ARTICLE 120-10 (Pages 156-159) is deleted and the following substituted: 120-10 Acceptance Program. 120-10.1 General Requirements: 120-10.1.1 Initial Equipment Comparison: Before initial production, perform a comparison test using the Quality Control, Verifications and Independent Assurance gauges. Unless the Engineer instructs, do not perform the initial equipment comparison more than once per project. When comparing the computed dry density of one nuclear gauge to a second gauge, ensure that the difference between the two computed dry densities does not exceed 2 PCF [32 kg/m3] between gauges from the same manufacturer, and 3 PCF [48 kg/m3] between gauges from different manufacturers. Repair or replace any Quality Control gauge that does not compare favorably with the IA gauge. Perform a comparison analysis between the Quality Control nuclear gauge and the Verification nuclear gauge any time a nuclear gauge or repaired nuclear gauge is first brought to the project. Repair and replace any Quality Control gauge that does not compare favorably with the Verification gauge at any time during the remainder of the project. Calibrate all Quality Control gauges annually. 120-10.1.2 Initial Production Lot: Before construction of any other Lot, prepare an initial control section consisting of one full LOT in accordance with the approved Quality Control Plan for the project. Notify the Engineer at least 24 hours prior to production of the initial control section. Perform all QC tests required in 120-10.1.4. When the initial Quality Control test results pass specifications, the Engineer will perform a Verification test to verify compliance with the specifications. Do not begin constructing another LOT until successfully completing the initial production LOT. The Engineer will notify the Contractor of the initial production lot approval within three working days after receiving the Contractor's Quality Control data when test results meet the following conditions: Quality Control tests must meet the specifications. Verification test must meet the specifications. Difference between Quality Control and Verification computed Dry Density results shall meet the requirements of 120-10.1.1. If Verification test result fails the density requirements of 120-10.2, correct the areas of non-compliance. The Quality Control and Verification tests will then be repeated. The Engineer will reject the Contractor's Quality Control Plan after three unsuccessful Verification attempts. Submit a revised Quality Control Plan to the Engineer for approval. 120-10.1.3 Density over 105%: When a QC computed dry density results in a value greater than 105 % of the applicable Proctor maximum dry density, the Engineer will perform an Independent Verification density test within 5 feet [1.5 meters]. If the Independent Verification density results in a value greater than 105%, the Engineer will investigate the compaction methods, examine the applicable Standard Proctor Maximum Density and material description. The Engineer may collect and test an Independent Verification Standard Proctor Maximum Density sample for acceptance in accordance with the criteria of 120-10.2. 120-10.1.4 Quality Control Tests: 120-10.1.4.1 Standard Proctor Maximum Density Determination: Determine the Quality Control standard Proctor maximum density and optimum moisture 09/09 01000-32 03-4122.F
