How can cross slopes be created during paving?

Creating cross slopes during paving refers to the intentional tilt of the surface to facilitate drainage. The correct answer highlights that this can be achieved either manually or with a smart level, indicating a versatility in the methods used for establishing the desired slope.

When using manual techniques, workers can adjust their paving technique and angle to create the slope needed. A smart level can enhance precision, making it easier to achieve consistent slopes across the paved area. This method allows for adjustments in real-time, ensuring the slope meets specifications effectively.

In contrast, relying only on mechanical tools may not provide the same level of control and adaptability needed for varying surface conditions. Adding extra asphalt could lead to uneven surfaces rather than a defined slope; this approach is often impractical and does not ensure the necessary cross slope for proper drainage. Using only digital levels also limits the methods of creating slopes to one technology, whereas utilizing both manual methods and smart levels allows for a broader range of techniques, accommodating different paving scenarios and ensuring better outcomes.
