A Model for Real-Time Monitoring of Pavements

Insufficient public funds to maintain and improve the infrastructure and introduction of performance based pavement construction and maintenance contracts requires better understanding of pavement responses under dynamic loading, to carry out the correct maintenance treatment at the appropriate time in an efficient way. The current maintenance approach is a reactive technique, where the problem is addressed when the pavement distresses are observed. The objective of this study is to develop a proactive tool, using the instrumentation technique adopted in Accelerated Pavement Testing (APT) systems, to assist in decision making strategies of pavement management and enable the concept of Smart Roads. An instrumentation plan including strain gauges, pressure cells, environmental gauges and Weigh-In-Motion (WIM) scale is developed, identifying the critical parameters to be measured on in-service pavements. The paper will discuss some of the issues associated with real-time, long term monitoring of in-service pavements with the goal of providing intelligence to decision-support systems. The model will aid engineers in determining the remaining service life of pavement, assisting in applying the correct maintenance treatments at the effective time to save on major rehabilitation costs.
