Highway design and declaration of best possible route alternative based on the amount of earth works

Abstract

In between two points given on the contour map, two route alternatives; one obtained by zero-polygon approach and one by directly connecting the points are determined and compared according to the amount of earthworks. The route alternatives are designed according to the geometrical standards given for a 2 lane, 2nd class road on rolling terrain. Zero-polygon approach was drawn by hand on A1 paper utilizing a ruler and a compass. The drawings for the Plan, the Profiles, Superelevation and Cross Sections were done utilizing AutoCAD 2010. All the calculations required in the project were done with the use of MS Office 2010.
