Abstract
The paper presents the process of assessing the technical condition of reinforced concrete supports of existing technological overpasses, gives their characteristics, shows the defects found in the process of assessing the technical condition. The article describes the monitoring of concrete strength by the non-destructive method of elastic rebound using the Digi Shmidt 2000 device and the determination of the thickness of the concrete cover and the location of reinforcement by the magnetic method using the Profometer-5S device. We determined the layout of the working reinforcement in the reinforced concrete supports of the overpasses’ sections. We present the results of verification calculations of the structures of the technological overpasses, taking into account the revealed defects and damages, the strength of materials and the specified actual loads. We give recommendations for improving the performance of the concrete of the reinforced concrete supports of the overpasses.
