24-8009 <br /> Page 4 <br /> <br />Laboratory Testing <br />Laboratory tests were performed on representative samples to verify the field classification of <br />the recovered samples and to evaluate the geotechnical properties of the subsurface soils and <br />bedrock. The following tests were performed: <br /> <br />• In-situ Moisture Content (ASTM D2216) and Dry Density (ASTM D7263); <br />• Maximum Dry Density and Optimum Moisture Content (ASTM D1557); <br />• Direct Shear Strength (ASTM D3080); <br />• Consolidation (ASTM D2435); <br />• Expansion Potential (ASTM D4829); <br />• Passing No. 200 Sieve (ASTM 1140); and <br />• Sulfate (Cal 417). <br /> <br />Laboratory tests for geotechnical characteristics were performed in general accordance with the <br />ASTM procedures. The results of the in-situ moisture content and density tests are shown on <br />the test pit logs (Appendix B). The results of the laboratory tests are presented in Appendix C. <br /> <br /> <br />2039 N Victoria Drive <br />#24/28/2025
