Sieve Analysis of Coarse Aggregate: The Test Procedure ...

Gradation, or particle size distribution, is the dispersal of individual particle sizes across the entire sample. Aggregate gradation is typically reported in graphical form by plotting each of the particle sizes on a semi-logarithmic chart and drawing a best-fit curve between the points. The full procedure is outlined in ASTM C136 (AASHTO T-27).
