Moisture/Density <ASTM D2216> d The filed density of the lolls-Wirs etermined by spiltbwel sampling. The sampler vas Equipped whrh 2 WI brass rings rind VMS driven manually. Settlement <MIA DE3080, The settlement camcterislics of the in-situ soil are determined by performing standard Consolidation tests on undisturbed specimens. The samples am tested in the original Sampler liner ring and the increment loads for consolIdIofl we applied for periods Of 24 hrs by means of a single counterbalance lever system. The pressure settlement Curves am shown on the attached plates. Shear Strength cASTMD3080> The shear strength of the soil is determined by performing direct sheer tests and Unconfined compression tests. The direct shear tests are performed on both undisturbed specimens and on samples Remolded to 90% of ASTIIA: D-1557-(Current Version) Method A. The samples are either Tested at in-situ moisture or are saturated to simulate the worst field condition and Sheared at a constant rate of 0.1 inches per minute. The relationship between normal Stress is shown on the attached Direct Shear Summery. The unconfined shear strength of selected undisturbed specimens and is determined in accordance with ASTM:DE-2188. These tests are performed at the existing moisture Content The results of the tests we shown on the Boring Logs. Maximum Density/Optimum MohniffecASTM D1557, • The maximum density relationship to optimum moisture was determined in accordance With ASTM:D1557-(Current Version) Method A(5 layer method). Expulsive index <AVM D4829> The exprinsive potential was determined in accordance with the 61Upansion Wax Test. Samples weremoided at 40% to 51% saturation using a specific gravity of 27. A total load of 12.63 Weis applied to the sample and allowed to consolidate for 10 mine. The sample is then saturated with distilled water and allowed to swell for a minimuni of 24hts. Soluble Sulfate CoMent cACI 3111:. 4ASTMC 1.580> The concentration of soluble sulfates In die soils is determined by measuring the optical density of a barium sulfate precipitate. The precipitate rem*, from a reaction of 'Barium chloride with water extractions from the poll lamplas. The measured optical density is correlated with a.calibratkm curve obtained from readings on precipitates Of known sulfate , tsincentradons.- Partici. Size Analysis of Soils icASTM D 422> The method covers the quendtative delanninerion of the distribution of particle sizes in soils. The distribution of particle sizes retained on the NO. 200 sieve•is determined by sieving while the distribution by a sedimentation process, using a hydrometer to secure the necessary' 2612 S Griset PI Santa Ana Ca 92704 Laboratory Testing Procedures B 2612 S Griset Pl Unit #23/17/2025
