Annotation: The general problem of durability of reinforcedconcrete elements of Ukrainian highway bridges is formulated. The life cycle model of flexible bridge elements on the basis of concrete and reinforcement corrosion process which allows predicting a resource in the form of time depending function on physicomechanical properties of concrete and reinforcement, construction type and maintenance conditions is offered. Model allows designing transport construction element with the set life cycle. Numerical examples of slab superstructures durability definition on a standard project 3.50312 on an offered model are resulted. Results confirm by statistical data of technical condition of maintained bridges on a database of AESUM bridge management system.
