The article describes a method and results of comparative assessment of the endurance of reinforced concrete sleepers under various operating conditions. The main parameter defining the work capacity of reinforced concrete sleepers in various operating conditions is the endurance threshold of the sleeper in certain transversal cross-sections. The "typical load", a value which determines the endurance of the sleepers for a specific type of freight traffic, is essentially a function of the type of rail and number of fully-loaded heavy wagons; it is calculated on the basis of: (1) the number of loading cycles borne by the sleeper; (2) the maximum load applied during these cycles; and (3) the frequency of the repetition of these cycles, according to the traffic. This method may be applied, for instance, when assessing the endurance of reinforced concrete sleepers in the case of an increase in the axle load.
