- You are given the results of index testing (i.e., Atterberg Limits; ASTM D422 and D4318) of two soil samples collected during a recent geotechnical exploration. The index test results are presented in Figure B. The first sample was taken between depths of 1.5 ft to 2.5 ft below the existing ground surface. The second sample was taken between depths of 6.5 ft to 7.5 ft below the existing ground surface. The groundwater table, at the time of the geotechnical exploration, was at a depth of 4.0 ft from the existing ground surface.
