When is the final straightedge procedure performed?

• A. While paving an entire lane
• B. Before starting the paving process
• C. After an entire lane has been paved
• D. During rainfall conditions

Answer: (C)

The final straightedge procedure is performed after an entire lane has been paved because it serves as a quality control measure to ensure that the finished surface meets the specifications for smoothness and profile. This step is crucial as it allows the crew to assess the surface for any irregularities or imperfections that may affect the performance and longevity of the pavement. Conducting this procedure at this stage ensures that any necessary corrections can be made before traffic is allowed to use the newly paved surface, thus enhancing safety and durability. It is distinct from the other options, which do not align with the purpose of the final straightedge procedure.
