Workshop on the Curviameter: Interpretation and Exploitation of Measurements

On January 28 and 29 2015, the Belgian Road Research Centre hosted a workshop on the Curviameter. The objective of the workshop was to bring together specialists and users of Curviameter measurement data: current and former end-users of Curviameter data, road managers and road engineers, scientists who published articles about the interpretation of Curviameter data, and persons interested in the measurement device and in the data it provides.

The first Curviameter was introduced in the 1970ies. In 2015, the BRRC had been using one for 20 years. For long – and until 2005, when the world has seen the introduction of the first “Traffic Speed Deflectometer” (TSD) – it was the fastest deflection measuring device that was in use. Moreover, it delivers a “deflection bowl”, including the “maximum deflection” and the “radius of curvature”.

This workshop provided an informal meeting with no published papers. However, all presentations can be downloaded from the list of linked documents underneath.

All members of the DaRTS-group (“Deflections at Road Traffic Speed”) were also invited. Since its first meeting in 2012, the DaRTS group has developed into a globally recognised forum in the area of continuous deflection measurements obtained with Curviameter and TSD or other “high speed” deflection measurement devices like the Rolling Wheel Deflectometer (RWD). In this way the Curviameter workshop was also intended as an opportunity for DaRTS-members to meet experts on Curviameter data and to discuss topics related to the Curviameter that may be of more general interest.

Finally, the workshop offered a good opportunity for “networking”.
