A Lintec CC3000D containerised concrete mixing plant has helped bring Poland’s A18 highway up to modern requirements.
Owned by Częstochowa-based contractor Budpol, the Lintec CC3000D was transferred to the site in November 2021 after concluding work on the A1 highway.
The A18 was originally constructed as a single carriageway in the 1930s connecting Wroclaw with Olszyna near the Polish border with Germany. It is an important link in the European E36 road link and benefited from the construction of a northern carriageway, which began in 2004, before reconstruction of the southern carriageway started in 2020. The Lintec CC3000D travelled directly from the A1 project to the A18 project – a relatively simple task thanks to the high mobility of its design.
“It is completely built into ISO shipping containers, which allows for economic transport and simplifies installation,” explains Przemek Modrzejewski, regional sales manager at Lintec & Linnhoff. “The exceptional stability of the plant on compacted soil means there is no need to pour concrete foundations, which further reduces the cost of setup.”
The Lintec CC3000D produced 500,000 m3 of concrete in its first year of operation on the A18. The A18 will then be officially designated as an Autostrada, operating as a dual carriageway along its full 76.5 km length.
“Our Lintec CC3000D has performed well ever since it was first installed on the A1,” reveals Marcin Szymański, plant manager, Budpol. “It performed flawlessly in all seasons, and when maintenance was required we were able to do that quickly and safely, and this is the reason that we now own three Lintec plants. Budpol has supplied concrete for roads all over Poland since we started out in 1997, and we firmly believe that using innovative technology has been a key factor in our growth.”
Prior to starting work on the A18, the Lintec CC3000D worked on upgrades to the A1 highway which runs for over 550 km from Gdańsk to the Czech border near Gorzyczki. For this contract, Budpol used the Lintec CC3000D alongside a smaller Lintec CC3000B, with both machines producing over 400,000m3 during 2020 and 2021.
Although sharing the same 3 m3 mixer volume and 4.5m3 loading capacity, the Lintec CC3000D can economically double the Lintec CC3000B’s 120 m3/hr output thanks to an additional high-performance twin-shaft mixer. This extra mixer is especially useful when the varying concrete mixes required for separate road layers need to be produced simultaneously.
Capable of blending materials with particle sizes of up to 150mm in diameter, the twin-shaft design offers much greater wear resistance than conventional designs due to the thick interior abrasion-proof linings. This makes it ideal for large-volume production and improves mixing intensity, enabling the plant to yield higher loads of zero-slump concretes, RCC mixes or any type of ready-mixed concrete mixtures.
Work on the A18 highway has been completed successfully and opened in October 2023 for operations.
