SECTION 905: QUALITY ASSURANCE FOR MINOR PAVING 905.1 DESCRIPTION The Department will sample and test Materials for Acceptance u nless otherwise specified in the Contract. The Department will provide these test result s to the Contractor within two
2.Working Days after sampli ng. Any additional testing by the Department will be provided to the Contractor upon written request. Department testing is not for Quality Control. 905.1.1 Department Sampling and Testing for Acceptance The Department will sample and test in accordance with Section 906, “Minimum Testing Requirements” or at a lesser sublot size for Assurance purposes as determined by the Project Manager before production of Material begins. If Material appe ars defective, or if the Project Manager determines that a change in the process or product has occurred, additional sampling and testing may occur. When the Department performs a dditional informational sampling and testing, the results will be used only to determin e if corrective actions need to be taken by the Contractor. 905.1.2 Independent Assurance Testing TTCP certified independent personnel will perform Independent Assurance testing on split samples from Quality Control and Assurance programs to en sure that the Contractor and Department field personnel are using correct and accurate proce dures and the proper Equipment. These personnel will not have direct responsibility for Quality Control or Assurance testing. Independent A ssurance Test results will not be used for Acceptance. 905.1.3 Evaluation of Materials for Acceptance 905.1.3.1 Acceptance The Department will Accept the constructed product based on in spection and on Laboratory testing for conformance with the Contract. The Depa rtment will test samples of HMA/WMA taken from the Roadway before compaction and on cut pav ement samples (cores). The Department will Acc ept the constructed product ba sed on the following criteria:
1.Air voids as determined from Laboratory-compacted specimens in accordance with AASHTO T 166 and AASHTO T 209;
2.Asphalt content as determined by the tank strap method or plant asphalt metering system defined in the Contractor’s Quality Control Plan (binder ignition oven calibration samples will not be required);
3.Final thickness of the compacted Material as measured from c ores in accordance with ASTM D 3549; and
4.Density of the compacted Roadbed as determined in accordance w i t h AASHTO T 310, Standard Method of Test for In-Place Density and Moisture Content of Soil-Aggregate by Nuclear Methods (Shallow Depth). The Contractor shall provide cores from three (3) locations designated by the Project Manager for correlation with the Nuclear Densometer. Department representatives, certified in the relevant test pro cedures by the State Materials Bureau through TTCP, will perform Acceptance testing in accordance with AASHTO or Department methods, using the test methods and modifications in the current TTCP Manual. 905.1.3.2 Acceptance Lots and Pay Factor Determination The Department will Accept density based on the average of all density tests per Project, taken at a minimum of ten (10) density tests per 5,000 tons, an d will Accept air voids and asphalt content based on a minimum of three (3) tests per 5,000 tons. The Department will determine pay factors in accordance with T able 905.1.3.2:1, “Price Adjustments for Density,” Table 905.1.3.2:2, “Price Adjustments f o r A i r V o i d s , ” Table 905.1.3.2:3, “Price Adjustments for Asphalt Content,” and Table 905.1.3.2:4, “Price Adjustment for Thickness.” The Department will obtain the TVs for asphalt content and air voids from the approved JMF and will determine payment for each Acceptance lot by multiplying the Bid Item Unit Price by the average of the pay f actors per lot and multiplying the result by the total lot area.

The Contractor shall take corrective action if specified in Ta ble 905.1.3.2:4, “Price Adjustment for Thickness.” Co rrective action includes removal and replacement of the unacceptable Material, overlay of the unacceptable Material, or other corrective actions approved by the Project Manager. Thin or feathered edge surfac e patching is not Acceptable.
