Pavement condition data collected by traffic speed deflectometer in NSW

Roads and Maritime used to collect pavement structural condition data using traditional equipment such as benkelman beam (BB), deflectograph (DFG) and falling weight deflectometer (FWD). Since 2015 Roads and Maritime has contracted ARRB Group to collect structural condition (ie deflection data) using ARRBs Traffic Speed Deflectometer (TSD). The ARRB TSD is now referred to as an intelligent pavement assessment vehicle (iPAVe). To date data collected from the Roads and Maritime network covers a total of over 36,500 km of roads and resulted in more than 3.6 million records. Apart from deflection data, the iPAVe also collected roughness, rutting, cracking, texture as well as video images. This paper discusses how the deflection data is being used in the Roads and Maritime pavement asset management environment. Studies conducted to determine the usefulness of the TSD deflection data indicated that there is potential for the TSD deflection data to be used in both network level and project level analyses. Detailed studies are recommended to explore full potential of the TSD deflection data. These studies should include various pavement types, climatic regions and traffic category and relationship with the traditional equipment.
