Analysis of 2018-2024 Network Level Pavement Structural Testing with the TSD
The Traffic Speed Deflectometer (TSD) is a device used to measure the structural response of pavements while traveling up to the prevailing traffic speed. Virginia Department of Transportation (VDOT) has previously collected data on more than 8,000 lane miles of its roadway network using the TSD. This study seeks to combine thickness data from ground penetrating radar (GPR) and VDOT traffic data to calculate the remaining structural life of the network tested between 2018 and 2024 and to upload the data to VDOTs Pavement Management System.
