Why is it important to set utility structures to an appropriate grade prior to paving?

• A. To reduce costs
• B. To match top elevation of pavement
• C. To improve appearance
• D. To comply with regulations

Answer: (B)

Setting utility structures to the appropriate grade prior to paving is crucial for several reasons, with matching the top elevation of the pavement being the primary concern. When utility structures, such as manholes, catch basins, and valve boxes, are raised to the correct elevation, it ensures a smooth, even surface for the roadway or pavement. This not only enhances the functionality of the pavement but also minimizes the risk of creating bumps or depressions that could affect vehicle traffic, safety, and overall ride quality.

Additionally, setting these structures correctly helps prevent water from pooling at the edges, which can lead to drainage issues and potential damage to both the utility structures and the surrounding pavement over time. Proper elevation also facilitates maintenance access and ensures that the utility structures are not a hazard for vehicles and pedestrians. Ultimately, achieving the correct top elevation is integral to providing a durable and well-performing paved surface.
