APPENDIX B LABORATbRY TESTS A laboratory test program was developed to establish the basic index and engineering properties of the soil samples obtained in the field. The program was oriented primarily towards determining the variations in moisture content, classification, grain size analysis and Atterberg Limit determinations of the soils as an indirect indication of the potential variation in engineering properties. The laboratory testing procedures are outlined below. IVisual Classification IAll samples were visually re-classified in our laboratory and the field logs verified and modified as required, The Unified ISoil Classification System presented in Figure B-1 was utilized as the basis for visual examination and for classification of I� selected sample� for which specific laboratory tests were performed. �• The degree of moisture in the sample (whether it was dry, moist � or wet), the approximate percentage of fi.ies in the sample and the relative plasticity of the fines were particularly noted. + Moisture Content � Moisture contents were performed on all samples in general accordance with ASTTi D2216-71 as soon as possible folloming Itheir arrival in our Seattle laboratory. Natural water contents were determined for the purpose of: (1) Identification and � correlation of soils, ,and (2) Providin� basic engineering properties. The water contents are presented on the test pit logs of this � appendix and on other figures where appropriate. � r I
