Keywords: Ground Penetrating Radar (GPR) (50), Traffic Speed Deflectometer (TSD) (4), Falling Weight Deflectometer (FWD), rapid pavement investigations, This technology can be used to determine pavement layering information where unknown, or to check the accuracy of. Noise-Modulated Ground Penetrating Radar (NM-GPR) is an emerging technology that enables rapid and non-destructive measurement of ‘as constructed’ pavement layering information. To enable better understanding and use of TSD measurements, knowledge of the pavement structure is also required. Introduction In recent years the Traffic Speed Deflectometer (TSD) has emerged as a device with significant potential for rapid non-destructive investigation of road pavement structural response. Keywords: Traffic Speed Deflectometer (TSD), Ground Penetrating Radar (GPR), Falling Weight Deflectometer (FWD), rapid pavement investigations 1. Similarities and differences between these measurements and an overview of the potential use of these techniques in combination are also discussed. Geospatial views of the data were developed to enable easier alignment, comparisons and better understanding of the road condition, by viewing these complementary data together and in the context of the surrounding environment. This paper presents a summary of recent field investigations using these devices and conventional Falling Weight Deflectometer (FWD) in combination. Abstract: The combined use of Traffic Speed Deflectometer (TSD) and Noise-Modulated Ground Penetrating Radar (NMGPR) technologies shows significant potential for rapid non-destructive investigation of road pavements.
