Normal crown and reverse crown roadway
Web10. Normal Crown (NC). The typical cross section on a tangent section (i.e., no superelevation). 11. Remove Adverse Crown (RC). A superelevated roadway section which is sloped across the entire traveled way in the same direction and at a rate equal to the cross slope on a tangent section. 12. Relative Longitudinal Slope.

WebDuring superelevation, the simple crowned roadway undergoes adverse crown removal. In this illustration, the adverse crown removal is the distance from End Normal Crown to Reverse Crown: Undivided Planar Roadways. The following illustration shows an undivided road as the corridor type and the cross section shape is planar. Webto the Full Super and Reverse Crown points. The Zero Crown and Normal Crown points are deleted, and the slope holds at a constant rate between the Reverse Crown points. 13) Set the Curve Overlap Adjustments for reverse curves. a) Set the Curve Type to Reverse Curve. b) Set the Adjustment Types based on the definitions of the RC_criticalTreatment
