Highways crossfall

Cross slope, cross fall or camber is a geometric feature of pavement surfaces: the transverse slope with respect to the horizon. It is a very important safety factor. Cross slope is provided to provide a drainage gradient so that water will run off the surface to a drainage system such as a street gutter or ditch. Inadequate cross slope will contribute to aquaplaning. On straight sections of normal two-lane roads, the pavement cross section is usually highest in the center and drains to … WebAdverse crossfall occurs when the road pavement slopes down from the inside of a curve to the outside of the curve, which is contrary to normal practice. Although adverse crossfall on curves should be avoided, situations arise where this may be necessary. Main Roads has adopted the following minimum radii for use with 3% adverse crossfall.
