The general problem of bridge reinforced concrete elements durability is formulated. The research problem is formulated. The model of estimation of bridge reinforced concrete elements resource on a design stage is offered. It enables us to predict the resource as a function of time in dependence on physical-and-mechanical properties of concrete and reinforcement, type of structures, and operation conditions. Some numerical examples of durability determination according to the model offered are presented. The results of research are analyzed. Open questions are brought for discussion.
