M . r'l . j"I Department will select test locations, including Stations, Offsets, and Lifts using a Random Number generator, based on a set LOTs under consideration. If the Verification test results are not deficient as defined in 200-7.3.1.2, the QC test data will be considered verified. If the Verification test results are deficient, the requirements of 200-7.4.3 will apply in affected LOTs. Provide traffic control, coring/boring equipment, and an operator for the coring/boring equipment. Traffic control is to be provided in accordance with the standard maintenance of traffic requirements of the Contract. 200-7.4 Verification Comparison Criteria and Resolution Procedures: 200-7.4.1 Modified Proctor Maximum Density: The Engineer will verify the Quality Control results of the 16 consecutive LOTs if the Verification test result compares within 4.5 PCF [72 kg/m3] of the QC result for the corresponding LOTs. Otherwise, the Engineer will collect the Resolution split sample corresponding to the Verification sample tested. The State Materials Office or an AASHTO accredited laboratory designated by the State Materials Office will perform Resolution testing. The material will be sampled and tested in accordance with FM 1-T 180, Method D. The Engineer will compare the Resolution Test results with the Quality Control test results. If the Resolution Test result is within 4.5 PCF [72 kg/m3] of the corresponding Quality Control test result, the Engineer will use the Quality Control test results for material acceptance purposes for each corresponding set of eight LOTs. If the Resolution test result is not within 4.5 PCF [72 kg/m3] of the corresponding Quality Control test, the Engineer will collect the remaining Verification split sample for testing. Verification Test results will be used for material acceptance purposes for the 16 LOTs in question. 200-7.4.2 Density: When a Verification or Independent Verification density test does not meet the requirements of 200-7.2.1 (Acceptance Criteria), retest the LOT at a. site within a 5 feet (1.5 meter) radius of the Verification test location and observe the following: 1. If the Quality Control retest meets the Acceptance Criteria and compares favorably with the Verification or Independent Verification test, the Engineer will accept the four LOTs in question. 2. If the Quality Control retest does not meet the Acceptance Criteria and compares favorably with the Verification or Independent Verification test, rework and retest the material in that LOT. The Engineer will re-verify the four LOTs in question. 3. If the Quality Control retest and the Verification or Independent Verification test do not compare favorably, complete a new equipment-comparison analysis as defined in 120-10.1.1. Once acceptable comparison is achieved, retest the four LOTs. The Engineer will perform new verification testing. Acceptance testing will not begin on a new LOT until the Contractor has a gauge that meets the comparison requirements. 200-7.4.3 Thickness and Surface Testing Requirements: When a Verification or Independent Verification density test does not meet the requirements of 200-7.3.1.2 (Acceptance Criteria), perform a QC re-test within 5 feet [1.5 m] of the Verification test site in each affected LOT. If the QC re-test meets the requirements, the LOT will be accepted using QC test results. If the QC re-test confirms deficient thickness or surface irregularity, the Contractor will rework and re-test that LOT by scarifying and adding additional base material. The Department will re-verify the group of those LOTs. As an exception, if authorized by the Engineer, such areas may be left in place without correction and with no payment. r'l . 11 . . .., . 1"1 . 1 . ,.., .
