Distributed Fiber Optic Strain Measurements in an Airfield Pavement
Distributed fiber optic strain sensors represent a powerful tool for gathering continuous strain data along an optical fiber within engineering structures under loads. On the other hand, pavements represent a harsh environment for optical fibers, in particular during construction process. Hence, optical fibers which are adequately protected by a robust cable sheath were used in this project for the purpose of measuring strains within a pavement. Strains were measured along the sensor cables with high spatial resolution while an aircraft was placed on the instrumented area, subjecting the pavement to static loads. The procedure was carried out in warm and cold conditions in order to study the effect of temperature conditions on the strains measured in the pavement. The measurements gave a detailed insight into the strain distribution in the loaded pavement section. The fiber optic sensors proved to be robust enough to be applied on a real construction project. Furthermore they may provide, in general, useful strain data e.g. for testing new pavement materials, assessing new design methods or investigating structural health of existing structures.
