REVIEW OF AGGREGATE BLENDING TECHNIQUES
A number of aggregate blending methods have been proposed and used since contractors, plant operators, and aggre by measuring the distances from each aggregate to a point in the specification area and applying the principle of moments. For example, blend three aggregates using the triangular-chart method.

Material Blending Stonemont Solutions
Stonemont Software provides the ability to quickly blend to the maximum density line on a .45 power chart. It is used often as a toggle to see the difference between blending to meet a specification and blending to max-density. A common constraint includes specifying a fixed percentage of component material to use in the blend.
