Improving the Construction of the Highway using Rocky Material Disintegrated by Blasting

摘要

In construction practice it is often possible to replace the building material, which is planned in the design phase, by the local cheaper material. In this paper analysis of the possibility of replacing the retaining structure of reinforced earth, which is envisioned in the main design of the Highway E-80: Nis - Dimitrovgrad, by embankment of disintegrated rocky material, is presented. This material is obtained by blasting the rock mass near this location. Recommendations for changing of the main design were given based on the results of the computational slope stability analysis which was performed by the limit equilibrium method, according to Spencer's solution. Due to this change the organization of construction works is significantly improved.
