Segregation in Aggregate Base Stockpiles - Graniterock
Segregation of an aggregate product will likely occur where the ratio of the size of the largest particles to the size of the smallest exceeds 2:1. A ¾″ maximum base product exceeds this ratio and will readily segregate. Segregation occurs in the formation of a traditional conical stockpile.

2020-3-19 · Segregation causes excessive variation in gradation of a product. Segregation can occur virtually anywhere throughout the process of aggregate production after a product has been crushed, screened and blended to its proper gradation. The first likely place for segregation to occur is within the stockpile (see Figure 1).

2015-12-15 · CAUSES OF STOCKPILE SEGREGATION There are many factors that contrib-ute to segregation within a stockpile. Since most stockpiles are created with a belt conveyor, it is important to un-derstand the inherent effects of a belt conveyor on the gradation of a mate-rial. As a belt carries material along the conveyor, a slight bouncing mo-

Aggregate Segregation – Pavement Interactive
Aggregate Segregation. “Segregation” is a term often used in the HMA industry to describe a number of different phenomena. It’s most general definition comes from Stroup-Gardiner and Brown (2000 [1] ): “Segregation is a lack of homogeneity in the hot mix asphalt constituents of the in-place mat of such a magnitude that there is a ...

GUIDELINES FOR SAMPLING OF AGGREGATE MATERIALS
6.1 Truly random samples cannot be obtained from a stockpile after it is built because only the outside of the stockpile can be effectively sampled. In addition, segregation often occurs with coarser particles accumulating on the outside of the pile. 6.2 Sampling from an existing stockpile should only be done when no other alternative is available.
