Evaluating the Traffic Speed Deflectometer (TSD) for network-level screening of pavements in Michigan
… move toward data-driven pavement management, the Traffic Speed Deflectometer (TSD) has emerged as an alternative non-destructive testing (NDT) technology that allows for continuous pavement data collection at traffic speed without having the need for lane closures. Its’ usage focus has been …

Network Level Decision-Making Using Pavement Structural Condition Information From The Traffic Speed Deflectometer
… condition information. However, since the traffic speed deflection devices use newer technology, there is a need for guidelines on how the state agencies could make use of this information for pavement management decision-making. This dissertation developed processes and enhanced tools to …

Use of the Traffic Speed Deflectometer for Concrete and Composite Pavement Structural Health Assessment: A Big-Data-Based Approach Towards Concrete and Composite Pavement Management and Rehabilitation
… not practical for network-level data collection. Traffic-speed deflection devices, among which the Traffic Speed Deflectometer [TSD], allow measuring pavement surface deflections at travel speeds as high as 95 km/h [60 miles per hour], and reporting the said measurements with a spatial resolution …

Development of structural condition thresholds for TSD measurements
… (a) results of a field evaluation of the Traffic Speed Deflectometer (TSD) in the United States (b) deflection thresholds to classify the pavement structural condition obtained from the TSD for a small subset of the Pennsylvania secondary road network. The results of the field evaluation …

Network-Level Structural Condition Data for Sustainable Pavement Asset Management
… data collection technologies. The falling weight deflectometer (FWD), while effective for point testing, is unsuitable for network-level applications due to its slow operation and traffic disruption. The traffic speed deflectometer (TSD), a continuous deflection measuring device, overcomes these …
