DIAGNOSIS AND MONITORING OF CONCRETE BRIDGES DAMAGED BY A.A.R. IN NORTHERN FRANCE

After a brief description of the pathology found in these structures and a rapid survey of the parameters of influence of the alkali- aggregate reaction (concrete formulation, environmental conditions, etc.), the article focuses on 3 methods applied to investigate the behaviour of bridges: monitoring of map-cracking development, monitoring of the evolution of global deformation by infrared distancemeter, and expansion tests on drilled cores. A first judgment is made of the utility of each of these methods. (A) For the covering abstract see IRRD 871351.
