The document defines and discusses key elements of road cross sections, including the pavement surface, unevenness, cross slope or camber, carriage way, traffic separators, kerbs, road margin, and right of ways. It notes that camber is usually provided on straight roads by raising the center of the carriage way to form a crown for drainage, with a cross slope ratio of 1 vertical to n horizontal commonly used. An adequate but not too steep slope of 1.7-2% is sufficient for concrete or asphalt surfaces.
