Faster, better, and more affordable to European roads through Serbia?

Completion of the Subotica bypass

“The Epsilon branch”, i.e., the Subotica bypass, together with the “the Belgrade Bypass “, is one of the key infrastructure facilities whose construction in Serbia has been waiting for decades.

Relocation of freight traffic from the inner city has been a priority for the administration of Subotica since 1990 when work began on the construction of the “Y branch”. Endangering traffic safety due to congestion, damaged roads, water supply and sewerage network as a result of vibrations, are just some of the problems that are expected to be solved with the completion of the mentioned highway.

Due to the application of stabilization (link to stabilization on the site), modern methods that are widely used in road construction in developed parts of the world, the Subotica bypass has got its final shape in recent weeks. The ideal choice for stabilization technology is the Lafarge BeoSol hydraulic binder. Specialized for stabilizing the soil, aggregates, as well as for the cold recycling process, BeoSol binder is characterized by uniform quality with an optimal increase in strength, which reduces the possibility of cracks and rutting distress in the pavement structure, which significantly increases its durability. Roads treated in this way have been proven to be more stable, more resistant, and longer-lasting.

Beosol is currently being applied to stabilize the bedrock between the Kelebija border crossing and the Subotica South interchange (junction of the border crossing and Corridor 10); the width of the road on this route is 10.7 meters, and it is intended for heavy traffic. The works on the bypass, financed by the funds of the Republic budget, are performed by “Vojput” Subotica DOO, while the subcontractor is VD “Jugokop-Podrinje” DOO, which also performs works on the stabilization.

The performance of BeoSol binders was also confirmed during the construction of the road infrastructure of the Kovačica wind farm. At this location, 40 km of access roads and 40 windmill plateaus were built. By applying the stabilization method, a substrate ready to withstand heavy traffic load was obtained, and significantly smaller quantities of stone aggregate were used for its construction compared to the usual practice. The well-coordinated team of the company “Extra-Auto Transport” DOO performed as much as 3-4,000 m2 per day, with cost optimization concerning compared to the standard methid of filling with stone up to 50%.

In addition to the wind farm in Kovačica, the stabilization method was used on several other projects among we should mention the works on the embankments Bogojevo, Tisa – Palić, where the stabilization of the embankment crown facilitated access to all hydro-technical facilities, i.e., pumping stations and fortifications along the canal; also works on local and agricultural roads in the municipalities of Subotica, Zrenjanin, Kula, Indjija, Sombor, Šid, etc. whose stabilization was accompanied, among others, by the technical support and control of the Lafarge Geomechanics Laboratory.

Beosol has recently been used in the cold recycling process for the reconstruction of the IA-1 highway near the Indjija interchange (direction Belgrade – Novi Sad), which was performed by the company AD Sremput from Ruma. The above-mentioned method of cold recycling implies reconstruction of roads with the use of existing material from the treated road (asphalt and crushed stone), which, mixed with BeoSol hydraulic binder, provide a solid base intended for the heaviest traffic load. Advantages of this technology were among the first in our country to be recognized by the PE “Roads of Serbia”.

The importance of these modern infrastructure solutions promoted by Lafarge – stabilization and cold recycling – is recognized by the World Bank and the European Banks, which allocate funds to finance primarily projects that involve the use of existing materials and care for the conservation of natural resources. Large construction companies such as VD “Jugokop Podrinje”, “Extra-Auto Transport”, AD “Sremput”, JKP “Put”, “Inreco”, which follow world trends in road construction, have decided to implement this technology. Lafarge BFC, for its part, will maintain the leading position of a reliable partner in the construction sector of Serbia, ensuring the high quality of its products, but also the development of the offer, through new products and solutions tailored to special applications and purposes.
