Classification <br />a.Soils were classified visually, generally according to <br />the Unified Soil Classification System. Moisture content <br />and dry density determinations were made for <br />representative, undisturbed samples.G /®*2.7 <br />b.Results of moisture-density determinations, together with <br />classifications, are shown on the Logs of Borings, in <br />Appendix B. <br />C-2. Optimum Moisture Content/Maximum Dry Density <br />The maximum dry density/optimum moisture content relationship <br />was determined for representative samples of the on-site <br />materials.The laboratory standard used was ASTM: D 1557. <br />The results are presented in Table C-1. <br />h . <br />C-3. Expansion Index <br />An Expansion Index test was performed on a representative <br />remolded sample of the on-site materials in accordance with <br />ASTM 4829.The test results are shown in Table C-2. <br />C-4. Sulfate Content <br />A water soluble sulfate content test was performed on a <br />representative sample of the on-site soils.The laboratory <br />standard used was California 417.The test result is <br />presented in Table C-3. <br />C-5. R-Value <br />An R-Value test was performed on a representative sample of <br />the near-surface on-site soils in accordance with California <br />301.The test result is presented in Table C-4. <br />C-6. Direct Shear <br />a.Direct shear tests were performed on a representative, <br />relatively undisturbed sample of the on-site materials. <br />To simulate possible adverse field conditions, the sample <br />was saturated prior to shearing. A saturating device was <br />used which permitted the sample to absorb moisture while <br />preventing volume change. The test results are presented <br />in Table C-5. <br /> ·0 .t 9 - 4 14'01 -:''Spi
