allowable time for the Contractor and Engineer to exchange test data is as given in Table 5, unless otherwise approved. The Engineer and the Contractor shall immediately report to the other party any test result that requires production to be suspended, a payment penalty, or fails to meet the specification requirements. Use the approved communication method (e.g., email, diskette, hard copy) to submit test results to the Engineer. Table 4 Test Methods, Test Responsibility, and Minimum Certification Levels 1.

These tests are required on every sublot. 2. Optional test. To be reported as soon as results become available. 3. To be performed at the frequency shown in Table 12. 4. Additional time is allowed if cores cannot be dried to constant weight within 1 day. The Engineer will use the Department-provided software to calculate all pay adjustment factors for the lot. Sublot samples may be discarded after the Engineer and Contractor sign off on the pay adjustment summary documentation for the lot. Use the procedures described in Tex-233-F to plot the results of all quality control (QC) and quality assurance (QA) testing. Update the control charts as soon as test results for each sublot become available. Make the control charts readily accessible at the field laboratory. The Engineer may suspend production for failure to update control charts. C. QCP. Develop and follow the QCP in detail. Obtain approval from the Engineer for changes to the QCP made during the project. The Engineer may suspend operations if the Contractor fails to comply with the QCP. Submit a written QCP to the Engineer before the mandatory prepaving meeting. Receive the Engineer’s approval of the QCP before beginning production. Include the following items in the QCP. 1. Project Personnel. For project personnel, include: a list of individuals responsible for QC with authority to take corrective action and contact information for each individual listed. 2. Material Delivery and Storage. For material delivery and storage, include: the sequence of material processing, delivery, and minimum quantities to assure continuous 156
