The VTC Composite Track is a solution for in-situ concreting of composite bridges, where no formwork carriage support is needed.

VARIOKIT Composite Track VCT

The steel composite solution that takes the fast lane: Without supports and penetration of the carriageway slab and with unobstructed access from above

Thanks to the VCT Composite Track, it is possible to construct composite steel bridges with an in-situ concrete carriageway slab without the need for formwork carriage supports. The supports’ problematic block dowel effect is eliminated. In addition, there is no need to seal any penetration holes in the carriageway slab at a later date. The quality of the carriageway slab is improved and the result contributes to the longevity of the structure.
The problems that arise when using semi-finished parts are therefore also insignificant. On the construction site, you have unobstructed access from above to carry out reinforcement and concreting work. This speeds up your cycle times enormously, enabling a weekly cycle.

  • Benefits at the Planning Stage
    RE-ING-compliant

    No formwork carriage supports, no carriageway penetrations

  • Benefits at the Planning Stage
    Two Mounting Options

    Using either a welded-on tie plate, or a hole in the flange – a solution that is also listed in the RE-ING directive.

  • Benefits at the Planning Stage
    In-situ concrete

    In-situ concrete instead of prefabricated parts, resulting in a high-quality in-situ concrete carriageway slab

  • Benefits at the Construction Site
    Unobstructed access from above

    Unobstructed access from above speeds up reinforcement and concreting work, making weekly cycles possible.

  • Benefits at the Construction Site
    Steel Structure Protection

    VCT is protecting the coated steel structure and passes over bracing ribs.

  • Benefits at the Construction Site
    Flexible and Safe

    VCT is flexible with respect to its positioning and offers safe hydraulic operation using the back-step method.

Good to know at the Planning Stage

The requirements of the RE-ING directive with regard to concrete carriageway slab production using a formwork carriage that runs underneath the carriageway are met when the VCT Composite Track is deployed. As a result, no formwork carriage supports or other carriageway penetrations are required (marked red in the illustration). The result of this is a high-quality in-situ concrete carriageway slab. Another plus point: this solution eliminates the drawbacks associated with pre-cast concrete elements.

With VCT, we offer advantages in both the planning and construction of steel composite bridges. They can be built faster, with better quality and more sustainably using the in-situ concrete method. We can drive underneath and build the carriageway slab using the in-situ concrete method without having to penetrate the slab. This has not been possible before and makes our system unique in the market.
