The experience of examining small culverts of artificial structures, carried out by a number of specialized organizations, shows that on some highways of the country up to 80% of pipes have some degree of damage. This article provides data from field surveys of pipes located on the main highways of Tatarstan. Survey data is needed to identify common problems at concrete culverts in Tatarstan. Field data were also analyzed using statistical software to identify factors contributing to the degradation of concrete culverts. The article presents a method for assessing the risk of developing negative phenomena when maintaining concrete pipes. The proposed risk assessment method allows predicting and preventing the occurrence of such phenomena.
