Development of a Pavement Condition Rating Tool for Improved and Rapid Network -level Assessment

Tuesday, June 10, 2025
4:45 PM – 6:00 PM MT
Abstract: Pavements are the most critical element of US transportation infrastructure. Pavement maintenance and rehabilitation are becoming more and more challenging tasks for transportation agencies. Specifically, the challenges stem from lane closure, time, and labor. The traditional pavement assessment techniques are extremely difficult to implement at the network level. Recently, the Traffic Speed Deflection Device (TSD) has been spotlighted due to its ability to measure pavement conditions at highway speeds. So far, TSD has been used in project level data collection. To this end, this study aimed at developing an improved pavement condition rating tool for network-level evaluation using TSD data. For this purpose, pavement conditions data from I-35 in Oklahoma was collected using TSD. In addition, pavement structure data was collected using a high-speed Ground Penetrating Radar (GPR). In addition, roadway cores were collected from selected locations of the test section. The GPR images were calibrated using the roadway cores. The TSD data was cleaned and analyzed to obtain several deflection basin parameters. Finally, the GPR and TSD data were combined to develop a network-level pavement condition rating system. The outcome of this study is expected to help the transportation agencies to make data driven decisions for pavement maintenance and rehabilitation.

Learning Objectives:

Attendees can expect to learn the following from this session:
  • have an insight into the pavement condition assessment at the network level.
  • understand the relationship between pavement surface geometry with internal pavement structure.
  • able to take data-driven decisions for pavement maintenance and rehabilitation.
