What is the first step when using a manual cross slope?

The first step when using a manual cross slope involves placing a simple level on the pavement. This action is critical because it allows the operator to assess the existing grade of the surface and determine if any adjustments are required to achieve the desired cross slope. Using a level ensures that the slope is uniform and meets design specifications, enabling proper water drainage and enhancing the longevity of the pavement.

Once the level is placed on the pavement, it provides a visual reference which indicates whether the surface is flat, sloped, or in need of correction. This foundational assessment is essential before proceeding with any measurements or adjustments, as any subsequent steps depend on understanding the current state of the pavement. It sets the groundwork for marking the slope area, measuring heights, or adjusting pavement height as necessary later in the process.
