Abstract

Based on the data of field surveys, the results of assessing the state of reinforced concrete span structures of bridges and characteristic defects that occur in the structure during operation are presented. An analysis of the results of inspections and periodic inspections responsible for the operation of artificial structures shows that a significant part of reinforced concrete spans has various types of defects and damage to load-bearing structures. Studies show that defects have a significant impact on the operational properties of reinforced concrete spans, leading both to a limitation of the speed regime of train movements and to the emergence of factors negatively affecting uptime
