The plant is being used to supply materials for a 14km stretch of Poland’s S7 expressway project and will produce 250,000m3 of concrete for the new road link.
This plant was selected for the project due to its high concrete production capacity of 240m3/hr.
The expressway is important as it forms part of the Trans-European Transport Network (TEN-T) within the Baltic-Adriatic Corridor. The 720km-long S7 expressway runs from near Gdansk on the Baltic Sea coast to Chyzne, just before the Slovakian border. The road is also part of European route E77, which links a number of important towns and cities on its way from Pskov in Russia to the Hungarian capital, Budapest.
Most of the expressway will be built by upgrading the existing National Road 7 (DK 7), doubling the number of lanes and adding new interchanges, bridges and overpasses.
With two-thirds or more of the project now complete, work on the remaining five sections is now underway. On a 14km stretch of one of these expressways between Napierki and Płońsk, the Lintec plant is being used by Janikowo-based contractor Trans-Am Maciej Antkowiak.
Connecting Napierki and Mława in the province of Mazowieckie, approximately 130km north of Warsaw, this northern slice of the new section will host two of its nine junctions. Like the other 57km, it will comprise two 3.5m-wide lanes, a 2.5m-wide hard shoulder and a 0.75m-wide soft shoulder on either side of a 12m central divider. There is also the option to add a third lane depending on future requirements.
The two twin shaft mixers in the Lintec CCP3000D concrete batching plant allow for independent production. They can produce different batches of concrete at the same time using both the first mixer in the upper layer and the second mixer in the bottom layer.
The contractor also appreciated the mobility of the plant due to its modular structure that is built into ISO shipping containers for economical transportation as well as easy installation and dismantling.
The EU’s Cohesion Fund has contributed over half of the €450 million investment required for the construction of the 71km section. Apart from a 25km section running south from Kraków, the entire S7 project is scheduled for completion by 2026. The Lintec CCP3000D will remain in service near Mława until late 2022.
