<br /> <br /> <br />APPENDIX B <br /> <br />LABORATORY TESTING <br /> <br />Laboratory tests were performed on the representative test samples to provide a basis for <br />development of design parameters. Soil materials were visually classified in the field <br />according to the Unified Soil Classification System (USCS). Selected samples were tested <br />for the following parameters: Classification and grain size determination, corrosion <br />potential, direct shear, expansion potential, in-situ moisture and density, maximum dry <br />density, and R-value Laboratory tests were performed in general accordance with the <br />American Society of Testing and Materials (ASTM) procedures and/or California Test <br />Methods (CTM). The results of our laboratory testing are presented herein. USCS <br />classifications are presented on the boring logs (Appendix A). <br /> <br />Soil samples will be discarded 30 days after the date of this report unless this office <br />receives a specific request and fee to retain the samples for a longer period. <br /> <br /> <br />80 of 100 <br />1327 S Grand Ave <br />12/12/2024
