Wording in this test method infers that it is measuring the amount of clay contamination in a sample, however the amount of clean dust of fracture (non-clay fines) in crushed fine aggregate will affect the readings for this test. Revised wording is needed to clarify that the test also measures clay-sized particles that are present in clean dust of fracture.
Clay-like fines; Field testing--pavement surfaces; Field testing--soil; Fine aggregate; Granular soil; Plastic fines/dusts; Sand equivalent value; Soil (paving applications);
