Asphalt Pavement Structural Health Monitoring Utilizing FBG Sensors

Abstract

Pavement working state and service life assessment is really meaningful for traffic security, design evaluation and road maintenance. However, this job seems to be a mission impossible, because it is almost incredible to learn how a pavement inside works exactly when the construction is finished. As a result, in this paper, current situation of pavement-design theory and testing methods was summarized, at the same time the concept of Pavement Structural Health Monitoring (PSHM) was introduced, followed by the explanation of the FBG sensing component’s basic theory. Then, an engineering application of utilizing FBG sensors in actual pavement was introduced, the monitoring effect was shown. Conclusion is that PSHM is of great importance and utilizing FBG sensors in PSHM is effective.
