specifications for aggregates are detailed in Section 904 and other sections for the various types of construction. These specifications are to be followed when inspecting aggregates. There are two general types of requirements for aggregate: quality and gradation. _____

Gradation and Size - Pavement Interactive

A gradation test is performed on a sample of aggregate in a laboratory. A typical sieve analysis involves a nested column of sieves with wire mesh cloth (screen). See the separate Mesh (scale) page for details of sieve sizing.. A representative weighed sample is poured into the top sieve which has the largest screen openings.

Fine gradation. A gradation that, when plotted on the 0.45 power gradation graph, falls mostly above the 0.45 power maximum density line. The term generally applies to dense graded aggregate. Coarse gradation. A gradation that, when plotted on the 0.45 power gradation graph, falls mostly below the 0.45 power maximum density line.
