing high quality asphalt or concrete. The fluctuating gradation of a segregated aggregate product makes it nearly impossible to produce an acceptable asphalt or concrete product. A given weight of smaller particles has a larger total surface area than the same weight of larger particles.

This approach will allow the sampling agency to use a particles rolling to the outside base of the pile. For coarse or mixed coarse and fine aggregate, every effort should be made

Practices for Unbound Aggregate Pavement Layers

2 天前  As the material moves down the side of the stockpile, larger particles tend to move down to the bottom (owing to higher momentum), whereas finer materials tend to settle into the side of the pile. Such spatial distribution of aggregate particles of different sizes at different portions of the stockpile results in pronounced segregation.

While visiting a plant site, Materials & Research noticed the aggregate stockpile had large amounts of what appears to be lightweight aggregates (lightweight pieces) on Phase I of the project as shown in Figures 1 and 2. This was a concern due to the large quantities observed in the stockpile.

Minimize Aggregate Segregation and Increase

Aggregate segregation is typically caused by one of 5 main issues: Mix design: Open-graded mixes and low asphalt binder content mixes are particularly prone to segregation. Stockpiling: If aggregate is loaded on top of a conical stockpile then larger aggregate sizes are more likely to roll to the outside and bottom.
