• • • • CONSOLIDATION TESTING • Consolidation testing was performed on a selected sample of soil in general conformance with • ASTM D 2435. This test determines the magnitude and rate of consolidation of soil when it is restrained laterally and drained axially while subjected to incrementally applied controlled-stress • loading. The test results are used to estimate the magnitude and rate of settlement of the site • soils under a specific increase in effective stress. The test results are presented in this appendix. • DENSITY • We determined the density of an undisturbed soil sample in general accordance with • ASTM D 7263. The density was determined by measuring the weight of a known volume of soil and then dividing the weight of a soil sample by its known volume. The test results are • presented in this appendix. • GRAIN-SIZE TESTING • Grain-size testing was performed on selected soil samples to determine the distribution of soil • particle sizes. The testing consisted of sieve analyses (percent passing a range of U.S. Standard • sieve sizes) and percent fines determinations (percent passing the U.S. Standard No. 200 Sieve). The sieve analyses were completed in general accordance with ASTM C 117 and ASTM C 136. • The percent fines determinations were completed in general accordance with ASTM D 1 140 • (P200). The percent fines is the ratio of the dry weight of the material passing the U.S. Standard • No. 200 Sieve to the dry weight of the overall sample. Test results are presented in this • appendix. • MOISTURE CONTENT • We determined the natural moisture content of selected samples obtained from the explorations • in general accordance with ASTM D 2216. The natural moisture content is a ratio of the weight • of the water to soil in a test sample and is expressed as a percentage. The moisture contents are presented in this appendix. • • • • • • • • • • • • • • • • • G EO DESIGN? A-2 Polygon-128-01:09161 5 • 41
