Wood-concrete composite bridge

over the Klagenfurt expressway S 37

As part of the safety expansion of the expressway between St. Veit South and North, new bridges had to be built as well. The HASSLACHER group, together with ASFINAG, is currently implementing an innovation on the S 37 Klagenfurt expressway: One of these bridges was planned as a wood-concrete composite bridge. The wooden component is 21 m long, 1 m thick and has a width of almost 4 m. The width is made of 15 individual glued laminated timber elements, a so-called composite component according to EN 14080. It contains a total volume of 82 m³ of glued laminated timber and stores about 70 tons of CO2.

In order to be able to monitor the wood moisture, a network of sensors was woven across the entire timber structure, the data of which can be read out online at any time via a monitoring system. The HASSLACHER group's site HASSLACHER Holzbausysteme GmbH in Hermagor specializes in such special glued laminated timber components. Elements up to 52 m long and weighing up to 60 tons have already been produced, highly prefabricated and delivered from this location.
