Project SUREbridge
Hardenberg
World first in Hardenberg
The bridge at Toeslagweg across Radewijkerbeek in Hardenberg is in need of major maintenance/replacement. The municipality of Hardenberg has decided to be the first client in the Netherlands (and the world) to reconstruct the existing bridge in the Toeslagweg using the innovative SUREbridge method. The municipality of Hardenberg is carrying out the reconstruction of the bridge in a construction team including the parties Van Heteren Weg- en Waterbouw (main contractor), engineering firm Nepocon, FiberCore Europe and Strukton Civiel Noord Oost.

Preparation and planning
Monday, June 7, 2021 was the start of the work. An overall schedule of the work:
Week 0: Bridge closure. Site preparation.
Week 1: Mill surface bridge.
Week 2: Prepare deck and set anchors.
Week 3: Applying SUREbridge; Setting. Seal end faces.
Week4: Application of SUREbridge. Plug anchoring holes. Apply wearing course.
Week 5: Curing. SUREbridge application completed.
Week 6: Finish bridge and surrounding area. Completion.

Therefore, SUREbridge
The SUREbridge method offers the solution for fast, sustainable and cost-effective renovation of concrete bridges. The existing structure is strengthened and - if desired - widened by sliding a prefabricated composite panel onto it. This allows the bridge to last up to 50 years again, with minimal maintenance. By applying the method, the bridge is strengthened by a factor of 2 to 2.5, in a construction time of only 6 weeks. And because the structure does not have to be demolished, this results in savings in time, inconvenience and transport; a major environmental benefit. Costs are also saved; up to 50% compared to demolition and new construction. After applying the SUREbridge method, the bridge is once again completely future-proof!
The benefits of SUREbridge at a glance?
The technique
The SUREbridge method is an innovative concept in which the structural capacity of the bridge is increased. This is done by connecting a lightweight composite panel to the existing bridge by means of mortar. This can possibly be combined with (prestressed) carbon reinforcement on the underside of the bridge. These measures will strengthen both the compression zone and the tensile zone. It is true that the structural height increases slightly, but this increases the bearing capacity of the bridge almost by a factor of 2. The bridge can also be widened to a small extent, for example for a pedestrian or bicycle path.
Demolition of the existing structure is not necessary (sustainable) and the execution time of this method is short (minimal disruption). The reinforced structure can last another 30 to 50 years and meets today's load requirements.
Developed in a European context
SUREbridge stands for Sustainable Refurbishment of Existing Bridges. The method was developed in a partnership of 10 European countries, the United States and the European Commission. To develop SUREbridge, FiberCore Europe collaborated with Chalmers University of Technology (Sweden), University of Pisa (Italy) and AICE Consulting S.R.L. (Italy).
