� �� �' � �3� �r APPENDIX B W-7352 LABORATORY TESTING PROCEDURES A series of laboratory tests were performed during the course of this study to evaluate the index and geotechnical engineering properties of the subsurface soils. Descriptions of the types of tests performed are given below. Visual Classitication Samples recovered from the exploration focations were visually classified in the field during the exploration program. Representative portions of the samples were carefully packaged in water tight containers and transported to our iaboratory where the field classifications were verified or modified as required. Visual classification was done in general accordance with the United Soil Classification system. Visual soil classification includes color, relative moisture content, soil type based on grain size, and accessory soil types included in the sample. Soil classifications are presented on the exploration logs in Appendix A. Mofsture Content Delerminattons Moisture content determinations were performed on representative samples obtained from the explorations in order to aid in identification and correlation of soil types. The determinations were made in general accordance with the test procedures described in r ASTM:D-2216. The results of the tests are presented graphically on the boring logs in Appendix A. Grain Size Analysis A grain size analysis indicates the range in diameter of soil particies included in a � particular sample. Grain size analyses were performed on representative samples in general accordance with ASTM:D-422. The results of the grain size determinations for the samples were used in classification of the soiis, and are presented in this Appendix. .� 9 �r ` �:::,r . . `;': ;';- '.Tic. 9z� � ., -, f•� .;ti-'� ..-. : ;."�'Tr�.;� .ii_y,'.� r�vJi _ - S� � ��.i^.6-^',. a
