Evaluating performance of carbon fiber-reinforced pavement with embedded sensors using destructive and non-destructive testing

Installation of concrete pavement at the curb travel lane bus stop is a common way to improve resistance pads environmental and petroleum deterioration in Canada. The Satisfactory condition pavements remains key consideration development infrastructure, especially countries with an aggressive environment. Innovative materials that could remarkably increase service life infrastructure are being researched developed over decades. This paper aggregates real-time comparison between performance carbon fiber-reinforced (CFRC) pad normal pad. A series wireless sensors such as temperature humidity sensors, thermocouples strain gauges were embedded both during construction. Additionally, six piezoelectric patches each Visual monitoring exhibited bus-pad remained cracked free while exhibiting some balling fibers on surface whereas several hairline cracks first 10 days Along visual using thermal imaging camera (FLIR), data was acquired regularly from bus-pads regular intervals. After 28 construction, Non-destructive tests (NDT) including Schmidt Hammer (SH), Electrical Resistivity (ER) Ultrasonic Pulse Velocity (UPV) conducted pads. When compared pads, which have electrical resistivities roughly 30 kΩ-cm, CFRC showed extremely low resistivity. hammer UPV revealed degradation Several clusters very values observed location cracks. lesser indicative scatter wave energy due presence fibers.
