A-3 <br />moisture content and density of the soils, to aid in <br />classifying the soils, and to help correlate the direct <br />shear test data. The results of the moisture and den- <br />sity tests are presented on the left side of the boring <br />logs on Plates A-lA and A -IB. <br />GRAIN -SIZE DETERMINATIONS <br />Gradation tests were performed on representa- <br />tive samples to aid in classifying the soils and to help <br />correlate the strength test data. The results of the <br />gradation tests are shown on Platea A -4A through A -4C, <br />Gradation Curves. <br />ATTERBURG LIMITS <br />Atterburg limits determinations were made or, <br />two soil samples. These tests provide information re- <br />garding the plasticity of clay and silty soils. The <br />results of the Atterburg limits tests are tabulated on <br />the following page. <br />�>AMESi L' MOOR E_ <br />
