Unless the Engineer instructs, do not perform the initial equipment comparison <br />more than once per project. When comparing the computed dry density of one nuclear <br />gauge to a second gauge, ensure that the difference between the two computed dry <br />densities does not exceed 2 PCF [32 kg /m3] between gauges from the same manufacturer, <br />and 3 PCF [48 kg /m3] between gauges from different manufacturers. Repair or replace any <br />Quality Control gauge that does not compare favorably with the IA gauge. <br />Perform a comparison analysis between the Quality Control nuclear <br />gauge and the Verification nuclear gauge any time a nuclear gauge or repaired nuclear <br />gauge is first brought to the project. Repair and replace any Quality Control gauge that <br />does not compare favorably with the Verification gauge at any time during the remainder <br />of the project. Calibrate all Quality Control gauges annually. <br />120 - 10.1.2 Initial Production Lot: Before construction of any other Lot, <br />prepare an initial control section consisting of one full LOT in accordance with the <br />approved Quality Control Plan for the project. Notify the Engineer at least 24 hours prior to <br />production of the initial control section. Perform all QC tests required in 120 -10.1 .4. When <br />the initial Quality Control test results pass specifications, the Engineer will perform a <br />Verification test to verify compliance with the specifications. Do not begin constructing <br />another LOT until successfully completing the initial production LOT. The Engineer will <br />notify the Contractor of the initial production lot approval within three working days after <br />receiving the Contractor's Quality Control data when test results meet the following <br />conditions: <br />Quality Control tests must meet the specifications. <br />Verification test must meet the specifications. <br />Difference between Quality Control and Verification computed Dry <br />Density results shall meet the requirements of 120 -10.1 .1. <br />If Verification test result fails the density requirements of 120 -10.2, <br />correct the areas of non - compliance. The Quality Control and Verification tests will then be <br />repeated. The Engineer will reject the Contractor's Quality Control Plan after three <br />unsuccessful Verification attempts. Submit a revised Quality Control Plan to the Engineer <br />for approval. <br />120 - 10.1.3 Density over 105 %: When a QC computed dry density results in <br />a value greater than 105% of the applicable Proctor maximum dry density, the Engineer <br />will perform an Independent Verification density test within 5 feet [1.5 meters]. If the <br />Independent Verification density results in a value greater,than 105 %, the Engineer will <br />investigate the compaction methods, examine the applicable Standard Proctor Maximum <br />Density and material description. The Engineer may collect and test an Independent <br />Verification Standard Proctor Maximum Density sample for acceptance in accordance with <br />the criteria of 120 -10.2. <br />120 - 10.1.4 Quality Control Tests: <br />120 - 10.1.4.1 Standard Proctor Maximum Density Determination: <br />Determine the Quality Control standard Proctor maximum density and optimum moisture <br />�A 0 <br />March 2007 01000 -32 03- 4122.D r:.' <br />
