Which items are verified on the FDOT batch ticket as part of quality control?

• A. Only batch ID.
• B. Batch design name and project phase.
• C. Batch ticket must be verified against the approved mix design, including slump, air content, temperature, and batch ID.
• D. Weather forecast and traffic control plan.

Answer: (C)

In quality control for FDOT concrete, the batch ticket serves as the link between what was produced and the approved design. The key check is to verify that the information on the ticket matches the approved mix design and that the measured properties fall within the specified limits. Specifically, you confirm that the batch ID on the ticket identifies the correct batch, that the mix design used is the approved one, and that the slump (workability), air content (durability and freeze–thaw performance), and concrete temperature meet the design requirements. This ensures the concrete being placed has the intended properties and can be traced back to the exact mix and pour. If any of these items don’t align, the material may not be acceptable and corrective actions are needed. Weather forecast and traffic control plan are important for construction planning but are not part of the batch ticket’s quality-control verification.
