M98168GE • • <br />readings during consolidation rate tests, readings during an <br />increment of load were taken regularly until the change in sample <br />height was leas than 0.001 inch over a two hour period. The <br />results of the swell-consolidation load test are summarized on <br />Figures B1 through B3, swell-consolidation tests. <br />It should be noted that the graphic presentation of consolidation <br />data is a presentation of volume change with change in axial load. <br />As a result, both expansion and consolidation can be illustrated. <br />Direct Shear Strength Tests <br />Direct shear strength properties of sleeve samples were evaluated <br />in general accordance with testing procedures defined by ASTM Test <br />Method D3080. An internal angle of friction of 25 degrees and a <br />cohesion of 250 pounds per square foot were used in our analysis <br />for the onaite soils and internal angel of friction of 25 degrees <br />and a cohesion of 1,000 pounds per square foot were used in our <br />analysis for the formational material. <br />Unconfir,ad Compressive Strength Teat <br />Unconfined compressive strength properties of sleeve samples were <br />evaluated in general accordance with testing procedures defined by <br />ASTM Test Method D2166. The testa were performed using a strain <br />controlled compression testing machine. The results of the <br />unconfined compressive strength test are presented on Figure B4. <br />Sieve Analysis Tests <br />Sieve analysis testa were conducted on selected samples of the <br />material obtained during our field study. The sieve analysis tests <br />were conducted in general accordance with ASTM Teat Method D422. <br />The results of the sieve analysis tests were not available at the <br />time of this report and will be presented when available. <br />Atterberg Limits Teats <br />Atterberg limits teats were conducted on samples obtained during <br />our field study. The Atterberg limits testa were conducted in <br />general accordance with ASTM Teet Method D43I8. The results of the <br />Atterberg limits tests were not available at the time of this <br />report and will be presented when available. <br />B2 <br />~tam6ert anD ~,s~~aciate,~ <br />COMWtTINO OtOi[CNNIGA~ tNODlttp AMD <br />uATlbAI IttTINO <br />
