Purpose. Analyze the effect of degradation rate on estimation of a remaining lifetime of Ukrainian highway bridges. Methods. Theoretical research. Results. The significant effect of degradation rate on the estimation of a remaining lifetime as the only control parameter of the Markov prediction model is proved. Originality. For the first time, the prediction error range of a remaining lifetime have been set at a constant natural rate of degradation. Practical value. The obtained results are a practical tool for managing the reliability and resource of reinforced concrete highway bridges.
