� APPENDIX B LABORATORY TESTI NG General Soil samples obtained from the explorations were transported to our laboratory and examined to confirm or modify fieid classifications, as well as to evaluate engineering and index properties of the soil samples. Representative samples were selected for laboratory testing consisting of moisture content and grain size distribution determination. The tests were perFormed in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other applicable procedures. Soil Classification All soil samples obtained from the explorations were visually classified in the field and/or in our laboratory using a system based on the Unified Soil Classification System (USCS) and ASTM classification methods. ASTM test method D 2488 was used to visually classify the soil samples, while ASTM D 2487 was used to classify the soils based on laboratory tests results. These classification procedures are incorporated in the exploration logs shown in Figures A-2 through A-27, in Appendix A. Moisture Content Testing Moisture content tests were completed in general accordance with ASTM D 2216 for representative samples obtained from the explorations. The results of these tests are presented on the expioration logs in Appendix A at the depths at which the samples were obtained. Grain Size Analyses Grain size analyses using sieves and hydrometers were perFormed on selected samples in general accordance with ASTM D 422 to determine the sample grain size distribution. The wet sieve analysis method was used to determine the percentage of soil greater than the U.S. No. 200 mesh sieve. A hydrometer test was completed on two samples (TP-12 and TP-17) to determine the percentage of soil passing the U.S. No. 200 sieve. The results of the sieve analyses were plotted, classified in general accordance with the USCS,and are presented in Figures B-1 through B-6. �iEOENGINEER� October24,2014 PageB-1 Fle No.0482-027-02
