Determination of the function parameters of the concrete wear according to its multi-temporal surveys in the bridge facilities

The article considers the possibility of building a model of the concrete strength degradation if the current and previous surveys data are available. The solutions proposed permit to determine the changes of the concrete strength taking into account the value of its degradation function, they reflect concrete properties and application conditions of the object. The obtained dependences make it easy to algorithmize search for the required parameters of the concrete strength and promptly process the information in order to conduct a timely assessment of the bridge technical condition, since the concrete strength has a large influence on the load capacity of the bridge spans.
