APPENDIX B <br /> Laboratory Testing Program <br /> A laboratory testing program was performed for this study to evaluate the basic index and <br /> geotechnical engineering properties of the site soils. The tests performed and the procedures <br /> followed are outlined below. <br /> Soil Classification <br /> Soil samples from the explorations were visually classified in the field and then taken to our laboratory <br /> where the classifications were verified in a relatively controlled laboratory environment. Field and <br /> laboratory observations include density/consistency, moisture condition, and grain size and <br /> plasticity estimates. <br /> The classifications of selected samples were checked by laboratory tests including moisture content <br /> determinations and grain size analyses. Classifications were made in general accordance with the <br /> Unified Soil Classification (USC)System,ASTM D 2487, as presented on Figure B-1. <br /> Moisture Content <br /> Moisture contents of samples were obtained in general accordance with ASTM Test Method D 2216. <br /> The results of the moisture content tests completed on samples from the explorations are <br /> presented on the exploration logs included in Appendix A. <br /> Grain Size Analysis <br /> Grain size distribution was analyzed on representative samples in general accordance with <br /> ASTM D 422. Wet sieve analysis was used to determine the size distribution greater than the US No. <br /> 200 mesh sieve. The size distribution for particles smaller than the No. 200 mesh sieve was <br /> determined by the hydrometer method for a selected number of samples. The results of the tests are <br /> presented as curves plotting percent finer by weight versus grain size on Figures B-2 through B-5. <br /> 19106-01 <br /> NAUOZOWSUt May 29,2015 <br />
