[en] The knowledge and analysis of the causes of degradations is the first step in repairing existing concrete structures. The assessment is performed by using destructive and non destructive methods. These allow to detect modification of physical, chemical and/or mechanical properties of concrete: cracking, deformation, spalling, carbonation, …etc are various causes of distress, with potential irreversible consequences on concrete structure behaviour.
A description of specific methods for pavements and structural slabs is proposed; it is usually recommended to combine complementary methods for efficient diagnosis. This chapter wants to offer an overview of techniques and references that could help the user in selecting the most appropriate investigation program.
