Comparison of thermocouples surface measurements and infrared thermography for transport infrastructure thermal monitoring

International audience; This study is intended to the evaluation and improvement of instrumentation solutions for long term monitoring of new generation of transport infrastructures. A test site has been instrumented with thermocouples and an infrared thermographic system coupled with the monitoring of environmental parameters. A spatial reconstruction method is proposed. Measured data acquired on site and post-processed are analyzed through time. Finally, obtained results are commented and perspectives are proposed.
