Description

This report documents discussions about international traffic speed deflectometer (TSD) data analysis and reporting held at the second Deflection and Road Traffic Speed workshop in Norway in June 2013. It also documents TSD data procurement and analysis processes from Poland that confirm the reliability of the ‘area under the curve’ method using data that was not typical of that encountered on flexible pavements in Australasia. ARRB has implemented interim operational procedures for a second generation TSD acquired for network strength testing in Australasia.
This research will help ensure the data collected for road agencies is reliable.
