( � � � � I Appendix B - L.aboratory Tesdng E-4212 � Page 2. � � Particle Siu Analvsis C Grain siu analyses were oonducted on several of the shallow soil samples to determine the � siu d'utribution of the sampled soil. The information gained from this analysis allows us to provide a detailed description and classification of the in-place materials. In turn, this helps us to understand how the in-place materials will react under the proposed loading conditions. I The resulu are preunted on Plate 6, and clsssi6cation symbols are provided as part of the appropriate individual sample descriptions on the test pit logs. Atterbe� Limiu I Because of the large amounts of fines in some of the sampled soils from the �eld, we � deemed it neassary to perform an Atterberg limit test on the finer materials to determine the soils plasticity characteristics and as an aid in accurate classification of the soils. The test includes the liquid and plastic limits which were perfortned in general accordance with ASTM Test Methods D-423-66(72) and D-424-59(71), respectively. The Plastic Index, the i difference between the liquid and plastic limits, is then determined. The results of the liquid limit provide a measure of the tested soils shear strength and is analogous to the direct shear test. When coupled with the plaztic index, the resulu help us to classify the in•place � soils on the basis of these soil eharacterisdes. 'I]u result of this test is pcesented on the attached Plate 7. � I I Eerih Consultants, Inc.
