Assessment of Continuous Pavement Deflection Measuring Deflection Measuring Technologies
The measurement of pavement structural capacity is a critical input to perform structural analysis of in-service pavements, identify sections with structural capacity deficiencies at the network level, and design pavement renewal or rehabilitation treatments at the project level. Continuous deflection measuring devices are increasingly being used to support these and other pavement management business processes. These nondestructive pavement evaluation devices can measure pavement deflections caused by a moving load and, in some cases, with little or no traffic control. The ability to measure without disrupting traffic makes them more advantageous to use than stationary devices such as the falling weight deflectometer (FWD). SHRP 2 Renewal Research Project R06F, Assessment of Continuous Pavement Deflection Measuring Technologies, evaluated current technologies implemented in different types of continuous deflection measuring devices, identified the most promising devices for effectively supporting pavement management decisions, evaluated the capabilities of these devices, and identified and illustrated applications that could be useful for supporting pavement management. The main products of the project include a catalogue of existing continuous deflection measuring technologies; detailed assessment of the capabilities of the most promising devices; case studies illustrating the application of the technology for supporting various pavement management decision-making processes; a fact sheet describing the main technologies identified for continuously measuring pavement deflections and their potential uses; training materials for a workshop on the topic; research needs statements for the most pressing research identified, provided as an appendix; and a dissemination and implementation plan for the technology.
