Incorporating Traffic Speed Deflection Devices Measurements into Pavement Management and Design
Traffic speed deflection devices (TSDDs) that measure surface deflection at traffic speeds are used by several highway agencies in the United States and other countries to provide data to help with management of the highway network. For example, these data can be used for assessment of pavement structural condition, selection of pavement treatments, and other purposes. In comparison with traditional pavement deflection measurement (e.g., falling weight deflectometers), TSDDs provide a means for acquiring extensive amounts of data in a short period of time that can be effectively used in pavement management and design. Recognizing that no widely accepted practices for incorporating the measurements obtained by TSDDs into pavement management and design are currently available, research is needed to identify the deflection-based measurements that are required for pavement structural assessment and other applications and develop a guide that presents procedures for incorporating these measurements into pavement management and design practices. The objective of this research is to develop a guide for incorporating TSDDs measurements into pavement management and design. The procedure contained in the guide shall be consistent with current practices for management and design of asphalt, concrete, and composite pavements.
