Utilization of Traffic Speed Deflectometer (TSD) for Pavement Management

The primary objectives of this research will be: (1) to show how the collected TSD data can classify structurally good, fair, and poor pavement sections for primary routes specifically for SCODT; and (2) to present how structural information can be used effectively for selection of potential rehabilitation candidates given limited resources. In addition, this project strives to provide: (1) a comparison of TSD measurements with PMS pavement condition data as the value of the TSD is its ability to collect structural information that is not currently captured by other parameters collected in a PMS; (2) development of structural indices which can classify structurally good, fair, and poor pavement sections; and (3) development of a best methodology to prioritize actual rehabilitation candidates with the collected TSD data in conjunction with current ranking criteria.
