STUDY ON THE MODERNIZATION OF THE AGRICULTURAL ROAD SYSTEM, CORCOVA COMMUNE, MEHEDINTI COUNTY.

The project which was proposed for implementation has, as responsable entity, the Corcova Commune, Mehedinti county, as public local authority wich owns and administrate the local roads which are proposed to be modernized. Corcova Commune is situated in the middle part of Husnita Highland, a relief unity of Getic Piedmont, which is sided by the Getic Sub-Carpathians and to the south by the Romanian plain. It detains a wide opening to the urban civilization reprezented by cities of Drobeta Turnu Severin at a 40 kilometer distance and Motru from Gorj County, at a distance of 15 kilometers, and even Craiova, but not before passing over Filiasi city, the first urban gate of Dolj County on the European roadway no. 70. The accomplishment of this project needed an applied documentation on the local realities regarding the topography, geology, geotechnics and also the traffic on the studied agricultural roads. Solving these goals requaired detailed topographical studies, applied geothenical studies and consulting GIS maps in serch of the owners neighbouring the modernized roads. After visiting the area, analyzing the geotehnical studies, measurements of the geotechnical elements, the longitudinal and transversal profiles and also observing visually the state of the expertized roads,we drew thw conclusion that the upgrading capacity of the existent road system is partially outmoded, a facts which leeds to the aparition of the faults in the form of cavities resulted from the freeze-thaw process. From the geotehnical point of view, the drillings made have intercepted some dacian formation. Dacian is the oldest geological formation which appears at surface being visible in Strehaia sector. Thus according to the plan, the actual line of the communal roads was respected, in order to avoid expropiations.The design of the curves was made in conformity with STAS 863 regulation. The red line was designed by taking into account the tickness of the proposed road system and also STAS 863 regulation and other technical normatives, providing the connection between existent declivities and respecting exceptional declivities in the curves. As a conclusion, we can state that the designed road structure will be, when the construction work is finalized, a factor in the development of the area regarding agricultural exploatation but also the wine exploatations, in the conditions in which the wine growing encountered a strong development in the last few years in this administrative zone.
