The 33.0 m long reinforced concrete bridge beams of the overpass superstructure after vehicular impacts were taken as a research object.
The overpass consists of 14 beams, six of which were repaired by restoring the widened lower part with EMACO FAST TIXO, manufactured by BASF.
The remaining 8 beams were completely dismantled and replaced with new ones. The new beams have been fully tested for the perception of vehicular loads. The fully reconstructed span structure showed compliance with the design loads of A14, NK-120 and NK-180 based on test results.
Keywords: overpass, superstructure, detailed survey, beam damage, beam testing, FEM
