Assessment of Continuous Pavement Deflection Measuring Technologies (SHRP 2 Prepublication Report*)
|
|
Greetings!
Nondestructive pavement evaluation devices can measure pavement deflections caused by a moving load, in some cases with little or no traffic control, which makes them more advantageous to use than stationary devices. SHRP 2 Project R06F (Development of Continuous Deflection Device) 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 can be useful for supporting pavement management. The final report documents the evaluation and includes a catalogue of existing continuous deflection measuring technologies and their characteristics.
* To make research available as early as possible, SHRP 2 is temporarily posting final reports that have been submitted by the research team, reviewed according to the relevant National Academy of Sciences procedures, and accepted for publication. These prepublication drafts, which have not been edited or formatted for publication, will be replaced by the final versions as they complete the editorial process.
