Abstract:
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.
