Test section for noise reducing road surfaces, A12 - 2nd Tranche

06.06.2007 - 31.08.2008
Assigned research project
In the context of the research project a test section "noise-reducing road surfaces" was established on the A12 Inntal Autobahn. At this test track for the first time in Austria different innovative surface layer types have been examined under the same outside conditions regarding to their noise characteristics, their durability and their influences on road safety compared with conventionally used surface layer types. The examined surface layer types are 3 different kinds of noise-reducing stone mastic asphalt, one single layer porous asphalt, 2 different kinds of double layer porous asphalt and 2 reference surface layers (SMA 11 and pmAB 11). In the last two years two series of noise measurements had been accomplished. In the context of this research project another two years of measurements will be done at the test section.
