WebFigure 1 shows the typical grading envelopes of the two fill types. Frictional fills are composed of combinations of sand and gravel, while fine-grained fills cover a wide spectrum of gradings ranging from silty sands and gravels to silty clays. It is to be noted that there is some overlap in grading envelopes at the coarser fill fractions. http://www.es-enterprise.com/grading-and-drainage-work.html
