<br />APPENDIX
<br />APPENDIX B
<br />LABORATORY TESTING
<br />Laboratory tests were performed in accordance with generally accepted test methods of the "American
<br />Society for Testing and Materials (ASTM)", or other suggested procedures. Selected samples were tested
<br />for direct shear strength, consolidation and expansion characteristics, corrosivity, in -place dry density
<br />and moisture content. The results of the laboratory tests are summarized in Figures B 1 through B9.
<br />The in -place dry density and moisture content of the samples tested are presented on the boring logs,
