The demand on high-speed weigh-in-motion (WIM) measurement rises significantly in last decade to collect weight information for traffic managements especially after the introduction of weigh-station bypass programs such as Pre-Pass. In this study, a three-dimension glass fiber-reinforced polymer packaged fiber Bragg grating sensor (3D GFRP-FBG) is introduced to be embedded inside flexible pavements for weigh-in-motion (WIM) measurement at high speed. Sensitivity study showed that the developed sensor is very sensitive to the passing weights at high speed. Field tests also validated that the developed sensor was able to detect weights at a vehicle driving speed up to 55mph, which can be applied for WIM measurements at high speed.
