D422-63(2007) D2217 D4221-99(2005) Percent fines ASTM D1140-00(2006) Refs. 1, 4, 5 Percent of weight of material finer than No. 200 sieve Atterberg limits ASTM D4318-10 Refs. 2, 3, 5, 6, 7, 8 Liquid and plastic limit, plasticity index, shrinkage factor (limit) D4943-08 Specific gravity ASTM D854-10 Refs. 2, 4 Specific gravity, apparent specific gravity, bulk unit weight sufficiently fine to eliminate internal voids in the intact rock Boiling should not be used for de-airing. Method can be used for rock, after grinding. D5550-06 C127-07 Radiography ASTM D4452-06 Ref. 9 Qualitative test of sample quality Description of soil and rock ASTM D2487-10 Description of soil from visual-manual examination D2488-09a D4452-06 C294-05 SOILS—MOISTURE-DENSITY RELATIONS Bulk unit weight ASTM C127-07 Bulk unit weight (bulk density) Methods are applicable to some rocks, with some obvious modifications. Water (moisture) content ASTM D425-88(2008) Refs. 2, 12, 13 Water content as a percent of dry weight Method is applicable to rock. D1558-99(2004) D2216-10 D2974-07a D4643-80 D4959-07 Appendix A to DG-1256, Page A-2 NAME OF TEST STANDARD OR PREFERRED METHOD APPENDIX A REFERENCES PROPERTIES OR PARAMETERS DETERMINED REMARKS/SPECIAL EQUIPMENT REQUIREMENTS Relative density ASTM C127-07 Maximum and minimum density of cohesionless soils Requires vibration table. In vibration table testing, both amplitude and frequency should be adjusted to values that yield greatest density. However, treatment that produces breakage of grains should be avoided, and mechanical analyses should be performed as a check on grain breakage. Compaction ASTM D698-07 Refs. 2, 4, 14 Maximum dry unit weight
