This document summarizes the design of a proposed highway project in Bijapur, Karnataka. It includes the location details, survey methods used, components designed like pavement thickness, horizontal curves, vertical curves, and a box culvert. The design considers the longitudinal profile, cross-sections, and block contouring. Calculations are shown for pavement thickness, horizontal curve elements like radius, length, super elevation, extra widening, and sight distances. Vertical curve length is designed based on stopping and overtaking sight distances. Earthwork quantities of cutting and filling are also provided.

14. 3.Super elevation.
As the value is greater than the maximum super elevation of 0.07 limits
the value of e to 0.07 the curve is safe for full speed of 80kmph as the
ruling minimum radius is adopted, however check for transverse skid is
made
