Abstract: Today, the applied code and standards in France and in Europe for structural concrete are based on a prescriptive, means deemed-to-satisfy approach. Requirements related to durability are linked to exposure classes defined in the European concrete standard (EN 206). According to each exposure class, limiting values for composition of concrete are given, which can be different from one country to another depending on its experiences. The main objective of the National Project PERFDUB is to set up a methodology for justifying durability of concrete (and concrete structures) with a performance-based approach and to make it operational. To achieve this objective and despite twenty years of research on durability of concrete structures, many obstacles have still to be tackled such as: lack of suitable and practical test methods to measure durability-related properties, identification of performance thresholds resulting in targeted service life, reliability of service life models, various variabilities such as aging, spatial variability and curing effect, and commitments and responsibilities of the various stakeholders. This methodology is intended to be applied for job sites for which a specific level of quality assurance is provided. The field of research deals with new structures but is also interested in old structures in order to link pathologies where ageing is observed to the type of concrete and its sustainability features. The present article gives an overview of the technical program of PERFDUB research.
