**7.4 Bridge deck profiles**

In a project to renew the Dinzer bridge over a canal in Friesland (The Netherlands) deck profiles were applied made from re-used EoL thermoset composite. It was one of the requirements that the profiles should resemble the original hard wood profiles by their cross-sectional dimensions (thickness 95 mm, width 245 mm) and were able to withstand heavy traffic loading.

The profiles were designed with an outside layer of virgin glass fibre reinforced polyester and a core from re-used EoL thermoset composite flakes embedded in polyester resin. Before starting production, prototypes of the profiles were mechanically tested in order to verify the mechanical loading capacity. These tests were successful and showed that the beams fulfilled the requirements for Dutch infra structural design [15]. The required profiles were produced using a resin casting method in a steel mould.

The profiles were successfully mounted on the new bridge structure of the Dinzer bridge and give off the appearance of a traditional deck with wood deck profiles, see **Figure 15**. The big advantage of these profiles made of re-used composite is that the expected service life is much longer and maintenance is lower.
