Upgrading cobblestone road to paved road (behind Wolkite university dormitory)

Abstract

Highway transportation system is one of the most commonly used modes of transportation system in Ethiopia. The road project we are going to design, as a partial fulfillment of B.Sc. Degree in Civil Engineering, and the project is about upgrading cobble-stone road to paved road. The design includes; geometric design, pavement design (flexible pavement) and drainage design of a selected road.We intensively depend on the AACRA design manual for the design of all Highways are of major importance in the development of a country as they play a vital role in facilitating the movement of people and goods from place to place in the most comfortable, safe and desirable way. And we have also roughly referred ERA design manual & other related scriptures on highway for some data that are vague on AACRA.The document includes three design: the first is geometric design; to design geometry of a given road we intensively depends on AACRA geometric design manual, the second part is about pavement design; to design pavement of a given road we intensively depends on AACRA pavement design manual, finally we design highway drainage; to design highway drainage of a given road we intensively depends on AACRA drainage design manual. So after finishing the project we will submit the report to Civil engineering Department of Wolkite University and the site should be upgraded to flexible pavement according to our design and we recommended that civil 3D software is much better for pavement design so we suggest the software civil 3D.
