Results of the tests conducted on bedrock samples are <br />summarized in the following sections. <br />4.3.1 Index Tests <br />Index tests conducted on selected rock core samples included sieve analyses and <br />Atterberg Limits. Results of laboratory index tests on rock core samples are summarized <br />in Table 4.3 and additional information is presented in Appendix E. <br />GEI Consultants, Inc. 4-2 <br /> <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br />Cf <br /> <br />r <br />~~ <br /> <br /> <br /> <br />1 <br />98•~SSm unwed <br />
