FOREWORD

This report documents the development of a novel self-powered sensor system for continuous structural health monitoring of new/reconstruction or resurfacing of asphalt and concrete pavements. The system consists of a wireless integrated circuit sensor that consumes less than 1 microwatt of power and interfaces directly with and draws its operational power from a piezoelectric transducer. Each sensor node is self-powered and capable of continuously monitoring and storing the dynamic strain levels in pavement structure. The data from all the sensors are periodically uploaded wirelessly through radio frequency (RF) transmission using a RF reader either manually operated or mounted on a moving vehicle. The integrated wireless sensor can provide many benefits to highway agencies by helping facilitate more effective pavement maintenance and rehabilitation/preservation decision making by detecting possible damage, monitoring mechanical load history, and predicting the fatigue life of the monitored pavements.
