Recently, significant attention has been devoted to the utilization of new sensing technologies for pavement maintenance and preservation systems. This study presents a new approach for the continuous health monitoring of asphalt concrete pavements based on piezoelectric self-powered sensing technology. The beauty of this technology is that the signal sensed by the piezoelectric transducers from traffic loading can be used both for empowering the self-powered sensors and damage diagnosis. Numerical and experimental studies were carried out to evaluate the damage detection performance of the proposed self-sustained sensing system. A three-dimensional finite element analysis was performed to obtain the pavement responses under moving tire loading. Damage was introduced as bottom-up fatigue cracks at the bottom of the asphalt layer. Thereafter, features extracted from the dynamic strain data for a …
