Randy: <br />Transmitted herewith are the results of six triaxial shear <br />tests performed on samples delivered to our office by your <br />organization. The triaxial shear tests are presented in the <br />form of a Mohr envelope as shown on the attached sheets. <br />In obtaining the friction angle, the material was densified <br />to unit weights of between 100 and 103 pounds per cubic foot. <br />The materials were saturated by back pressure techniques prior <br />to performing the tests. It will be noted that friction angles <br />of 2w.o and 25 degrees were obtained for these materials, <br />r=_spectively. <br />Plaase advise us if we can be of further assiscar.ce to <br />~'ou. <br />Sincere_~, <br />R^LLI`.S. 330G:~,AND GUND;ELL, INC. <br />._~~ <br />kalph L.
