This report details the findings for Year 2 of the project, and is a continuation of the work from last year. The report is a continuation of work begun in 2015 into ways to utilise the Traffic Speed Deflectometer (TSD) as a detailed pavement structural evaluation tool. There are three parts in this study. Firstly, a correlation study to relate the Falling Weight Deflectometer (FWD) with the TSD. Secondly, the conduct of a trial field instrumentation installation to independently measure pavement surface motion. Thirdly, a comparison of TSD data obtained from successive years of surveying the Queensland road network.
