Note 1: Compaction test results shall be compared with the results <br />obtained during the borrow source assessment. When there are significant <br />differences, adjustments to the acceptable moisture content or density <br />ranges shall be proposed by the contractor for approval. <br />3.9.2 Moisture Content and Density Tests of In-Place Select Fill <br />Moisture content and density tests shall be performed in accordance with <br />Table 3. <br />TABLE 3 <br />MOISTURE CONTENT AND DENSITY TESTS OF IN-PLACE SELECT FILL <br />Property <br />Nuclear moisture content <br />Standard moisture content <br />Nuclear density <br />(direct transmission method) <br />Standard density <br />Test <br />Frequency Method <br />per Lift <br />10,000 square feet ASTM D 3017 <br />1 for every ASTM D 2216 <br />20 ^uclear tests <br />10,000 square feet ASTM D 2922 <br />1 for every ASTM D 1556 or <br />20 nuclear tests ASTM D 2167 <br />3.9.2.1 Test Frequencies and Locations <br />Each day that select fill is placed, a minimum of one set of standard <br />moisture content and density tests shall be performed. Nuclear density and <br />moisture content tests shall be checked at the frequencies shown in Table <br />3. Standard tests shall be performed at locations, which are as close as <br />possible to the locations of the nuclear tests being checked. <br />3.9.2.2 Nuclear Density and Moisture Content Tests <br />Nuclear density readings shall be taken in the direct transmission mode. <br />Nuclear density and moisture calibration curves shall be checked and <br />adjusted in accordance with the procedures described in ASTM D 2922 and <br />ASTM D 3017. The nuclear gauge calibration checks shall be made at the <br />beginning of a job, on each different type of material to be placed, and at <br />intervals as directed. Nuclear density and moisture content gauges shall <br />also be standardized daily in accordance with ASTM D 2922 and ASTM D 3017. <br />3.4.2.3 Test Results <br />Field moisture content and density test results shall be compared to the <br />compaction curve for the appropriate material type being tested.
