2014 - Australia - Traffic Speed Deflectometer: Data Review and Lessons Learned

This report documents a review and comparison of Falling Weight Deflectometer (FWD) and Traffic Speed Deflectometer (TSD) deflections, based on different approaches, at a network level. It
draws on the work undertaken for Austroads by Roads and Maritime Services of New South Wales (RMS) and the Department of Transport and Main Roads Queensland (TMR) in the evaluation and
assessment of the TSD for its application in Australasia. The report complements and is in direct response to the State-ofthe-Art review of current TSD practice completed under Austroads
Project AT1730 (this project which drew on information gained from attending the deflection at road traffic speed workshop held in the United Kingdom in June 2012. It also builds on earlier work under project AT1613 which defined six research goals for this area of work, and reported studies conducted on behalf of RMS and TMR.
