WebThe general design process for a vertical curve involves the following steps: 1. Apply relevant design controls, particularly maximum grades for the highway's jurisdiction and any other vertical curve specific elements identified by the controlling agency. The profile of a road consists of road slopes, called grades, connected by parabolic vertical curves. Vertical curves are used to provide a gradual change from one road slope to another, so that vehicles may smoothly navigate grade changes as they travel. Sag vertical curves are those that have a tangent slope at the end of the curve that is higher than that of the beginning of the curve. When driving on a road, a sag curve would appear as a valley, …
