The article provides an assessment of the effectiveness of technical solutions to strengthen the beams of spans of road bridges and indicates the advantages of using alternative reinforcement options in comparison with known solutions. The necessity of considering the collaboration of concrete and reinforcing elements on the principal planes of the webs of beams of the span is revealed. A method for determining the period of serviceability of a span is presented, as well as the dependence of this parameter on the strength characteristics of concrete beams. Calculated data are presented that allow critically assessing the effectiveness and the possibility of using various options for increasing the period of serviceability of the span of road bridges. The obtained results allow drawing conclusions about the validity and effectiveness of the proposed solutions for strengthening the span, as well as the prospects for using typical structures of previous generations in modern operating conditions.
