Cur Job 81-20-00 Page A-4 <br />TESTING <br />I'{oisture-Densit}'. Field moisture ccntent and in-p1ace <br />density were determined for each drive sarnple of undisturbed soil <br />material obtained. The field noisture content is determined <br />according to ASTM Test Method D2216-66 by obtaining one-ha1f the <br />moisture sample from each end of the drive sleeve. The in-place <br />dry density of the sample is deternined by using the wet weight <br />of the entire sample. <br />At the same time the field moisture content and in-place <br />density are determined, the soil material at each end of the sleeve <br />are classified according to the Unified Soil Classification S1'stern, <br />and for cohesirre soi1s, the shearing resistance is estimated <br />using a hand-operated pocket penetrometer device. The results <br />of the field moisture content and in-p1ace density determinations <br />are presented on the right-hand column of Plates A-1.1 through <br />A-1.4 - Log of Drill Ho1e. The results of the visual classifi- <br />cation and pocket penetrometer tests are used in finalizing the <br />field dri11 hole 1ogs. <br />Compaction Tests. A bulk sample representati\re of the <br />surficial, oD-site soil was tested to determine the maximum dry <br />density and optimum noisture content. These compactive character- <br />istics were determined according to ASTM Test Method D1557'70. <br />The results are summarized on Plate A-3 - Compaction Test Data.
