Samples <br /> of the materials tested were returned to the laboratory for <br /> determination of the maximum density-optimum moisture content. <br /> The results of the field tests, attached, were also given to <br /> Mr. Gary Aksland on the testing date. <br /> The laboratory curves used to evaluate the relative degree <br /> of compaction are as follows: <br /> ASTM D-1557-70 <br /> Material Description maximum Optimum Curve <br /> and Source Dry Density Moisture Content No. <br /> Brown Silty Sandy <br /> Clay, Native, Pre- <br /> viously Reported 105. 3 pcf 19 . 4% 2 *- <br /> Tan Sandy Clayey <br /> Silt, Native 115. 0 pcf 14. 5% 3 <br />
