Biobased FRP bridge

Schiphol Logistics Park officially put the composite biobased bridge on the logistics business park in Rozenburg (NH) into use in 2018. Schiphol Logistics Park, FiberCore Europe and TU Delft have joined forces for this special pedestrian bridge. Never before has it succeeded in producing a bridge construction in a regular building process with such sustainable products. The composition of the materials makes the bridge innovative and special.

Low maintenance, long lifespan

The bridge deck is produced as biobased as possible. Basalt fibers and biobased polyester resin are the main raw materials of the bridge deck. Advantages of fiber-reinforced plastic (also known as FRP) over traditional building materials are their high strength, the low energy requirement during construction, the low maintenance requirement and the long service life. In addition to being safe, it is also a sustainable building material. The structural properties of the material are not subject to rot or corrosion. As a result, the material is expected to last for at least a hundred years, and does not have to be replaced and minimally maintained in the meantime.

Basalt fibers

Basalt fibers are made from the basaltic rock, the volcanic coagulation rock that is created by coagulation of lava. The greatest advantage of using the basalt fiber over other technical fibers (such as fiberglass) is the strength of the material. Because the fiber is so strong, less material is needed and a lightweight bridge is created. In addition to the strength of the fiber, the material is also fully recyclable. Because it is a volcanic rock, the fiber can be melted down and extracted after the bridge’s service life, so that the material can be reused.

Bio-resin

The resin used for this bridge is partly of natural origin. Polyester resin is made from a reaction of a large number of molecules with both a carboxylic acid and an alcohol group in the molecular chain. To make this, bio-resin glycol is used that comes from vegetable glycerin.

The composite bridge at Schiphol Logistics Park was made possible in part by the supplier of the basalt fibers Mafic S.A., the supplier of the balsa BALTEK VBC by Airex AG, a member of 3A Composites, Poly Base Production B.V. for processing the balsa and Royal Haskoning DHV.
