Previously great attention has been given for the quality of track superstructure to improve therngeneral technology of the railway scheme. But frequent research on track supporting materialsrnshow a good result which improves the general overall performance; safe ride with smoothrnwheel-rail steering ,high speed, minimum initial cost and accepted tolerance with respect tornvoice, and vibration .Generally positive whole life cycle analysis are the basic concern on thernrailway technology. And such a good quality in strength and life cycle of railway trackrncomponent contribute high for the performance of the general track structure in different angles.rnIn Ethiopia, on the new projects of railway; ballast as a basic constitute and determinant part ofrnthe selected ballistic electrified track; many researches not yet done in maximizing its efficiencyrnon the coming project.rnAnd General selection of uneconomical quarry sites which is not located on the logicalrnacceptable radius of the project , stated as the core problem of the thesis and their respected costrnvariation they experienced on the project studied in depth.rnIn order to elaborate it , case study is selected on recently undergoing Ethio -Djibouti railwayrnproject of section Sebeta - Meiso ; two uneconomical quarry sites (Adama-Awash) selected byrnthe contractor which are located out of the logical economic radius pointed down.rnThe aim of this thesis is to access and study many different aspects which affect the generalrnselection of the ballast materials; exploring additional quarry site in between Adama and Awashrnquarry sites and came with solution with minor blending with neighboring quarry to meet thernrequired standard engineering properties.rnFinally this thesis finds alternative and reasonable solution of quarry configuration (Adama-rnArole-Awash) after detailed economic evaluation and acceptable laboratorial results whichrnexperience high cost minimization than currently selected quarry site configuration (Adama-rnAwash) by the contractor.
