Abstract
A study has been performed to investigate the functionality and the performance of the embedded sensors by driving a medium truck over the location of the sensors and by the numerical analysis. A total of 38 sensors have been installed to measure the stress-strain, loading configuration and environmental variation in the pavement on I-40 in New Mexico. Finite Element Model (FEM) of this instrumented section has been developed in commercial finite element software, ABAQUS. Stiffness of each layer has been determined by Falling Weight Deflectometer (FWD) test and backcalculated by ELMOD software. Surface deflections and stress-strain responses at the sensors are compared. It has been observed that the field responses closely match with the developed FEM model and thus, verify the proper functionality of the sensors. In next phase, laboratory tests on the field material are going to be conducted to further investigate the analysis results.
