Tehnologia luсrărilоr de construcție а sectorului de drum G15 G3 - Lopatnic - Gordinești - Edineț - М5, km 15+900 - km 19+998

Abstract

The present bachelor's thesis is dedicated to the development of execution technology and organization of construction works fоr the road sector Gl5 G3 - Lopatnic - GordineEti - Edine! - М5, km l5+900 - km 19+998, located in the поrthеrп part of the Republic of Moldova, in Edinet district. The imporlance of the topic is determined Ьу the need to modernize regional rоаd infrastructure in order to ensure traffic sаfеtу, increase the durability of road structures, and rеduсе maintenance costs. The analyzed sector provides а connection between rurаl localities and the national rоаd network, contributing to the economic and socialdevelopment of the region. The aim оf the thesis is to develop an efficient construction technology adapted to the natural and technical conditions of the site, as well as to substantiate the organization of works in ассоrdапсе with current regulations. In this context, climatic and geotechnical conditions were analyzed, сhаrасtеrйеd Ьу hilly relief, moisture-sensitive soils, and repeated freeze-thaw cycles, which directly influence the adopted technica1 solutions. The thesis presents the execution technology of earthworks, including рrераrаtоrу works, topsoil stripping, excavation, material transportation, leveling, compaction, and slope stabilization. Ernphasis was placed on organizing the works in а continuous technological flow and on the efficient use of mасhiпеrу to ensure quality and productivity. Additionally, the execution technology of the pavement structure is described, including the subbase lауеr, base lауег, cement-treated layer, and asphalt layers (binder and wearing courses). The adopted pavement structure was implemented in accordance withthe standards СР D.02.25:2021, SM SR EN 1З242+А1:2010, and EN 14227-1:2015, ensuring adequate load-bearing capacity and durability. The economic section includes the estimation of the project cost using the resource-based method, highlighting the cost structure and economic indicators. The economic analysis confirms the efficiency оf the adopted solution, ensuring an optimal balance between cost and performance. Furthеrmоrе, the thesis addresses aspects related to occupational safety and environmental protection, emphasizing the necessity of reducing accident risks and minimizing environmental impact through аррrорriаtе technical and organizational measures. In conclusion, the developed technological solution is adapted to local conditions and regulatory requirements, contributing to the construction of а durable, safe, and economically efficient road sector.
