<br />.... <br /> <br />. <br /> <br />,.., <br /> <br />,., <br /> <br />content by sampling and testing the material in accordance with the specified test method <br />listed in 120-10.2. <br />120-10.1.4.2 Density Testing Requirements: Ensure compliance to <br />the requirements of 120-10.2 by Nuclear Density testing in accordance with FM 1-T 238. <br />Determine the in-place moisture content for each density test. Use Florida Method <br />FM 1-T 238, FM 5-507 (Determination of Moisture Content by Means of a Calcium Carbide <br />Gas Pressure Moisture Tester), or ASTM D 4643 (Laboratory Determination of Moisture <br />Content of Granular Soils By Use of a Microwave Oven) for moisture determination. <br />120-10.1.4.3 Soil Classification: Perform soil classification tests on <br />the sample collected in 120-10.1.4.1, in accordance with AASHTO T-88. Classify soils in <br />accordance with AASHTO M-145 in order to determine compliance with embankment <br />utilization requirements. Unless required by the Engineer, do not test or classify materials <br />for stabilized subgrade or base. <br />120-10.1.5 Department Verification: The Engineer will conduct a Verification <br />testIs) in order to accept all materials and work associated with 120-10.1.4. The Engineer <br />will verify the Quality Control results if they meet the Verification Comparison Criteria, <br />otherwise the Engineer will implement Resolution procedures. <br />The Engineer will select test locations, including Station, Offset, and <br />Lift, using a Random Number generator based on the Lots under consideration. Each <br />Verification test evaluates all work represented by the Quality Control testing completed in <br />those LOTs. <br />In addition to the Verification testing, the Engineer may perform <br />additional Independent Verification (IV) testing. The Engineer will evaluate and act upon the <br />IV test results in the same manner as Verification test results. <br />When the project requires less than four Quality Control tests per <br />material type, the Engineer reserves the right to accept the materials and work through <br />visual inspection. <br />120-10.1.6 Reduced Testing Frequency: When no Resolution testing is <br />required for 12 consecutive verified LOTs, or if required, the QC test data was upheld, <br />reduce the QC density testing to one test every two LOTs by identifying the substantiating <br />tests in the Density Log Book and notifying the Engineer in writing prior to starting reduced <br />frequency of testing. Generate random numbers based on the two LOTs under <br />consideration. When Quality Control test frequency is reduced to one every two LOTs, <br />obtain the Engineer's approval to place more than one LOT over an untested LOT. Assure <br />similar compaction efforts for the untested LOTs. If the Verification test fails, and Quality <br />Control test data is not upheld by Resolution testing the Quality Control testing will revert <br />to the original frequency of one Quality Control test per LOT. The results of the <br />Independent Verification testing will not affect the frequency of the Quality Control testing. <br />120-10.2 Acceptance Criteria: Obtain a minimum Quality Control (QC) density of <br />100% of the standard Proctor maximum density as determined by AASHTO T 99, <br />Method C, with the following exceptions: 1) embankment constructed by the hydraulic <br />method as specified in 120-8.3; 2) material placed outside the standard minimum slope as <br />specified in 120-8.2.4; and 3) other areas specifically excluded herein. <br />120-10.3 Additional Requirements: <br />120-10.3.1 Frequency: Conduct QC sampling and testing at a minimum <br />frequency listed in the table below. The Engineer will perform Verification sampling and <br />tests at a minimum frequency listed in the table below. <br /> <br />. <br /> <br />,., <br /> <br />. <br /> <br />f'1 <br />. <br /> <br />.., <br />. <br /> <br />., <br />. <br /> <br />'"1 <br />. <br /> <br />.., <br />. <br /> <br />.., <br />. <br /> <br />rt <br />. <br /> <br />I""l <br /> <br />. <br /> <br />. <br /> <br />...., <br />. <br /> <br />,.., <br />. <br /> <br />r'l <br />. <br /> <br />.., <br />. <br /> <br />f""l <br /> <br />... <br /> <br />., <br /> <br />. <br /> <br />r-, <br /> <br />09/09 <br /> <br />01000-33 <br /> <br />03-4122.F <br /> <br />. <br />
