Comparison of noise characteristics of wearing courses with Mastic Asphalt (Gussasphalt) with designed surface (VSS2003/503)
Overview
Background & policy context:
In a test section on a cantonal road in the Canton Aargau three to four section, each in a length of about 100 m, with different wearing course will be placed. The noise behaviour and the development of noise characteristics and quality will be observed during two years.
Objectives:
The crucial objective of the project is to test the noise behaviour of Gussasphalt, Mastix asphalt, porous asphalt and asphalt concrete in a full scale test section.
Methodology:
There are field tests and field measurements at different layers performed, among others, two layers of mastic asphalt, which has been previously trimmed to "noise optimised properties" in the laboratory.
Field studies on various deck coverings and mastic asphalt with "constructed surface"will be provided in the other phase of the project.
