What is the final step in road construction?

• A. Building the crown
• B. Pouring asphalt
• C. Setting the grade stakes
• D. Compacting the surface

Answer: (A)

The final step in road construction focuses on ensuring that the road has the appropriate drainage and stability. Building the crown refers to the slight elevation at the center of the road, which facilitates water drainage toward the sides. This step is crucial as it prevents water from pooling on the surface, which can damage the roadway and create hazards for vehicles. After constructing the crown, everything else in the roadbuilding process, including paving and compaction, has been set to ensure proper performance. Hence, finishing with the crown is essential because it enhances the longevity and functionality of the road. It is the last adjustment to the road’s profile, ensuring that all earlier work supports effective drainage and the overall integrity of the roadway.
