How to make calculation with successive bisection of Arcs method for setting out a horizontal circular curve

Curves are normally found in highway and railway where it is essential to modify the direction of motion. A road or railway will generally contain a wide array of straights, circular curves and transition curves, collaboratively identified as the horizontal alignment.

In this construction video tutorial, the renowned engineer S.L.Khan will teach you how to perform calculation as well as use successive bisection of Arcs method for setting out a horizontal circular curve. This is very useful for land surveyors. It is also recognized as Versine Method.

There are top four types of linear methods of setting out curves in land surveying which range from 1. By ordinates from the Long chord 2. By Successive Bisection of Arcs. 3. By Offsets from the Tangents. 4. By Offsets from Chords Produced.

To learn the complete process, go through the following video tutorial.
