Implementation of Structural Data from Traffic Speed Deflection Devices

Previous research has shown the benefit of including structural condition along with pavement surface condition in pavement management decision-making processes. Since 2018, 26 agency partners, plus the Federal Highway Administration (FHWA), have participated in Transportation Pooled Fund Study TPF 5(385) Pavement Structural Evaluation with Traffic Speed Deflection Devices (TSDDs) where structural condition data was collected on more than 50,000 miles of roadways across the United States. These data, along with new or enhanced analysis methodologies developed as part of this pooled fund research effort, have been used in a variety of ways that include: pavement performance forecasting that incorporates both surface and structural condition, network preservation and rehabilitation strategy planning, network-level screening, and project level investigation. A subset of the data collected as part of this pooled fund has also been incorporated within FHWA’s InfoMaterials web portal to make it readily available to the broader pavement community to support additional research and analysis efforts. This pooled fund study has also proved to be a convenient contracting mechanism assisting states with establishing pavement structural data collection programs. In addition, participation in the pooled fund study has provided agency partners with a means for collaboration with other agencies and leading researchers studying the best ways to analyze and implement pavement structural data into agency pavement management systems. TPF-5(385) comes to end in October 2023, and this proposed pooled fund study will continue with similar work. Most of the 26 agency partners of TPF-5(385) support starting this new pooled fund study. Objectives:The objectives of this follow-on pooled fund study include continuation of an existing research consortium that focuses on providing participating agencies guidance on how to specify and implement TSDD data within their respective pavement management systems and processes. Specific tasks within this multi-year program will be developed in cooperation with the partner agencies.
