www.environment.nsw.gov.auDirty gravels are of two types: those with non-plastic (silty) fines (GM) and those with plastic (clayey) fines (GC). The determination of whether the fines are silty or clayey is made by the three manual tests for fine-graded soils. 3. If a soil is a sand, the same steps and criteria are used as for gravels in order to determine
