Evaluation of Traffic Speed Deflectometer for Collecting, Reporting, and Utilizing Network and Project Level Structural Data in Ohio

Currently, major rehab decisions and pavement management logic rely on the visual pavement condition survey (PCR). Traffic speed deflectometer (TSD) may have the ability to help further prioritize projects needing structural treatments or validate when they are not needed to help refine scopes in the work plan process. Ohio Department of Transportation (ODOT) does not currently use structural measurement in pavement management, so this could be an enhancement to that process. The goal of this research is to utilize a TSD to collect deflection data on ODOT's network, perform data analysis to determine the applications/limitations of the results, provide data analysis methodology utilizing commercially available software (MS Excel, TSD manufacturer, etc.), and to perform cost benefit analysis on the process.
