Sensor Network for Pavement Performance Monitoring

Preventive maintenance of roadway pavements requires reliable estimates of pavement deterioration. Existing successful measurements of pavement deterioration rely on knowing the statistical distribution of traffic loads in the roadway. Existing systems are expensive to deploy. This paper describes a sensor network system for road pavement monitoring. It is capable of estimating the load of trucks in real-time and utilizes low deployment and maintenance cost wireless sensors. The approach relies on combining careful pavement models with data measured in real time and provides a reliable estimate of truck loads. Based on this estimates we are able to infer various pavement performance metrics under strict bounds.
