Abstract
In this paper, the strain distribution and potential crack development within concrete panels for unbonded pavement overlays were investigated under truck load tests. Six full-size (183 cm x 183 cm x 7.5 cm) concrete panels instrumented with two distributed fiber optic sensors were prepared and tested to failure in the laboratory. An installation method applicable for field practice was implemented with the consideration of the fiber sensor's fragility. The distributed sensors' strain sensitivity coefficients were calibrated using a low capacity load frame. Different sensors' performance and ability to measure the strain distribution and detect cracks were compared. In the experiment, strain distributions measured from different distributed sensors were in good agreement, and can be applied to successfully locate cracks in the concrete panels.
