The case of determining the serviceability of bridge beams with manufacturing defects is considered. Based on the results of visual inspection and non-destructive testing, it was found that the defects have a minor impact on the performance of the beams, and the characteristics of the building materials are high. The results of the calculations showed that the beams had almost twice the safety margin compared to the design requirements. The results of field tests of beams showed reliable anchoring of the working reinforcement, proper deformability and crack resistance of the beams. Usage of the acoustic emission method during field tests allowed to establish that the beams had no internal defects that could develop under load and reduce performance. Based on the results of the research, it was concluded that the beams manufactured with defects are suitable for use after the defects have been repaired.
