en <br />Moisture/Density <ASTM D2216> <br />The filed dwsW of an soft was determined by split barrel sampling. <br />Equipped v fth 2 W brass rings And was driven manually. <br />Approved <br />PLOPW ISSUANC <br />Settlement <ASTM DE3000> ' aster ID: <br />The settlement cai sc lerislics of the in -situ soil are determined by SINU n <br />Consolidation tests on u rbed specimens. The are tested . .origkwl <br />Sampler liner ring and the increment loads for consolidation are applied <br />Of 24 hrs by means of a single counterbalance lever system. The pressure settlement <br />Curves are shown on tke attached plates. <br />Shear Strength <ASTM <br />The shear strength of the soil is determined by performing direct shear tests and <br />Unconfined compression tests. <br />The direct shear tests are performed on both undisturbed specimens and on samples <br />Remolded to 90% of ASTM: D-1567-(Current Version) Method A. The samples are either <br />Tested at in -situ moisture or are saturated to simulate the worst field condition and <br />Sheared at a constant rate of 0.1 inches per minute. The relationship between normal <br />Stress is shown on the attached Direct Shear Summary. <br />The unconfined shear strength of selected undisturbed specimens and is determined in <br />accordance with ASTM: DE-21W. These tests are perfonied at the existing moisture <br />Content. The results of the tests are stun on the Boring Logs. <br />Maximum DWwutyK)ptimum Mo9sftK6<ASTM DIM), <br />The ma)dmum density relationship to optimum moisture was determined in accordance <br />With AS'TWDt557-(Cunent Version) Method A(5 layer method). <br />ExWW" Index cASTM D4829> <br />The expainsive potential was determined- in accordance with the "Expansion index Test. <br />Samples pre remolded at 49% to 51% saBxition using a specific gravity of 2.7. A total load of <br />12.63 )bs-is applied to the sample and allowed to consolidate for 10 mins. The sample its then <br />saturated with distilled water and allowed to swell for a minimum of 24hrs. <br />Soluble SWfate Content <ACI 312> cASTUC 1.590:1- <br />The concerttrOW of soluble su#[ates in the soils is determined by measuring the optical <br />density of a barium sulfate precipitate. The precipitate rewft from a reaction of <br />Barium chloride with water extractions from the soil sampim The measured optical density is <br />-corm with a cailbrefon curve obtained from readings on precipitates of known suttate <br />concentrations.. <br />Particle Size Analysis of Soils <ASTM D 42;> <br />The method covers the quwAfta&& determination of the distribution of particle sizes in soils. <br />The distribution of particle sites retained on the No. 200 sieve -is determined by sieving while <br />the distribution by a sedimentation pros, using a hydrometer io secure the necessary data. <br />1602 W Brook St Unit 2 Santa Ana Ca 92703 _ . )ratory Testing Procedures 8 <br />
