, 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 of soil Method for earth-rock mixtures is given in Ref. 15. D1557-09 D4253-00(2006) D4254-00(2006) D5080-08 SOILS—CONSOLIDATION AND PERMEABILITY Consolidation ASTM D2435-04 Refs. 2, 4, 14 One-dimensional compressibility, permeability of cohesive soil D4186-06 Permeability ASTM D2434-68(2006) Refs. 2, 4, 16 Permeability Suitable for remolded or compacted soils. For natural, in situ soils, field test should be used. D5084-10 SOILS—PHYSICAL AND CHEMICAL PROPERTIES Mineralogy Refs. 17, 18, 19 Identification of minerals Applicable to rock. Requires x-ray diffraction apparatus. Differential thermal analysis apparatus may also be used. Organinc Content ASTM D2974-07 Ref. 20 Organic and inorganic carbon content as percent of dry weight Dry combustion methods (ASTM D2974) are acceptable, but where organic matter content is critical, data so obtained should be verified by wet combustion tests. Soluble salts ASTM D4542-07 Ref. 21 Concentration of soluble salts in soil pore water Erodibility tests ASTM D5852-00(2007) Pinhole test ASTM D4221-99(2005) Refs. 22, 23 Significant in evaluation of potential erosion or piping D4647-06e1 Crumb test ATSM D6572-06 Qualitative indication of the natural dispersive characteristics of clayey soils Appendix A to DG-1256, Page A-3 NAME OF TEST STANDARD OR PREFERRED METHOD APPENDIX A REFERENCES PROPERTIES OR PARAMETERS DETERMINED REMARKS/SPECIAL EQUIPMENT REQUIREMENTS Cylinder dispersion Ref. 1 SOILS—SHEAR STRENGTH AND DEFORMABILITY Unconfined compression ASTM D2166-06 Ref. 1 Strength of cohesive soil in uniaxial compression Direct shear, consolidated- drained ASTM D3080-04 Ref. 4 Cohesion and angle of internal friction under drained conditions Triaxial compression, unconsolidated- undrained ASTM D2850-03a(2007) Refs. 2, 4, 25 Shear strength
