In the frame of a national project financed by the Austrian national road administration (ASFINAG) from summer 2013 to summer 2014 the Austrian Institute of Technology (AIT) performed a study on the long-term performance of several road surfaces currently used on the Austrian motorway. The scope of this study was to measure different asphalt and cement concrete pavements according to the following regulations: the Austrian trailer method according to the directive RVS 11.06.64, the international pass-by method according to ISO 11819-1 (also called SPB-method) and the international trailer method according to ISO/DIS 11819-2 (also called CPX-method). The present paper shows the main results of the measurements performed, as well as the time series including also data from a previous study performed by the Technical University of Vienna between 2006 and 2012. The results of these two studies were combined in order to compile a significant data basis.
