Part of E-80 highway that passes through Serbia (from the city of Nis to the administrative border Merdare) is 77 km long. The highway is divided into two sections: the first from Nis to Plocnik (39.4 km long) and the second from Plocnik to the administrative border with Kosovo. The route is designed through a typical plain and hilly terrain in which different geological units are dominant: crystalline schists, neogene sediments of foothills and quaternary sediments in the valley of the Toplica River and its tributaries. Compared to the total length of the first section, about 20 % is covered by appropriate structures (tunnels, bridges, overpasses), while on the rest of the section, the construction of numerous cuts is planned, and almost 45% of the route passes through alluvial relief of the Toplica River where the embankments of variable height will be built. The results of performed investigation works were used for general geotechnical rejonization of the terrain in the wider area of the highway route, according to the previously performed engineering-geological zoning of the terrain. Geotechnical rejonization is performed based on numerous factors which are generally divided into three basic categories: „factors of the past“, „factors of the present“ and „factors of the future“. In this way, the following were identified: A - „favorable“, B - „conditionaly favorable“ and C - „unfavorable“ sections, which are related to the complexity of the construction of planned structures on the highway route (excavations, cuts, filling, draining etc.).
