Design of Highway Alignment

Abstract

To establish the alignment of a highway of length 1km from “huzurabad to parkal” for extension of highway from two way lane to four way lane and evaluation of soil strength on the field in the form of an open transverse. The main objective of the project is to design a Highway Alignment from “Huzurabad to Parkal” for extension of highway from two way lane to four way lanes and evaluation of soil strength on field. It is an existing road already but now its road width is extended so our aim is to design the highway alignment by the following steps: 1. To carry out the detailed profile leveling which includes longitudinal sectioning and cross sectioning. 2. To fix up the formation level from the plotted longitudinal section according to prevailing gradients. 3. The earthwork has been calculated and the same is present in the graphical format. 4. Collecting the soil samples from the site and testing it in the laboratory manually. We used theodolites, chain, arrows, tape, ranging rods, tripod, levelling staff. Highway Alignment is the position or layout of centre line of the highway on the ground is called the alignment. it includes straight path, horizontal deviation and curves.
