By going through the following
construction video, you can learn the tips for obtaining formula toward full
super elevation of highway or road. This video is very useful for land
surveying.
Full super-elevation stands for the amount with which
the external edge of a curve located at a road or railway is grounded directly
above the inner edge. Its units range from meter/meter or feet/feet.
Another definition of super-elevation is the vertical
distance among the heights of inward and external edges of highway pavement or
railroad rails.
In order to neutralize the
consequence of centrifugal force as well as decrease the trend of vehicle to
overturn and to slide laterally outsides, pavement outer edge is elevated in
regard to inner edge. Consequently, delivering a transverse slope is called
Super elevation.
The formula is used for full super elevation = h =
Bv2/gR
Here B denotes breath of the road, v stands for speed
of vehicle, g stands for acceleration (that is 9.8 m/s2) and R stands for
radius of circular curve.
To know the detailed process, go through the following
video.
