Satellite Assessment and Monitoring for Pavement Management

To minimize the obstruction to the traffic, this project aims to carry out investigation of the capability of remote sensing satellite data, including Synthetic Aperture Radar (SAR) satellite data for use in advanced infrastructure monitoring, which is a tangible breakthrough in remote sensing technology allowing to assess the pavement deformations with millimetric accuracy on single specific points. Recent developments in remote sensing satellite systems and availability of high-resolution Synthetic Aperture Radar (SAR) products have created an opportunity for SAR-based monitoring in pavement and infrastructure management. SAR Interferometry (InSAR) and developed advanced methods such as Permanent Scatterers SAR Interferometry (PSInSAR) and Advanced InSAR algorithm (SqueeSAR) are able to measure even small deformations and determine the deformation velocities over a set of images. Additionally, high-resolution SAR images may significantly increase the quality and level of detail in end products. Therefore, this newly emerging SAR-based monitoring has become valuable for monitoring and rehabilitating the nation’s deteriorating roadway infrastructure elements such as bridge settlements and displacements, roadway surface deformations, geohazards and sinkhole detection, historical analysis of problematic sites, etc. In this research study, the feasibility, accuracy, and effectiveness of use of satellite remote sensing technology, specifically SAR for pavement and infrastructure monitoring, were evaluated. A cost benefit analysis for a possible SAR-based monitoring system was performed. It was found that SAR-based methods are useful as a complementary tool rather than a replacement for current technologies and practices, specifically in a state of good repair.
