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).

A sand frame is placed on the flask, and both are then filled with sand from a hopper. Next, the machine table travels upward to squeeze the sand between the pattern plate and a stationary squeeze head. The squeeze head enters into the sand frame and compacts the sand so that it is level with the edge of the flask.
